WHEAT & BARLEY NEWSLETTER
Director's MessageIt gives me immense pleasure to bring out the
current issue of Wheat & Barley Newsletter. I am also very
delighted to share that during 2017-18, once again, the country has
achieved a highest record wheat production of 99.70 mt which is
very close to the magical �igure of 100 mt from an area of 29.58
mha thereby registering an all-time high productivity of 3371
kg/ha. Similarly, in barley also the country harvested a record
production of 1.77 mt from an area of 0.66 mha achieving a record
average productivity of 2679 kg/ha. Inter alia, coordinated
research, conducive environmental conditions, governments
pro-farmers' policies and farmers hard work contributed towards
achieving good productivity in both the crops across regions
facilitating the farmers to be on the track of “Doubling the
Farmers Income by 2022” as envisioned by the Hon'ble Prime Minister
of India.
Varieties play a crucial role in the productivity of any crop.
During the reported period a total of seven new varieties of wheat
(K 1317, DBW 168, DBW 173, UAS 375, HI 1612, MACS 4028 (d) and HI
8777 (d)) and one variety of barley (DWRB 137) were released by the
Central Sub-Committee on Crops Standards, Noti�ication and Release
of Varieties for Agricultural Crops (CVRC) for different production
conditions and agro-ecological zones in the country. In addition to
varietal development, fourteen genetic stocks of wheat and four of
barley were registered by NBPGR, New Delhi.
Keeping in view the farmers welfare, ICAR-IIWBR focuses on
research and outreach programmes which helps to reduce the cost of
cultivation and increase the pro�it with rational use of natural
resources and eco-friendly technologies.
I feel extreme proud to share that recently the wheat programme
of the country bagged the prestigious BGRI Gene Stewardship Award
at Marrakech, Morocco in recognition of outstanding work done by
the Indian wheat programme which was received by Dr T Mohapatra,
Secretary DARE and DG ICAR.
The current issue of this Newsletter presents the salient
research �indings on various aspects of wheat & barley crops,
awards and other accomplishments from ICAR-IIWBR. I thank all the
wheat and barley research workers and acknowledge their kind
support for ending this crop season on a high note with record
production.

Grain hardness is an important trait in wheat quality with a
profound effect on milling, baking and end-use qualities of wheat.
It is common to differentiate soft and hard wheat in the world
trade for product speci�ic utility. Soft wheat is more friable,
requires less energy to mill and produces �lours and meals with
�iner particles and lower starch damage; suitable for cake and
biscuit production. Soft grain textured wheat produces tender and
larger biscuits.
QLD 84 was developed at ICAR-Indian Institute of Wheat and
Barley Research (ICAR-IIWBR) by crossing
t h t h3 7 I B W S N 0 5 / 3 6 I B W S N 1 3 8 ( P e d i g r e e
: MIANYANG20/3/CMH84.3379/ CMH78.578// MILAN). The genotype was
evaluated at 13 centers in Quality Component Screening Nursery
(QCSN) for three consecutive years (2015-16, 2016-17 and 2017-18).
QLD 84 was found to be superior with 18 grain hardness index over
the years and locations to all the
testing genotypes and soft grain check variety HS 490 (Table 1).
QLD 84 recorded the lowest grain hardness index in all the 13
tested centers compared to the best check variety (HS 490) for low
grain index. QLD 84 recorded lowest grain hardness index of 19, 18
and 18, respectively during 2015-16, 2016-17 and 2017-18. Whereas,
the check variety HS 490 tested in 2015-16 (grain hardness index:
27) and 2017-18 (grain hardness index was 35). QLD 84 was 41.9%
superior over check variety HS490. Low grain hardness index is very
important factor to obtain high spread factor of biscuit and better
biscuit quality. Thus, QLD 84 could be a potential source to be
utilized in future breeding programs to develop bread wheat
varieties suitable for better biscuit making.

