Abstract: The present investigation was conducted to examine the 20 Pigeon pea genotypes along with 2 checks to study the genetic parameters, correlation and genetic diversity. The experiment was carried out in main experimental station of Agricultural Research Farm, Rama University (U.P), Mandhana, Kanpur during Kharif Season, 2023-24 in Randomized Block Design (RBD) with three replications. Analysis of variance showed highly significant differences among 20 Pigeon pea genotypes for 12 characters studied. On the basis of mean performance, Analysis of variance showed highly significant differences among 20 Pigeon pea genotypes for 12 characters studied. The results showed that, phenotypic coefficient of variation (PCV) was greater in magnitude than the respective genotypic coefficient of variation (GCV). The characters viz., seed yield per plant (28.33), biological yield per plant (23.77), showed highest phenotypic coefficient of variation. Moderate phenotypic coefficient of variation was observed for total pods per plant (19.12), test weight (13.36%), number of branches per plant (13.35%), harvest index (10.11%). The lowest magnitude of phenotypic coefficient of variation was reported in days to 75% maturity (4.26%) followed by secondary branches per plant (4.92%), pod length (6.19%), days to 50% flowering (6.29) total seeds per pod (6.74%) and plant height (6.90%). The amount of genetic variation present in the 20 genotypes was worked out in terms of genotypic coefficient of variation (GCV). The highest genotypic coefficient of variation was recorded in percent by seed yield per plant (25.27%) followed by biological yield per plant (21.93%).The moderate GCV was observed in traits, viz., number of pods per plant(17.26%), seed index (12.51%), primary branches per plant (11.53%), whereas lowest GCV was seen in harvest index(9.74),days to 50% flowering (5.88),plant height (5.23%), number of seeds per pod (4.38%), days to maturity (3.84%), pod length (2.35%), secondary branches per plant (1.27%).
