Abstract:
The Purpose of this study was to determine at the Field Experiment Research Center, “Department of Genetics and Plant Breeding, Sam Higginbottom University of Agricultural Technology and Sciences, Prayagaraj”, during Kharif 2019 in a randomized, three-repetition block design to gain insight into the nature and range of genetic parameters and its use in developing for superior pigeonpea genotypes [Cajanus cajan (L.) Millsp.]. The genetic parameters examined are genotypic and phenotypic variation, genotypic and phenotypic coefficient of variation, heritability (h2) and genetic advance. In addition, these parameters, correlation coefficients and path analysis for seed yield and the properties of its components were also examined in 12 different long-term experienced pigeonpea genotypes. Results showed that the genotypes of all traits studied showed significant variability, and the analysis of variance showed that there were highly significant differences among the 12 pigeon pea genotypes of the 14 quantitative traits studied. It can be concluded from the current investigation that among the 12 pigeon pea genotypes based on average yield, 912, 901, 902, and 907 were found to be superior and showed the maximum seed yield. Among these 12 genotypes, they were found to provide the best results for 912. The maximum genotype and phenotypic variation of biological/plant yield, plant height and harvest index were recorded. Record the maximum GCV and PCV of each plant, the number of pods per plant, and the weight of each pod. The high heritability of seed yield, plant height, harvest index, number of pods per plant and seed yield per plant were recorded for each plot. High heritability and high genetic progress are recorded as a percentage of the average seed yield for each plot.
