Abstract

Assessment of the genotypic and phenotypic correlation estimated from pooled data over 4 environments regarding yield and yield attributes of 60 genotypes of rice bean [Vigna umbellata (Thunb) Ohvi and Ohashi) revealed that plant height, days to initiation of f1owelng, days to 50 per cent flowering, peduncles/plant, pods/plant and grains/plant showed consistently positive and significant correlation with grain yield in all 4 environment and on pooled basis. At phenotypic level yield did not show significant association with pods/peduncle, grains/pod, pod length and 100 grain weight on pooled basis. Thus, plant height, days to initiation of flowering, days to 50 per cent flowering, peduncles/plant, pods/plant and grains/plant are the major yield attributes and therefore deserve adequate consideration while constructing selection Indices in rice bean.