Grain protein is an important trait that determines the
nutritional quality and baking properties of wheat. It is one of
the major pricing factors for wheat trading at global market and is
an important nutritional factor for

human health. Protein is an essential component of cells and it
supports muscle growth, immune system and enzymatic reactions.
Protein-energy malnutrition causes Marasmus and Kwashiorkor. Grain
yield and grain protein content through its contribution to end-use
quality, are the two most important characters determining the
economic value of bread wheat.
QLD 11, a promising bread wheat genotype was
thselected from 15 High Rainfall Wheat Screening Nursery (HRWSN)
with the parentage of MURGA. The genotype was evaluated at 12
locations along with high protein check variety (UP 2672) during
2015-16 and 2016-17 under Quality Component Screening Nursery
(QCSN). QLD 11 was found to be superior with 14.48% protein content
over the years and locations to all the testing genotypes and check
variety UP 2672 (14.06%)
(Table-2). QLD 11 recorded high grain protein content in all the
12 tested centers compared to the best check variety (UP 2672) for
high grain protein content. QLD 11 recorded high grain protein
content of 14.83% and 14.13% during 2015-16 and 2016-17
respectively, whereas; the check variety UP 2672 recorded 14.39%
and 13.72%, respectively during 2015-16 and 2016-17. Thus, QLD 11
could be a potential source for utilization in future breeding
programs to improve grain protein content of bread wheat
varieties.

Sedimentation value measures the strength of gluten and
determines the wheat for speci�ic utility. Weak, medium and strong
gluten as measured by low, medium and high sedimentation value are
best suited for biscuit, chapatti and bread making, respectively.
Sedimentation value is being used as a screening tool in wheat
quality breeding programs globally to develop product speci�ic
wheat cultivars. The genotypes were
evaluated at 15 centers in Quality Component Screening Nursery
(QCSN) during 2017-18. QLD 93, QLD 94, QLD 98, QLD 99, QLD 100, QLD
101, QLD 102, QLD 103 were found to be superior to the best
performing check UP 2672. QLD 93, QLD 94, QLD 98, QLD 99, QLD 100,
QLD 101, QLD 102, QLD 103 recorded high sedimentation value of
64.8, 65.3, 66.1, 65.5, 66.0, 66.8, 67.2, 65.5, respectively.
Whereas, the check varieties C 306, HS 490, UP 2672 and NIAW 1415
recorded sedimentation value of 46.4, 46.4, 45.5 and 49.7,
respectively. These genotypes with high sedimentation value could
be potential donors to be utilized in bread wheat improvement
program.

genotype, DBW 218 was identi�ied as a promising genotype
possessing high sedimentation value, grain protein content and
grain hardness along with acceptable yield.
The new wheat genotype DBW 218 was developed at ICAR-IIWBR,
Karnal, from the cross PRL*PASTOR// PBW343*2/KUKUNA through
pedigree method of breeding. This genotype was evaluated at total
nine locations including �ive locations (Delhi, Karnal, Hisar,
Ludhiana and Gurdaspur) of North Western Plains Zone (NWPZ) and
four locations (Faizabad, Kanpur, Pusa and Sabour) of North Eastern
Plains Zone (NEPZ) along with the three checks (DBW 71, WR 544, DBW
14) under very late sown trial during 2016-17 for grain yield,
disease resistance and quality traits and this followed as
criterion for selecting genotypes for end product purpose.
The key determinants for making good quality chapatti
05
are sedimentation value (30-60 ml), grain protein content
(11-13%) and grain hardness (40-75). Sedimentation value gives an
idea of gluten strength. DBW 218 showed high sedimentation value of
57ml pooled over both the zones (NWPZ & NEPZ) coupled with
desired level of protein content (12.7%) and grain hardness (76) as
compared to check varieties (Table 4). Besides quality traits, the
genotypes showed comparable performance for other agronomic
characteristics over checks in both the zones indicating its
wider adaptability (Table 4). Thus, DBW 218 is a high yielding
genotype having desired level of disease resistance and was found
exceptionally good for chapatti making (high sedimentation value,
grain protein content and grain hardness traits). This promising
genotype may be utilized as donor parent (quality, yield and short
duration) in breeding programs to improve chapatti quality.

