Abstract

Variability, heritability and genetic advance were estimated for sixteen characters in twenty blackgram (Urd) types. phenotypic and genotypic coefficient of variation for dry leaf weight was high followed by seed yield and leaf area. Genetic advance was high for seed yield followed by dry leaf weight. Seed yield per plant showed significant positive correlation with all the characters except number of primary branches, specific leaf weight and protein per cent. path coefficient analysis revealed plant height and primary leaf area had higher positive direct effect on seed yield and 100 seed weight recorded highest negative direct effect on seed yield.
