Abstract


The primary yield components viz; pods and clusters/plant and pods/cluster were correlated with each other and with yield/plant in all the crosses. Plant height had shown positive and significant correlation in all the wide crosses with pods/plant and clusters/plant, except in G 65 x V. radiata var sublobata while non-significant correla- tion was exhibited in varietal crosses for these pairs of characters Seeds/pod was positively and significantly correlated with yield/plant in all the crosses. Seed size had shown positive and significant correlation with yield/plant in wide crosses, whereas non- significant correlation was exhihibited in the varietal crosses. The heritability estimates for 100 seed weight and pods/plants were high but it was lowest for yield / plant. Pods and yield/plant had high genetic advance in the F. generation.
