The study titled “Investigation of genetic variability in pigeon pea for yield and its attributing traits (Cajanus cajan L. Millsp.)" took place at the Research and Education farm, Botany Department, College of Agriculture, Dapoli, during the Kharif season of 2022. Across all 14 traits examined, the PCV(phenotypic coefficient of variation) surpassed the GCV (genotypic coefficient of variation) in magnitude. Notably, per plot seed yield, % pod borer damage, plant height exhibited high PCV. Conversely, per plot seed yield, % pod borer damage, pods / plant displayed high GCV.

Appreciable heritability estimates were noted across all evaluated traits, with the highest heritability observed for harvest index, test weight, and days to fifty% flowering. Genetic advance was most pronounced in per plot seed yield, followed by % pod borer damage. Moreover, % pod borer damage, per plot seed yield (g), seed yield / plant (g) showcased comparatively higher estimates of genetic advance as a percentage of mean.

In terms of performance, the genotypes LOCAL-7, IPAWD-36, and IPAWD-25 emerged as top performers, demonstrating the highest seed yield / plant and maximum yield-related characteristics. These genotypes hold promise as valuable genetic resources for future breeding programs.
