摘要

The magnitude of variability in Pongamia pinnata germplasm collected from different parts of Haryana was assessed. In total 40 plus trees based on morphometric characters were selected. Maximum values for seed length (23.18 mm), 100-pod weight (400.80 g) and 100-seed weight (185.37 g) were observed in accession 527962. Accession no. 524747 showed maximum oil content (43.06%) and pod length (55.47 mm). Genetic divergence indicated considerable diversity among 40 accessions. Eight clusters were obtained based on non-hierarchical Euclidian cluster analysis. Cluster I exhibited maximum intra cluster distance (5.47) whereas, maximum inter cluster distance was observed between cluster VI and VIII (9.251). Cluster IV recorded highest value for seed length (24.17), breadth (16.10), thickness (9.93), 100-seed weight (186.80) and 100-pod weight (403.93). Cluster VI recorded the highest value for pod length (57.03), pod breadth (25.37) and oil content (44.07). Thus crosses involving clusters IV and VI may be suggested alongwith further selection for the overall improvement of species.
