Assessment of genetic diversity in Indian common bean germplasm for yield traits

D 2 statistics is a powerful tool for estimating genetic diversity among different genotypes for hybridization programme. On the basis of D2 values, the 169 genotypes were grouped into VIII clusters. Cluster II was the largest consisting of sixty two genotypes viz., KRC-2, K-326, HPK-322(2), HPR-396, VLF-106, K-255, KR-110, KR-249, K-249, VL-63, Palchan Local, Mani Rajma, Palchan kath, AK-40, HPR-80, HPR-24, HPR-38, AK-65, HPR-214, KR-296, HPR-8, KR-56-1, KR-118-1,KRC-16, KR-238, KR-155-3, KR-293, KR-52-2, KR-48-1, HUG-33, K-38, HPR-293, EC-84462, KR-256, AK-4, K-319, KRC12, KR-35, KRC-9, KR-175-1, KR-205, KR-96, KRC-22, Beeses 3 white, KR-171, K296, Premiere, KR-111, KR-53-2, KR-66-2, KR-24, KR-131, KR-240, KR-82, Ribba Local, R-10-457, KR-196, SR-1-6, SR-6-11, Jawala, Baspa. The next largest is clusters IV, followed cluster VII, V, VI, III, I each containing 42, 29, 16,12, 1 respectively. The assessment of genetic diversity helps in reducing the number of breeding lines from the large germplasm. | Assessment of genetic diversity in Indian common bean germplasm for yield traits
