Induction of genetic variability in raya (Brassica juncea Coss)


, : Induction of genetic variability in raya (Brassica juncea Coss). Symposium on use of radiations and radioisotopes in studies of plant productivity: [Abstracts]: 29

When dry seed of RL18 and T59 were treated with 60-120 kR gamma rays, 0.5-0.9% ethyl methanesulphonate (EMS) and 0.05-0.09% methyl methanesulphonate, a significant change in mean values occurred for days to flowering, plant height, main shoot length and seed yield per plant in the M1-M3 generations, maximum genetic variability being induced in the first three characteristics, while EMS was the most effective mutagen.
