Genetic parameter of early genotypes pigeonpea

Efforts were made to study genetic variability in 13 early pigeonpea genotypes. In general PCV was higher than GCV indicating the effect of environment. The characters No. of pods per plant, secondary branches/plant, primary branches/plant, days to maturity showed higher genotypic and phenotypic coefficient of variation. High heritability recorded No. of pods/plant, days to 50% flowering, 100-seed weight and plant height. High genetic variance and high genetic advance as percent of mean shown by the characters No. of pods/plant, secondary branches/plant, 100-seed weight, days to 50% flowering, days to maturity. Heritability in broad sense was moderate indicating influence of moisture stress on these traits. However, high genetic advance as percent of mean indicating additive gene effects governing the traits providing ample scope of improvement.
