Genetic Analysis for Seed Yield and Its Yield Components in Chickpea (Cicer arietinum L)

Abstract

Modern plant breeding and agricultural systems has narrowed base for the genetic variability of cultivated chickpea and explore to new sources of variation that might be used in plant breeding programmes. An investigation was undertaken to carried out to assess the genetic variability parameters, correlation and path analysis in 23 chickpea genotypes for 12 quantitative traits in Rabi, 2021-22 season at field experimentation center, Department of Genetics and Plant Breeding, Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Sciences, Uttar Pradesh in Randomized Block Design in three replications. Analysis of variance indicated highly significant differences among the genotypes for all the traits. Considerable variability existed in the genotypes for all the characters studied. These were the genotypes with high mean values in the desirable direction i.e., From the present investigation it is concluded that among 23 genotypes of chickpea, PG – 06102 showed early flowering (66 days), 04 – 01 showed early pod setting (82 days). IPC-97-29 had characters like early maturity (112 days), WCK – 3 showed high plant height (69.7 cm), IPC - 98-12 showed high Number of seeds per plant (68), PG – 06102 is showing high Biomass (19.8 g), and PG – 05 shown high Seed Yield per Plant (12.7 g). Highest GCV were depicted Number of secondary branches, Number of seeds per plant. 100 seed weight (g). The highest Heritability was observed for Number of secondary branches followed by Number of primary branches, Number of seeds per plant, 100 seed weight (g). In the present investigation Seed Yield per Plant per plant showed positive and significant association with Number of Primary Branches, Number of Secondary Branches Number of seeds per plant, Number of pods per plant, biological yield per plant, 100 seed weight (g), Harvest Index (%). Positive direct effect on Seed Yield per Plant per Plant at both genotypic and phenotypic levels with Biomass, Harvest Index, Seed weight. This character should be given due consideration during selection for crop improvement.
