Abstract:
An experiment was carried out to estimate the genetic parameters like variability, heritability and correlation studies for eleven quantitative characters viz., days to 50% flowering, days to maturity, plant height, number of primary branches plant-1, number of pods plant-1, pod length, number of seeds pod-1, biological yield plant-1, test weight, harvest index, and grain yield plant-1 in 40 genotypes of Black gram (Vigna mungo (L.) Hepper). High phenotypic coefficient of variance (PCV) and genotypic coefficient of variance (GCV) were observed for all the characters studied. The phenotypic coefficient of variance was higher in magnitude than the respective genotypic coefficient of variance for all the characters indicating the important role of environment in the expression of characters. High heritability coupled with high genetic advance was observed for plant height only indicating the heritability is due to additive gene action and simple selection for this trait. Hence, yield studies revealed that, grain yield plant-1shows significant positive correlation with biological yield per plant, number of pods per plant, number of seeds per pod, test weight, plant height, number of primary branches per plant and pod length both at phenotypic and genotypic level. Path analysis studies revealed that biological yield per plant, number of pods per plant, number of seeds per pod, test weight, plant height, number of primary branches per plant and pod length both at phenotypic and genotypic level.
