Achivements in mutation breeding


Achivements in mutation breeding
    Achivements
    • Totally 1029 mutant varieties are released in India.
    • Disease resistance: Verticilium wilt resistance in peppermint, victorial blight resistance in barley, downy mildew resistance in pearl millet.
    • Modification of plant structure: E.g., bush habit in drybean, dwarf mutants in wheat and other cereals.
    • Nutritional quality augmentation: E.g. Opaque and floury endosperm mutants in maize
    • Chemical composition alteration: E.g., low ericic acid mutants of rape seed
    • Male sterility: for use in hybrid breeding in various crops
    • Horticultural variants: development of various floral mutants
    • Breeding of asexually propagated species: numerous species and traits
    • Development of genetic stock: various lines for breeding and research
    • Development of earliness: achieved in many species
       
    Merits
    • It can be used in inducing male sterility. eg: Ethidium di bromide
    • Cheap and rapid method as compared to other methods.
    • More effective for oligogenic traits.
