Assessment of gamma induced genetic divergence in M₂ generation of soybean

Genetic diversity in twenty four M₂ treatments resulted from 10, 20, 30, 40 and 50 kR gamma irradiated soybean varieties was studied. These treatments were grouped into six different clusters. Genetic diversity was independent of varieties and doses of gamma rays. Sufficient amount of variability due to induced mutations for different polygenic characters over the parent variety was observed in M₂ families. It formed basis for restricted desirable selections.