Climate change has exposed the wheat crop to higher temperatures
during crop growth stages. The international nurseries and trials
from CIMMYT, Mexico contributed variable germplasm lines suitable
for different environmental conditions. The elite germplasm lines
included in the semi arid wheat screening nursery (SAWSN) and semi
arid wheat yield trial (SAWYT) were developed for their suitability
to semi arid areas. These
entries were evaluated at IIWBR during 2017-18 for days to
heading, maturity, plant height, grain number per spike,
1000-grains weight, grain yield and disease resistance. A wide
range was observed for the traits under observation. In SAWYT and
SAWSN, high incidence of yellow rust was also observed in most of
the lines with incidence as high

genotype, DBW 218 was identi�ied as a promising genotype
possessing high sedimentation value, grain protein content and
grain hardness along with acceptable yield.
The new wheat genotype DBW 218 was developed at ICAR-IIWBR,
Karnal, from the cross PRL*PASTOR// PBW343*2/KUKUNA through
pedigree method of breeding. This genotype was evaluated at total
nine locations including �ive locations (Delhi, Karnal, Hisar,
Ludhiana and Gurdaspur) of North Western Plains Zone (NWPZ) and
four locations (Faizabad, Kanpur, Pusa and Sabour) of North Eastern
Plains Zone (NEPZ) along with the three checks (DBW 71, WR 544, DBW
14) under very late sown trial during 2016-17 for grain yield,
disease resistance and quality traits and this followed as
criterion for selecting genotypes for end product purpose.
The key determinants for making good quality chapatti
05
are sedimentation value (30-60 ml), grain protein content
(11-13%) and grain hardness (40-75). Sedimentation value gives an
idea of gluten strength. DBW 218 showed high sedimentation value of
57ml pooled over both the zones (NWPZ & NEPZ) coupled with
desired level of protein content (12.7%) and grain hardness (76) as
compared to check varieties (Table 4). Besides quality traits, the
genotypes showed comparable performance for other agronomic
characteristics over checks in both the zones indicating its
wider adaptability (Table 4). Thus, DBW 218 is a high yielding
genotype having desired level of disease resistance and was found
exceptionally good for chapatti making (high sedimentation value,
grain protein content and grain hardness traits). This promising
genotype may be utilized as donor parent (quality, yield and short
duration) in breeding programs to improve chapatti quality.

Development of new cultivars for warmer areas requires high
yield potential in target environments along with resistance to
rust and leaf blight diseases. A total of 120 advanced genotypes
developed for warmer areas were evaluated for resistance to rust
and leaf blight diseases during 2017-18 crop season under
epiphytotic conditions at three hot spot locations, namely Karnal
for stripe rust, Vijapur for stem rust and Faizabad for leaf rust
and leaf blight. For disease creation, mixtures of most virulent
pathotypes were used viz., 46S119, 110S119, 47S103 and 110S84 for
stripe rust, 12-5, 77-9, 77-5 and 104-2 for leaf rust and 11, 40A,
42, 122 and 117-6 for stem rust. Leaf blight inoculums maintained
at Faizabad centre was used for creating the disease. The rust
disease severity was 0-80S for stripe & leaf rust and 0- 40S
for stem rust. The leaf blight score ranged from 35-78 on double
digit scale. Out of 120 genotypes; 10, 67 and 37 genotypes were
found immune to stripe, leaf and stem rust, respectively whereas
�ive entries namely PYT17-33 (DBW 87/DBW 92), PYT 17-62 (WH 542/UP
2338), PYT 17-95 (MP 1234/HD 2967), PYT 17-99 (DBW
87/DBW 16) and PYT 17-101 (WH 542/DBW 16) showed resistance
reactions to all three rusts and leaf blight. Some of these
promising lines may be further utilised as potential donors for
disease resistance.

