Abstract

Forty genotypes of durum wheat were evaluated for eleven characters to quantify the genetic diversity existing them by using Mahalanobis D2 statistic. The genotypes grouped into six clusters. Among the eleven quantitative characters studied, tiller number contributed maximum (10.97%) towards divergence followed by biological yield (10.13%), days to maturity (9.87%), days to heading (9.67%), grains per spike (9.59%) and harvest index (9.10%), Cluster I had minimum days to heading, while cluster V had minimum days to maturity and cluster III had maximum spikelets per spike, grains per spike, grain yield, biological yield and harvest index. The genotypes from cluster III and VI, which have high and low cluster means for majority of the characters are suggested as parents for hybridization.
