Abstract

The present study was carried out to assess the genetic variability and character association amongst nineteen farmers' chickpea varieties that were examined during Rabi 2019-2020 under RBD with three replications. ANOVA showed highly significant differences for all of the characters studied at 1% level of significance except days to maturity. For majority of the characters, PCV was somewhat greater than GCV, indicating that character expression is mostly controlled by genotypes, with just a little contribution of environment. The characters viz., number of pods per plant, number of primary branches per plant, number of secondary branches per plant, biological yield per plant, seed index, harvest index, and seed yield per plant all had high heritability coupled with high GAM, indicating that these characters are driven by additive gene action. Biological yield per plant and harvest index revealed a significant positive association and had a direct effect on seed yield. As a result, the

Conclusion

The analysis of variance for all the varieties revealed significant differences for all of the traits under investigation. Based on mean performance, the farmers' chickpea varieties Tiwari Chana-2, followed by CRCB-447, were identified to be the most propitious for seed yield per plant and other traits. characters such as the number of pods per plant, number of primary branches per plant, and the number of secondary branches per plant had high GCV, PCV, and Heritability, indicating that the environment had little impact on the expression of these characters. Number of pods per plant, number of primary branches per plant, number of secondary branches per plant, biological yield per plant, seed index, harvest index, and seed yield per plant, all had high heritability coupled with high GAM, showing that these characters are driven by additive gene action. Characters such as biological yield per plant and harvest index shown a significant positive correlation and had a direct influence on