improvement contributed 13 elite germplasm lines including 5
released cultivars (DBW 17, DBW 71, DBW 93, DBW 107 & DBW 110),
4 genetic stocks (PHSL 5, PHSL 10, PHSL 11, DBW 129) and 4 new
germplasm lines (DBW 172, DWAP 1530, DWAP 1531, DWAP 1541) in
National Genetic Stock Nursery during 2017-18. These l ines were
evaluated at 34 cooperating centres alongwith check varieties
Sonalika and HD 2967. The data from 34 locations was pooled for
various yield component traits, namely, days to heading, days to
maturity, plant height (cm), tillers/m, grain number/spike,
1000-grains weight (g) and spike length (cm) that showed wide range
of variability. Trait-wise analysis indicated better performance of
DWAP 1531, PHSL 5, PHSL 10, PHSL 11, DBW 11 & DBW 107 for early
heading and maturity; DWAP 1530 & DBW 129 for tiller number per
m row; PHSL 5, PHSL 10, DWAP 1531 and DWAP 1541 for 1000-grains
weight and spike length. Based on overall performance for yield
component traits across the locations, genotypes DWAP 1531, PHSL 5
and PHSL 10 showed better performances for three or more traits in
combination compared to the respective best check variety. In these
lines, iron and zinc
content was also estimated using XRF machine. The iron and zinc
contents ranged from 32.3 to 41.5 ppm and 28.0 to 35.4ppm,
respectively. High amount of iron was observed in DBW 107, PHSL 5
and DBW 71 whereas PHSL 10, DBW 17, PHSL 5, DBW 93 and DWAP 1531
showed higher amount of zinc content as compared to check
varieties. Based on above results, DWAP 1531, PHSL 5 and PHSL 10
were found promising donors for various traits which can be further
utilized in wheat improvement programmes.

Development of new cultivars for warmer areas requires high
yield potential in target environments along with resistance to
rust and leaf blight diseases. A total of 120 advanced genotypes
developed for warmer areas were evaluated for resistance to rust
and leaf blight diseases during 2017-18 crop season under
epiphytotic conditions at three hot spot locations, namely Karnal
for stripe rust, Vijapur for stem rust and Faizabad for leaf rust
and leaf blight. For disease creation, mixtures of most virulent
pathotypes were used viz., 46S119, 110S119, 47S103 and 110S84 for
stripe rust, 12-5, 77-9, 77-5 and 104-2 for leaf rust and 11, 40A,
42, 122 and 117-6 for stem rust. Leaf blight inoculums maintained
at Faizabad centre was used for creating the disease. The rust
disease severity was 0-80S for stripe & leaf rust and 0- 40S
for stem rust. The leaf blight score ranged from 35-78 on double
digit scale. Out of 120 genotypes; 10, 67 and 37 genotypes were
found immune to stripe, leaf and stem rust, respectively whereas
�ive entries namely PYT17-33 (DBW 87/DBW 92), PYT 17-62 (WH 542/UP
2338), PYT 17-95 (MP 1234/HD 2967), PYT 17-99 (DBW
87/DBW 16) and PYT 17-101 (WH 542/DBW 16) showed resistance
reactions to all three rusts and leaf blight. Some of these
promising lines may be further utilised as potential donors for
disease resistance.

improvement contributed 13 elite germplasm lines including 5
released cultivars (DBW 17, DBW 71, DBW 93, DBW 107 & DBW 110),
4 genetic stocks (PHSL 5, PHSL 10, PHSL 11, DBW 129) and 4 new
germplasm lines (DBW 172, DWAP 1530, DWAP 1531, DWAP 1541) in
National Genetic Stock Nursery during 2017-18. These l ines were
evaluated at 34 cooperating centres alongwith check varieties
Sonalika and HD 2967. The data from 34 locations was pooled for
various yield component traits, namely, days to heading, days to
maturity, plant height (cm), tillers/m, grain number/spike,
1000-grains weight (g) and spike length (cm) that showed wide range
of variability. Trait-wise analysis indicated better performance of
DWAP 1531, PHSL 5, PHSL 10, PHSL 11, DBW 11 & DBW 107 for early
heading and maturity; DWAP 1530 & DBW 129 for tiller number per
m row; PHSL 5, PHSL 10, DWAP 1531 and DWAP 1541 for 1000-grains
weight and spike length. Based on overall performance for yield
component traits across the locations, genotypes DWAP 1531, PHSL 5
and PHSL 10 showed better performances for three or more traits in
combination compared to the respective best check variety. In these
lines, iron and zinc
content was also estimated using XRF machine. The iron and zinc
contents ranged from 32.3 to 41.5 ppm and 28.0 to 35.4ppm,
respectively. High amount of iron was observed in DBW 107, PHSL 5
and DBW 71 whereas PHSL 10, DBW 17, PHSL 5, DBW 93 and DWAP 1531
showed higher amount of zinc content as compared to check
varieties. Based on above results, DWAP 1531, PHSL 5 and PHSL 10
were found promising donors for various traits which can be further
utilized in wheat improvement programmes.

