Capturing traits providing heat stress tolerance in wheat using precision phenotyping
Indu Sharma and Ratan TiwariDWR, Karnal, Haryana, India
3rd Int. Plant Phenotyping Symposium organized by MSSRF, Chennai,Session 1: Breeding for novel traits, 17.2.2014
World’s population swells to ~ 9.6 billion in 2050
Strategy to enhance precision phenotyping for stress conditions
Screening of very large set of
genotypes
at hot spots requiring very
low input
Data acquisition in controlled
environment parameters
at specific crop stage but having bigger
plot size
Intensive multidimensional repeated data
acquisition taking few samples already identified through 1 & 2 ‐ Phenomics
1 2 3
Finally accepting realities and raising the bar –
Precision Phenotyping
• Climate is changing: no doubts• Abiotic & Biotic stresses dynamic & influenced by climate• Phenotyping methods evolved and rapidly in recent past• Innovative precision phenotyping mechanism developedIndia: A potential hub for multidimensional precise phenotyping
Including suggested planting strategy for enhanced precision phenotyping for stress conditions

Heat ToleranceThe work on screening of germplasm for drought resistance in wheat under AICW & BIP was initiated during 1977‐78 with the formulation of ‘National Drought Screening Nurseries’
1984‐85 National Heat Tolerance Screening Nursery (NHTSN) was conducted
Since 2000‐2001 efforts are being made to identify superior genotypes for particular traits under heat stress
Genotyping is relatively fast; Genome sequencing advancing
Phenotyping is still time consuming & labour intensive
Technological advances essential for high throughput
phenotyping
New Approaches (Marker Intensive) :Genome Wide Association Studies (GWAS)Genomic or Genome Wide Selection (GS)
