Gamma rays to identify YMV resistant and determinate plant type. The individual plant and plant-row selections were made in M2, M3 and M4 generation of MDU 1 and VBN (Bg) 4. Mutant population was screened for YMV resistance, pods protruding up above the canopy, early maturity, and purple pigmentation on plant. The investigation revealed that ACM16–30, ACM-16-29, ACM-6-17 and ACM-16-14 mutant lines were found to be as ideal mutant lines for further improvement programme. The mutants line had YMV resistance, purple pigmentation on leaf, hypocotyls, stem and pod along with pods protruding up above the canopy, good batter quality and bold seeded type.
