Abstract:

The present study was conducted to evaluate the green gram accessions to assess the magnitude of genetic variability and to understand the heritable component of variation for seed yield and its component traits. Estimation of genetic parameters would be useful in developing appropriate breeding and selection strategies. A field trial was laid under a Randomized Block Design (RBD) with three replications; observation was recorded on ten morphological characters (as detailed in material and methods) among the 100 genotypes collected green gram collections. The phenotypic coefficient of variation (PCV) was greater than that of genotypic coefficient of variation (GCV) for all the characters studied thereby indicating the influence of environmental effect on the characters. The high estimates of GCV, heritability and genetic advance were exhibited by plant height, number of primary branches per plant, number of clusters per plant, number of pods per clusters, number of pods per plant and seed yield per plant. Heritability is a measure of possible genetic advancement under selection. High heritability was observed for all the traits under study. High value of heritability coupled with high genetic advance as per cent of mean were recorded for days to 50% flowering, number of primary branches per plant, number of clusters per plant, number of pods per plant, seed yield per plant and these characters were controlled by additive gene effects. Therefore, selection of genotypes based on these traits could bring about desired improvement in yield of green gram cultivars.
