Induction of mutation in pea by gamma irradiation

A study on gamma rays induced mutations in the variety Bonneville of pea was aimed at determining the dose-event relationship using various indices in the M1 and M2 generations and isolation of mutants of economic value. Frequency of chlorophyll mutations followed a linear relationship with dose level. A wide spectrum of both lethal and viable mutations was observed in the effective dose range. Among the viable a few mutants affecting the maturity period, grain type and pod number appear to be of practical value. (author)
