ABSTRACT
The research was conducted to investigate the correlations among agronomic and yield-related characters in M3 generation of Bambara groundnut genotype SB-42 and to verify their direct and indirect effects which will be used for the selection for seed yield per plant. The 64 M3 mutants were raised during kharif season of the year 2014-15. Seed yield per plant had highly significant and positive correlation with the pod yield per plant with pod yield per plant (0.935**), number of pods per plant (0.824**), plant spread (0.675**), plant height (0.681**), plant dry weight (0.476**) and number of branches per plant (0.314*). Path analysis revealed that pod yield per plant (1.0596), shelling percentage (0.3644), number of pods per plant (0.0626), 100 seed weight (0.0461), plant spread (0.0243) and plant dry weight (0.0138) had high of direct effect positive on seed yield. Such characters will be useful in selection programme for increasing yield. Among all the characters pod yield had highest indirect effect on seed yield. Those characters which showed significant positive correlation and exerted direct positive effect on the yield like pod yield per plant, numbers of pods per plant, plant spread and plant dry weight could be selected for making improvement in yield.
Key words: Vigna subterranea, EMS, Yield Components, Correlation, Path Analysis.
