Abstract
The present experiment was carried out at field experimental centre site of the Genetics and Plant Breeding, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj to study about Genetic Variability, Correlation And Path Co-Efficient Analysis in thirty one chickpea germplasm during Rabi-2020-21. The analysis of variance revealed significant differences among the genotypes for all the quantitative characters under the study, indicating high amount of variability present in the chickpea germplasm. The values of PCV were found greater than GCV for all the traits studied indicating environmental factors influencing the characters. High PCV and GCV were observed for Biological Yield Per Plant (28.075 and 29.334) followed by Seed Yield Per Plant (23.732 and 26.369), Number Of Seeds Per Plant (24.903 and 27.643), Number Of Pods Per Plant (24.519 and 28.234) indicated large extent of Genetic Variability for these traits in the material. High Heritability were recorded by Biological Yield Per Plant (91.6), Days To 50% Pod Setting(94.1), Seed Yield Per Plant(81), Number Of Secondary Branches Per Plant(88.5), Number Of Seeds Per Plant(81.2), Number Of Pods Per Plant (75.4). High Heritability along with high Genetic Advance was observed for the traits, viz., Days To 50% Pod Setting, Number Of Seeds Per Seeds Per Plant, Number Of Pods Per Plant, Biological Yield Per Plant indicated that the characters were mostly governed by additive gene effects. So direct selection of these characters based on Phenotypic expression by simple selection method would be effective due to accumulation of more additive genes leading to further improvement. The present study revealed that Seed Yield Per Plant was Positively and significantly Correlated with 100-Seed weight (g), Harvest Index Per Plant (%), Biological Yield Per Plant(G), Number Of Pods Per Plant, Number Of Seeds Per Plant where as significant and negatively Correlated with Days To 50% Pod Setting respectively. Path Co-efficient analysis revealed that traits, viz., number of seeds per plant, number of pods per plant, 100-seed weight(g), harvest index(%), and biological yield per plant(g) showing the direct positive effect on Seed Yield Per Plant(g) at Phenotypic and Genotypic level had given the highest contribution of Seed Yield Per Plant. So the utmost importance should be given to these traits during the selection for Seed Yield improvement in Chickpea.
