Cite article:- Rambabu* E., Reddy Ravinder K., Kamala V., Saidaiah P., Pandravada S.R. (2016). Genetic divergence for quality, yield and yield components in Yardlong bean[Vigna unguiculata (L.) Walp. ssp.sesquipedalis Verdc.] . Legume Research. 39(6): 900-904. doi: 10.18805/lr.v0iOF.11187.

Genetic divergence among 41 commercial Yardlong bean genotypes was investigated to select the parents for hybridization using Mahalanobis D2 statistics. The genotypes fall into seven clusters. Cluster VI had the maximum (12) and cluster VII had the minimum (1) number of genotypes. The intra cluster D2 value ranged from 0.00 (Cluster II, III, VI, VII) to 121.69 (Cluster V). The cluster V had the maximum D2 value (121.692) followed by Cluster IV (77.305) and Cluster I (46.391). The inter cluster D2 values of the seven clusters revealed that highest inter cluster generalized distance (607.945) was between cluster V and cluster VII, while the lowest (15.917) was between cluster II and cluster III. Regarding relative contribution of different traits towards divergence, pod length (48.66%) contributed maximum followed by pod ascorbic acid content (20.00%), pod girth (12.20%) and 100 seed weight (12.20%) among Yardlong bean genotypes. Based on genetic distances and clustering pattern, the most divergent genotypes identified are IC-582859, NSJ-362, IC-582850, IC-582872, IC-582851 and IC-582829 from III, V, and VI clusters could be used as best parents on crop improvement programme to produce desirable segregants for yield and yield attributes in Yardlong bean.
