Correlation and path analysis for yield and yield contributing traits in black gram [Vigna mungo (L) Hopper.]

Abstract

Tweenty one Black Gram (Vigna mungo (L) Hopper) genotypes were evacuated for the estimation of genetic variability parameters, correlation coefficient, path analysis, heritability and genetic advance. The genotypes differed significantly for all the characters. Higher GCV and PCV was observed for the seed index. High heritability coupled with genetic advance as percent of mean shown by harvest index indicating the impact of additve and significant correlation along with positive direct effect on grain yield. Therefore selection based on this component traits would results improvement in grain yield of Black Gram.

Genetic diversity analysis in blackgram [Vigna mungo (L.) Hepper]

“…From the intra correlation studies, seed yield per plant had a significant and positive association of the studied genotypes in black gram with trait viz., the number of clusters per plant (0.348) and the number of pods per plant (0.429). A similar result was obtained by Kumar et al (2014) and Kanimozhi et al (2009). Days to 50% flowering had a positive and significant association with plant height (0.307); plant height had a positive and significant association with hundred seed weight (0.225) and protein content (0.210) and the number of clusters per plant had a positive and significant association with the number of pods per plant…”
