Abstract

With an aim of establishing selection criteria for breeding high yielding varieties offering high nutritional content and good root architecture, association analysis was performed among 106 chickpea genotypes including 8 checks for eighteen yield, yield attributing, root and nutritional traits during Rabi 2020-21 and Rabi 2021-22. Simple correlation and path analysis based on pooled data of two seasons suggested that while exercising selection index due weightage given to the traits viz., biological yield, harvest index for improving seed yield per plant and 100 seed weight will be rewarding for simultaneous improvement in these traits. Selection of genotypes with high protein content, larger root length and moderate seed size will be helpful in developing high yielding high protein content varieties with good root architecture. Whereas, direct selection of plant height will be rewarding for developing machine harvestable varieties by improving height of 1st pod.

Conclusion

Correlation and path analysis suggested selection of traits viz., biological yield and harvest index for seed yield per plant, selection of plant height for height of 1st pod and biological yield and seed yield per plant for 100 seed weight will be rewarding for simultaneous improvement in these traits in breeding programmes. Also selection of genotypes with high protein content, larger root length, root volume and moderate seed size will be helpful in developing high yielding high protein content varieties with good root architecture. Hence, it is suggested that while exercising selection index due weightage should be given to these traits.
