A Study was conducted involving 40 genotypes of blackgram for genetic variability of seed yield and its component traits. The estimates of PCV values were higher than GCV. High estimates of GCV was observed for plant height, crude fiber content and hundred seed weight. Moderate GCV estimates were observed for days to 50% flowering, length of reproductive period and grain yield per plant. Very high heritability was seen for days to 50% flowering, days to maturity, plant height, length of reproductive period, hundred seed weight, protein content and crude fiber content. High genetic advance as per cent of mean was observed for plant height, crude fiber content, hundred seed weight and days to 50% per cent flowering indicating under the control of additive gene effects, may serve as better source for breeding programme to develop high yielding varieties.
