Abstract:

Genetic variability, heritability, genetic advance of yield attributing characters and their association among them on yield are paramount importance for crop improvement. Correlation and path analysis are important biometrical tools for getting information regarding inter-relationship among various traits used in selection programme. In the present study, twelve yield and yield related parameters have been studied in 374 diverse genotypes of greengram. The genotypes differed significantly for all characters under study except for plant height, number of branches per plant and test weight. Number of clusters per plant, number of pods per plant and number of seeds per pod showed high GCV and PCV values. Heritability estimates in broad sense and genetic advance were high for all the characters except for test weight indicating that estimates reveals the heritable portion of variability. Association analysis indicated that, seed yield per plant showed significant positive correlation with pod yield per plant followed by number of pods per plant, number of clusters per plant and threshing percentage. Among the characters studied pod yield per plant had very high positive direct effect followed by high positive direct effect of number of pods per plant, threshing percentage and number of clusters per plant on seed yield per plant. So, more emphasis should be given to these characters in indirect selection for seed yield improvement in greengram.
