Multivariate analysis was carried out to assess genetic diversity among twenty eight exotic and endogenous barley (Hordeum vulgare L.) genotypes at Bangladesh Agricultural Research Institute (BARI) during rabi 2007-08. Mahalanobis’ generalized distance (D2) analysis was used to group the barley genotypes. Among the genotypes, maximum variation was observed for grains per spike and tiller number/plant. Considering the mean values, the genotypes were grouped into five clusters. Among them, cluster IV and V contained 8 genotypes each, whereas, cluster I, II and III contained 4 genotypes each. Cluster V and II had higher mean values for number of grains/spike, 1000-grain weight and yield/plant. On the other hand, genotypes of cluster I were the earliest with lower mean values for number of grains/spike, 1000-grain weight and yield/plant but had the highest value for tillers/plant. Therefore, genotypes EMBSN-04-06, EMBSN-05-06, EMBSN-09-06, EMBSN-34-06, BHL-10, BHL-15, BHL-18, BB-1, BB-2, BB-4, BB-5 and BB-6 of the two clusters (I and V) might be selected for cross breeding programme.
