ROSE (Rosa indica)

Taxonomy of Rose :-

Scientific Name : Rosa indica

Chromosome No. : 2n = 14

Family : Rosaceae

cultivars which are extensively distributed in the temperate and subtropical

parts .

All the present day remarkable changes in growth habit, flowering and

flower shape, from, colour, size and fragrance of modem roses have been due

to chance crossing, selective crossing, bud sports, induced mutations,

molecular breeding and selections.

Breeding objectives:

Continuous blooming – free flowering or recurrent blooming

Brilliant and fragrant flower

Uniform flower shape, form and size

Growth should be vigorous – Improved appearance of plant

Floriferous nature

Winter hardiness

Evergreen plant type and foliage attractiveness

Long shelf life with less `petal shedding.

Resistance to pests and diseases (powdery mildew, black spot, scale insect)

Thorn less nature

Developing blue and purple coloured varieties as they are in great demand.

Rose flower with thorns Without thorns

1. Natural crossing and selection

2. Hybridization Ex: Anurag, Chandrama and Chandrika

3. Breeding for disease resistance

4. Breeding for Better Red Rose – Cyanidin,‘Chrysanthemin’ and ‘Paeonin’

5. Induced mutation:

6. Polyploidy Breeding:

7. Molecular Breeding
