Abstract:
A dwarf mutant has been derived from M₂ gamma irradiated Morden population of sunflower (Helianthus annuus L.). The dwarf mutant has the height of 35 cm and the earliness of 65 days. This mutant has been selfed and forwarded to the M₃ and M₄ generations and it did not deviate significantly from the expected segregation ratio since it has the recessive monogenic character. Althogh the earliness and height showed a drastic reduction, the seed yield and oil content were on par with the parent Morden.
