Litchi (Litchi chinensis Sonn.) fruit is generally recognized as “Queen of the fruits”. It is highly prized for its excellent quality, pleasant flavour, juicy pulp and attractive red peel colour. Despite of its commercial importance, the study on breeding aspect particularly genetic improvement of available germplasm is lacking. The current study on the D2-based divergence analysis using Euclidian and Tocher’s methods indicated the existence of appreciable amount of genetic diversity in the eighteen hybrids of litchi. Test hybrids were grouped into five clusters based on different quantitative traits using above methods with variable number of entries in each cluster. In Euclidian’s method, cluster 1 had maximum number of hybrids (7) followed by cluster 3 (4), 2 (3), 4 (2) and 5 (2), while in Tocher’s method, cluster I had utmost number of hybrids (10), while the cluster III, IV and V contained the least (1). Maximum inter cluster distance indicate that hybrids falling in these clusters had wide diversity and can be used for improvement programme to get better recombinants in the segregating generations. The hybrids H-400, H-515 and H-711 recognized good for genetic improvement in litchi hybrids for commercial purposes.
