Abstract:
Sixty pigeonpea genotypes were evaluated at International Crops Research Institute for the Semi-Arid Tropics during kharif 2021-22 for genetic parameters. Genetic variance (σ2ݐº) was recorded higher than environmental variance for all the traits viz., days to 50 percent flowering (DTF), plant height (PltH) and seed protein content (SPC). Broad-sense heritability (H2) estimates were highest for DTF followed by PltH. The range of genotypic coefficient of variation (GCV) observed was 6.43 to 10.42 percent for the traits under study indicating the extent of variability present among the pigeonpea genotypes. Moderate PCV and GCV was observed for the PltH and low phenotypic coefficient of variation (PCV) and GCV was observed for the traits DTF and SPC. High H2 associated with high genetic advance as h of mean (GAM) was observed for PltH indicating that it was controlled by additive gene action and selection is advisable.
