GENETIC VARIABILITY, CORRELATION AND PATH ANALYSIS IN BLACKGRAM

Abstract

Fifteen parents and 50 hybrids were evaluated at two locations. Variability. correlation and path coefficients were worked out on seven characters. High PCV and GCV were observed for seed yield and plant height. High heritability coupled with high genetic advance was observed for plant height, clusters per plant. pods per plant and seed yield per plant. Branches per plant, clusters per plant and pods per plant showed significant positive correlation with seed yield. Protein content was negatively correlated with seed yields. Pods per plant exerted positive direct effect on yield.

Keywords: Blackgram. Variability, Correlation, Path analysis
