B. Rai et H. Kumar, ISOLATION AND CHARACTERIZATION OF USEFUL MUTANTS INDUCED BY GAMMA-IRRADIATION IN KRANTI INDIAN MUSTARD (BRASSICA-JUNCEA), Indian Journal of Agricultural Sciences, 68(1), 1998, pp. 16-17
Genetic variability was induced in the 'Kranti' indian mustard [Brassi
ca juncea (L.) Czernj. & Cosson], utilizing 30, 40 and 50 kr doses of
gamma-ray irradiation. In M-3 generation, compared with the control, s
ubstantial decrease was observed in the mean values of various quantit
ative characters in the mutagen-treated populations. More variation wa
s induced at 30 kr compared with that at 40 or 50 kr dose. Four mutant
s were identified at 30 kr dose, which besides being early in maturity
, gave better yield also-compared with the control. The better seed yi
eld of the transmutated plants was due either to increase in sed weigh
t or to increase in number of siliquae/plant.
