Correlation and Path Analysis of Seed Yield and Yield Contributing Components of Blackgram (Vigna Mungo L. Hepper) Under Rainfed Condition from Andhra Pradesh, India.

ABSTRACT

Correlation coefficient and path analysis studies were carried out with seventeen parents (fourteen lines and three testers) resulting 42 F1 crosses for fifteen yield contributing component characters. The phenotypic and genotypic correlation analysis revealed that seed yield was highly significantly and positively correlated with number of branches, number of clusters, number of pods per plant, number of seeds per plant pod weight, total biomass and also highly significantly and positively correlated among themselves. Path coefficient analysis for seed yield revealed that significant phenotypic and genotypic direct effect with seeds per plant, 100 seed weight, harvest index, pod weight and number of clusters per plant. Hence selection for these characters may be carried out in the field and lab for overall yield improvement in blackgram.
