Abstract

The present experiment of Dolichos bean (Lablab purpureus L.) was laid out during Kharif 2020 at Vegetable Research Farm, RLBCAU, Jhansi, Bundelkhand region of Uttar Pradesh. In this investigation, a total of 21 genotypes of Dolichos bean were sown in a randomized block design with two replications to estimate genetic variability, heritability and genetic advance analysis among genotypes. Observations were recorded on 21 quantitative and qualitative characters. Analysis of variance and mean performance for pod yield and its components revealed significant differences among all the genotypes for all the genotypes for all characters except days to first pod harvesting and dry matter content, indicating the presence of a wide range of variability in studied genotypes. Phenotypic coefficient variation values were slightly greater than genotypic coefficient variation, which revealed little influence of environment on their expression. High estimates of the genotypic and phenotypic coefficient of variation were observed for the characters viz., inflorescence length, number of flowers per inflorescence, number of pods per inflorescence, pod length, vitamin C content, pod yield per plot and 10 pod weights. High heritability coupled with genetic advance as percent of mean was observed for leaf length, flower attributes and pod attributes, except days to first pod harvest, pod width, a width of leaf, days to 50% flowering, number of pod per inflorescence, pod length and chlorophyll content. Based on yield performance, the genotypes, namely RLBDL- S-8 and RLBDL- S-14 were found to be promising genotypes for productive and biochemical traits of Dolichos bean in the Bundelkhand region of Uttar Pradesh.
