Evaluation of Genetic Parameters for Yield and its Attributing Traits in Green gram [Vigna radiata (L.) Wilczek]

Abstract

A study was conducted employing twelve quantitative traits viz., days to  50% flowering, days to maturity, plant height(cm),  number of branches per plant, number  of clusters per  plant, number of  pods per  cluster, pod  length(cm),  number of  seeds   per  pod,  100 seed  weight(g), harvest index, biological yield per plant  and  seed  yield  per plant  (g) on 40 green gram genotypes with the intent to uncover the genetic variability, heritability and genetic advance. Significant variance was found for each characteristic when using simple descriptive statistics. High PCV and GCV estimates was noticed for number of pods per plant, seed yield per plant, number of cluster per plant and number of pods per cluster. Days to 50% flowering, plant height, number of branches per plant, number of clusters per plant, number of pods per plant, pod length, number of seeds per pod, 100 seed weight, biological yield per plant and seed yield per plant showed high heritability with high genetic advancement based on a study of genetic variability, suggesting that additive gene action predominates. It will be beneficial to select for these traits.