Net effect of plant–microbe interactions on plant growth could
be positive, neutral or negative. All those
bacteria inhabiting plant roots and in�luencing the plant growth
positively by any mechanism are referred to as plant
growth-promoting rhizobacteria (PGPR). A large number of Bacillus

amyloliquefaciens, B. pumilus, B. licheniformis, B.
thuringiensis, B. cereus, B. megaterium, and many others. Bacillus
spp. enhance plant growth in many ways: a) by controlling pathogens
via induced systemic resistance (ISR), b) by synthesizing
antibiotics, c) by producing plant hormones such as indole-3-acetic
acid (IAA), cytokinin, and gibberellic acid (GA) and d) by acting
synergistically with nitrogen-�ixing or phosphorous-acquiring
symbiotic microbes. PGP bacilli are commonly detected in the
rhizosphere, phyllosphere, or as endophytes. The Bacillus strains
(B. subtilis, B. simplex, B. pumilus, and B. megaterium) which were
earlier found to show in-vitro plant growth promoting activities is
used in the present study. Effect of Bacillus strains on the growth
of plant was studied by seed germination test in wheat.
Wheat is a staple food crop of many countries and constitutes
nearly one-third of the total cereals consumed globally. Hence, a
preliminary study was conducted to study the effect of plant
growth-promoting on wheat ( ) Bacillus spp Triticum aestivumgrowth
and development. Wheat varieties viz. Raj 3765 and DBW 90 were used
for the study under late sown conditions. Wheat seeds were surface
sterilized by exposing to 95% ethanol and immersing in 0.2% HgCl
2solution for three minutes. The seeds were then subjected to �ive
times washing with sterile distilled water. One ml of overnight
grown bacterial culture (107-106 cells/ml) was applied on each seed
for 10 min and treated seeds were dried. For seed germination test
the sterile non treated dried seeds as control, soaked with non
inoculated media for 10 min and the treated dried seeds were kept
on sterilized wet blotting paper and incubated at 30 C for 2-7
days. The o
percent seed germination and root length were measured.
In germination test, the percentage seed germination
of treated seeds was found high (55-70%) as compared to control
(30-45%). The germinated seedlings has been recorded with a root
length ranging from 3.1 to 3.7cm and shoot length from 2.4 to
3.1cm, while untreated seedling/control has root and shoot length
of 1.9-2.5cm and 1.1-1.3cm, respectively. The number of roots was
also more in the treated seeds (5-6) as compared to control (2-4)
(Fig. 2(a&b).
The data obtained from seed germination study demonstrated
positive effect of . on root and Bacillus sppshoot elongation
compared to control. This indicates that Bacillus strains (B.
subtilis, B. simplex, B. pumilus, and B. megaterium) can improve
the plant growth and thus can be considered as an effective
PGPR.

