Taxonomy of Rose :-
Scientific Name : Rosa indica
Chromosome No. : 2n = 14
Family : Rosaceae

The rose is the world’s most favourite and popular romantic flower.
History and symbolism, colour and fragrance, and sheer elegance of from-all
combine to give the rose its pre-eminent position.
The rose is one of the important crops grown for its cut flowers.
The genus Rosa comprises 120 species and there are more than 30,000
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.
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
