ABSTRACT
Genetic variability, correlation and path coefficient in 27 promising lines of black gram were studied to find important traits contributing towards grain yield. Genetic variability study revealed that the characters plant height, number of pods, pod weight and grain yield exhibited high genotypic variance and high heritability coupled with high genetic advance which indicates the presence of high additive gene effects suggesting direct selection for these traits would be fruitful. The correlation coefficient of grain yield was highly positive and significant with number of branches plant1, number of pods plant1, pod weight plant1 at genotypic and phenotypic level. Path analysis revealed that pod weight followed by number of pods plant-1, length of pod, number of branches plant-1 and number of seed per pod exhibited high direct effects in desirable direction.
