Abstract
AbstractPure dry seeds of variety T9 of Vigna mungo were irradiated by 10, 20 and 30 kR of gamma rays at 33 °C followed by post irradiation treatment with 0.25 % EMS in phosphate buffer (pH 7.0) at 30 ± 1 °C. Vine mutants were isolated from segregating families after 20 kR and 10kR ± EMS treatment. The genetic nature of the mutants was tested by crossing with the wild type. The segregation in F2 proved the mutant to be monogenic recessive. The mutant showed slight improvement in protein content and marked improvement in yield of seeds.
