Abstract

An investigation consisted of eight chickpea genotypes viz., RSG-888, CSJD-884, RSG-963, RSG-973, RSG-974, CSJ-515, Avrodhi and HC-5 and crossed in all possible combinations under two environments i.e. timely (E1) and late sown (E2) conditions at Rajasthan Agricultural Research Institute (RARI), SKNAU, Durgapura (Jaipur) Rajasthan during Rabi 2021-22. The objective of present study was to estimate magnitude of different parameters of genetic variability for yield and its components. The observations were recorded for fifteen different yield and its contributing characters and the obtained results indicated that in general the phenotypic coefficient of variance was found to be higher as compared to genotypic coefficient of variance for all studied traits. High heritability with high genetic advance (% mean) was reported for biological yield per plant and seed yield per plant in both the environments while for pods per plant in E1 condition. Thus, the high heritability with high genetic advance confirmed the presence of additive gene effect for all the studied characters and hence can be enhanced through selection.

Conclusion

In order to increase chickpea output, selection must be made in the characteristics, according to analyses of genetic parameters including genotypic coefficient of variation, phenotypic coefficient of variation, heritability, and genetic advance as a per cent of mean. High heritability with high genetic advance was reported for biological yield per plant and seed yield per plant in both the environments while for pods per plant in E1 condition indicating that these characters governed by additive gene action. Hence, selection for genetic improvement in these traits would be effective for increasing seed yield in chickpea crop.
