Pentaphyllous mutants in black gram were isolated in M2 generation of a segregating family, irradiated at 20kR. The genetic nature of mutants was tested by hybridizing with controls, and chi-square tests applied to the F2 population, proved it to be a monogenic recessive. The pentaphyllous mutant had a greater number of pods and leaves per plant and larger and more root nodules. It also showed improved nutritional value with increased seed protein percentage and no increase in TIA (trypsin inhibitor activity).
