Abstract

Genetic divergence of 29 exotic walnut cultivars introduced from abroad and 25 local selections from seedling
population was studied. The analysis of variance revealed significant differences among accessions for each character under
study. Based on Mahalanobis D2 values the accessions were grouped into eight clusters. Cluster I had a maximum of
12 accessions followed by cluster II with 11 accessions. The mean intra and inter cluster distance (D) revealed that cluster
VII had the highest intra cluster distance (2.171), while the inter cluster distance was the greatest between cluster II and
IV (10.528). Characters like plant height, trunk girth, plant spread, plant volume, leaf length, leaf width and number of
leaflets contributed the most to total divergence.