order to support local seed demand and breeder seed requirement
of its varieties, a small scale seed
thproduction programme was taken up. During 12 �ive year plan
(2012-17), total breeder seed indent of IIWBR bred varieties was
10374.6 q against which 11238.7 q breeder seed was produced with a
surplus of 864.1 q. During this period, the share of IIWBR breeder
seed production in national breeder seed production was 9.7%. This
quantity of breeder seed produced was expected to produce 7024188 q
certi�ied seed at seed multiplication ratio of 1:25 which can cover
more than 7.0 million ha wheat area. During 2017-18, an indent of
1687.9q breeder seed of 10 varieties was received.
IIWBR is instrumental in development and release of improved
wheat varieties for all four major zones. Wheat varieties DBW 17,
DPW 621-50 and DBW 88 were released for irrigated timely sown
conditions whereas, DBW 16, DBW 71 and DBW 90 were released for
irrigated late sown conditions of the NWPZ. Similarly, CBW 38 and
DBW 39 were released for timely sown and DBW 14 and DBW 107 for
late sown conditions in irrigated areas of the NEPZ. DBW 110 and
DBW 93 were released for limited irrigation conditions of CZ and
PZ, respectively. Among these varieties, IIWBR produced maximum
seed of DPW 621-50 (3743.9 q) followed by DBW 17 (3691.9 q) which
was
surplus against the indented quantity. Among late sown
varieties, maximum seed was produced for DBW 16 followed by DBW 14,
DBW 90, DBW 71 and DBW 107 of which only DBW 14, DBW 71 and DBW 107
showed surplus production. During 2017-18, the total indent of
IIWBR bred varieties is 1687.9q with highest indent of DBW 110
(359.0 q) followed by DPW 621-50 (271.6 q), DBW 107 (231.6 q), DBW
88 (226.6 q) and DBW 17 (178.5 q). Besides these, three more
varieties namely WB 2 (Zn rich variety for timely sown, NWPZ), DBW
173 (late sown, NWPZ) and DBW 168 (timely sown, PZ) have been
released which are yet to enter seed chain along with DBW 93. These
varieties have increased demand among farmers and are expected to

Loose smut caused by fungus Ustilago tritici (Pers) Rostr. is an
exclusively seedborne disease of wheat and triticale in cooler
climate. Disease is primarily managed using disease free seeds as
well as use of pre-sowing seed treatment using systemic fungicides
like c a r b o x i n , c a r b e n d a z i m , t e b u c o n a z o
l e a n d thi�luzamide. However, these fungicides are often not
used by farmers in developing countries due to ignorance, nature of
diseases and its source of primary inoculums and high cost of seed
treatment. A total of 1,119 numbers of high yielding bread wheat
(Triticum aestivum), durum wheat (T. durum), Khapli wheat (T.
dicoccum) and triticale genotypes and varieties along with a highly
susceptible check variety, Sonalika, were evaluated against loose
smut in India. The evaluation against loose smut was done at hot
spot locations, Almora in Northern Hills Zone, Ludhiana, Hisar and
Durgapura in North-Western Plains Zone of India under arti�icially
inoculated conditions using local isolates of pathogen from 2012-13
to 2017-18 crop seasons. A list of highly resistant (HR or free)
and resistant (R having 0.1-5.0% infection) genotypes and released
varieties of Wheat and triticale is given in Table 9.
These genotypes may be used as a donor parents for breeding of
disease resistant varieties in Wheat and Triticale. The resistant
varieties may be used for deployment in disease endemic areas to
curtail losses in yield and reducing use of seed dressing systemic
fungicides.

The post harvest grain analysis for presence of Karnal bunt in
grains of farmers’ �ield collected from different regions was done
by different cooperating centres of All India Coordinated Research
Project on Wheat and Barley during April-June 2018. The Karnal bunt
incidence was lower during 2017-18 crop season as compared to
previous years. The report is given below:
Jammu
Out of 383 samples collected from Jammu region, 31 (8.09%)
samples were having Karnal bunt (KB) infection in the range of
0.01-8.98%. Samples from Jammu were having higher percentage of KB
followed by Samba, Kathua and Udhampur whereas samples from Rajouri
were free from KB.
H. P.
Karnal Bunt was observed in samples of variety HD 2967, PBW 621,
DBW 621-50, HPW 236 and VL 829 in the range 0 .04-0.12 % in

