Study on Genetic Divergence Using D2 Analysis in Greengram (Vigna radiata (L.) Wilczek)

The purpose of the present study was to evaluate genetic variability parameters such as genotypic coefficient variation (GCV), phenotypic (PCV), heritability, advance, well divergence and identify suitable parents for among 53 different Greengram genotypes, including one check variety. experiment conducted during kharif 2022-2023 at experimental farm Department Genetics Plant Breeding, Naini Agricultural Institute, Sam Higginbottom University Agriculture, Technology, Sciences in Prayagraj, Uttar Pradesh. A randomized block design with three replications employed study. Thirteen characteristics were observed recorded, which include: days 50% flowering, pod initiation, maturity, plant height, number primary branches per plant, clusters length, seeds pod, biological yield, harvest index, seed index yield plant. IPM-2-14 exhibited highest mean performance terms followed by MGG-385, all genotypes. PCV values consistently higher than corresponding GCV traits, indicating influence environmental factors on trait expression. pods recorded values. both high heritability advance. genotypes categorized into six through D2 analysis. Cluster I had maximum intra cluster distance IV, inter between III VI. VI height. Percentage contribution characters towards divergence.
