Abstract:
The current empirical study on "Genetic divergence in green gram (Vigna radiata (L.) R. Wilczek)" was conceded to assess genetic divergence in 72 genotypes of green gram. The experiment was conducted in RBD with 3 replications at the Pluses Research Station, J.A.U., Junagadh, during kharif 2021-22. On 11 traits, observations were recorded. Genetic diversity studies, using Mahalanobis's D² statistics, indicated existence of significant diversity among 72 green gram genotypes that were grouped into 12 clusters. Among 12 clusters formed, cluster II having highest number of genotypes (20) followed by cluster I (18) and cluster VI (12). On the other hand, cluster III, cluster IV, cluster VII, cluster VIII, cluster IX, cluster XI and cluster XII are solitary clusters. The intra-cluster distance was highest in cluster X (7.81) and lowest in cluster I (5.55). The maximum inter-cluster distance was found between cluster IV and XII (D = 19.16) followed by cluster XI and XII (D = 18.01), cluster III and XII (D = 16.59), cluster II and XII (D = 16.22), cluster IV and V (D = 15.89) and cluster VI and XII (D = 15.81). It was also revealed that the grain yield per plant (26.49%) contributed maximum towards the total divergence followed by 100-seeds weight (25.82%), number of pods per plant (11.15%), length of pod (9.04%), plant height (8.33%) and number of clusters per plant (7.71%).