Punjab
A total of 2380 samples were collected from 164 grain markets of
Punjab state and 671 (28.19%) samples showed Karnal bunt infection.
Among different districts, samples from Pathankot showed highest
incidence of KB (81.82%) followed by Amritsar and Kapurthalla. The
range of per cent KB infected samples was from 8.26 to 81.82. The
severity of KB was highest in Amritsar district followed by
Kapurthalla. The range of KB infection in other districts was
0.2-0.9% with average infection of 0.2%.
Haryana
A total of 1867 samples collected from both Southwest and
Northeast Haryana and analysed for presence of KB and revealed that
49.5% samples were infected with KB and range of infection was
0.5-2.0%. The KB infection was higher in Southwest Haryana (60.3%)
as compared to Northeast Haryana (38.6%) which seems to be a major
shift in KB distribution. The highest KB infected samples were in
districts Dadri and Mahendragarh (100%) followed by Bhiwani
(97.3%), Hisar (93.4%), Rewari (83.9%) and Gurugram (80.0%). It may
be due to use of sprinkler irrigation as well as little use of
rice-wheat cropping system. The least KB infected samples were from
districts, Fatehabad (2.5%) followed by Sirsa (6.1%), Jind (8.8%),
Ambala (9.3%) and Rohtak (14.3%).
Rajasthan
A total of 249 samples collected from Alwar, Dausa and Jaipur
were analysed for presence of KB and 122 samples (49%) were having
KB in the range of 0.1-20.2%. A decreased trend in the KB incidence
was witnessed during 2017-18 as compared to last crop season which
may be due to no rains in months of the February and March
accompanied with high temperature at booting stage of crop.
U. P.
In district Faizabad, a total of 107 wheat grain samples were
collected and examined for Karnal bunt. Karnal bunt was detected in
varieties, PBW 154, PBW 502, PBW 343, Lok 1, Sonalika, HD 2329, HD
2733, HD 2967, HP 1633, HP 1731 and HP 1741. Highest percent of KB
was recorded in variety HD 2329(0.8%) where as Sonalika has lowest
percent (0.1%) infection.
M. P.
A total of 400 wheat grain samples collected from different
mandi's of Indore and Dewas during April and May, 2018 were
analyzed for Karnal bunt infection and none of the samples found
was infected with the disease. Likewise, a total of 234 wheat grain
samples from 104 villages of 7 blocks across the two districts viz.
Hoshangabad and Narsinghpur were collected and examined for KB.
Like previous years, none of the grain samples collected so for had
KB symptoms.
Gujarat
Eleven different marketing yards and various farmers' fields
located in different wheat growing areas of North Gujarat were
surveyed for wheat seed health status. A total of 524 seed samples
from marketing yards and 207 samples from farmers' fields were
examined. The data indicated that like previous years, all the
samples were free from Karnal bunt incidence.
Maharashtra
A total of 180 wheat grain samples were collected from
Nandurbar, Akkalkuan, Kopargaon, Chalisgaon, Niphad, Shahada,
Chandwad, Nashik and Dindori in the state and like previous years,
no KB infection was found.
Karnataka
A total of 175 wheat samples were collected from Badami,
Bagalkot, Mudhol, Athani, Chikkodi, Gokak, Hubli and Navalgund and
analysed for the presence of KB. None of the sample showed KB
infection and it was found

Karnataka is free from KB over years.
It is concluded that KB incidence in Northwestern states is
declining which may be due to rice wheat cropping system and lack
of rains and fog at boot leaf stage. Unlike this in some drier
districts of Haryana, KB incidence rise in may be due to large
scale adoption of sprinkler irrigation and little rice-wheat
cropping system area. Like previous years, during 2017-18 crop
season also M. P. and Gujarat (Central Zone) and Maharashtra and
Karnataka (Peninsular Zone) remained free from KB and may be used
for KB free wheat production.
Characterization of microbial diversity associated with corn
leaf aphid, Rhopalosiphum maidis (Fitch) infesting wheat crop

Cereal aphids are serious pests causing damage either directly
or by the transmission of viruses in many areas all over the world.
Direct effects of aphid feeding on cereals include yellowing and
premature
death of leaves, stunting of the stems and reduction in grain
size. Aphids inject toxic salivary secretions during feeding and
can cause signi�icant reduction in grain protein. Aphids have
become a model system of insect-symbiont interactions as their
associations with microbes are widespread in nature and can lead to
bene�icial or parasitic interactions.
Aphid endosymbionts have frequently been studied by PCR-based
techniques, using species-speci�ic primers, nevertheless this
approach may omit other non-target bacteria co-habiting a
particular host species. Advances in high-throughput sequencing
technologies are complementing our knowledge of microbial
communities by allowing us to study the whole microbiome of
different organisms. Using 16S microbiome pro�iling sequencing, we
compared microbiome diversity and abundance among

