Abstract

Single treatments of gamma irradiation at 30 krad and EMS at 40 mM in TMV-9 and combination (20 krad+40mM) treatment in Ah. 7911 have resulted in the isolation of 40 mutant plants in M, showing superior yield and morphological similarity to parents. When they were tested in M. generation, five out of 40 lines gave significant higher yield than their respective parents. Number of mature pods contributed to higher Vield. Hundred kernel weight remained unaltered due to mutagenic treatments which resulted in increased number of pods and superior yield in mutant lines.
