Abstract:

Studies on thirty six blackgram genotypes for the association and path analysis, revealed that, the genotypic correlations were in general higher than the phenotypic correlations and thus suggested that the observed relationships among the characters were due to genetic causes. The traits, number of clusters per plant, number of pods per plant, number of seeds per pod and 100 seed weight were found to possess positive significant association in desirable direction with grain yield per plant either at both genotypic and phenotypic levels. Further, it was also observed that days to 50% flowering and days to maturity were found to be negative and significantly correlated with grain yield per plant. Path analysis showed the true relationship of plant height, number of pods per plant, pod length, number of seeds per pod and 100 seed weight by establishing significant positive association and positive direct effect on grain yield per plant, whereas days to maturity showed true relationship by establishing significant negative association and negative direct effect on grain yield per plant, the residual effect at phenotypic level was 0.203 indicating that the characters included in the present investigation are contributing more than 79.70 per cent of variability pertaining the dependent variable i.e., grain yield per plant.