The corn leaf aphid (CLA), Rhopalosiphum maidis (Fitch), is a
serious economic pest of wheat in North Western Plains Zone of
India. Host plant resistance is the preferred method to control CLA
infestations. It has been observed that host plant tends to
minimize the damage caused by aphid feeding, while aphids tend to
manipulate plant response by suppressing plant defense mechanisms
or developing strategies to overcome plant defense systems. Both
evolve many strategies to successfully exploit or respond to
reciprocal adaptation and defense reactions.
In this study, transcriptome assembly and gene expression
analyses of the wheat leaf samples before and after feeding by
aphids using Illumina RNA sequencing was performed. The gene
expression of tolerant wheat variety, HD 2967 was compared to
susceptible genotype, A-9-30-1 before and after infestation by CLA.
The transcriptome pro�iling of two genotypes before feeding by
aphid (uninfested) generated 47,952 genes, out of which 8378 were
expressed only HD 2967 and 1074 were expressed in A- 9 - 3 0 - 1 .

information that could facilitate our understanding of the
molecular mechanisms underlying feeding, ingestion and digestion.
Furthermore, analysing and identifying the genes related to aphid
resistance in wheat. These �indings will provide a fundamental

Susceptibility of few wheat cultivars to major storage
insect-pests
Poonam Jasrotia, PL Kashyap and Sudheer Kumar
ICAR-Indian Institute of Wheat and Barley Research, Karnal
Worldwide, grain production has been steadily increasing due to
advances in production technology, but at the same time improper
storage is causing high losses in grains which sometimes can
surpass the losses that crop actually suffer in the �ield. In
India, post-harvest losses caused by unscienti�ic storage, insects,
rodents, microorganisms etc., account for about 10 per cent of
total food grain production. Losses alone by insects have been
estimated to be between 5-10 % and these not only include the
direct consumption
of kernels, but also include accumulations of frass, exuviae,
webbing and insect cadavers that signi�icantly affect quality of
seed and may result in grain that is un�it for human consumption.
About 500 species of insects have been associated with stored grain
products out of which 100 insect pest species of stored products
cause economic losses. Storage insect pests are categorized into
two types viz. primary and secondary pests. Primary pests are those
that damage whole grains while secondary pests damage broken or
already damaged grains. Primary pests are further categorized into
internal (Sitophilus oryzae and Rhyzopertha dominica) and external
feeders (Tribolium castaneum) based on place of their attack.
The staple cereals, such as rice, maize, wheat, barley, oats and
sorghum vary quite signi�icantly in their inherent resistance or
susceptibility to both �ield and post-harvest insect infestations
in storage by the more recognized grain storage insects. Keeping in
mind, an experiment at IIWBR Karnal was conducted to determine the
susceptibility of popular wheat varieties to storage insects;
Sitophilus oryzae, Rhyzopertha dominica and Tribolium castaneum.
The freshly harvested 25g pest-free seed of each variety was taken
in petri dishes and 10 adults of each insect were introduced into
each perti dish. Observations were recorded on orientation
behaviour, life span duration and percent weight loss to grain. It
was found that the highest orientation behaviour (9.2 adults) was
shown by R. dominica on variety DBW 88 and lowest (5.0) in variety
HD 2967 (Fig.14).The longest duration of 49 days to complete life
span was taken by S. oryzae on varieties DBW 101 and DBW 88.
However, the shortest duration of 31 days was taken by R. dominica
on variety WB 2 to complete its life cycle (Fig.15). The
highest
percent loss (42.18) in grain weight was recorded on variety DBW
88 by caused S. oryzae and Tribolium casteneum infestation. The
lowest damage of 11.45% was caused by R. dominica in variety HD
2967 (Fig.16)
The preliminary � indings wil l be useful for determining the
levels of inherent resistance or susceptibility of wheat varieties
and will ease in understanding the mechanisms underlying those
phenomenon.
