Abstract

Seeds of black gram varieties COBG 301, PDU I and their hybrid COBG 301 x PDU 1 were treated with gamma rays in order to obtain high yield. The treated seeds of three different genotypes showed negative shift for Mi generation and positive shift for M2 and M3 generations. The seed yield increased in M2 generation at higher doses while lower doses in My generation.

Keywords: Black gram, Gamma Rays, Mutagenesis, Genetic Advance.
