Abstract:
Blackgram is the third most important legume crop in India and due to very less genetic variability, improvement in yield now requires more emphasis in research for the development of improved varieties. An experiment was conducted with the objective to determine the estimates of genetic parameters for yield and its contributing traits on 40 blackgram genotypes during Rabi/Summer- 2020/21. All the genotypes were sown in three replications by employing randomized complete block design. The observation on different quantitative traits were recorded and the parameters of genetic variability viz. GCV, PCV, heritability and genetic advance were determined. As per ANOVA, all the genotypes differed significantly for all the characters. The highest GCV and PCV was recorded for number of clusters per plant, number of pods per plant, seed yield per plant, number of primary branches per plant, biological yield per plant and plant height. The estimate of heritability was found to be high for characters; number of pods per plant, 100 seed weight, plant height, biological yield per plant height, days to maturity, number of primary branches per plant, number of clusters per plant, number of secondary branches per plant, number of seeds per pod and harvest index. The characters plant height and number of pods per plant exhibited medium genetic advance. High heritability coupled high genetic advance as percent of mean was recorded for number of pods per plant, number of clusters per plant, seed yield per plant, biological yield per plant, number of primary branches per plant and plant height.
