Abstract
Barley (Hordeum vulgare L.) germplasm comprising of 133 accessions collected from Pakistan was evaluated for 14 quantitative traits. Significant amount of genetic variation was observed for most of the plant characteristics. All the accessions were grouped into 7 clusters on the basis of morphological similarities. Representative accessions from a cluster of particular group could be chosen for hybridization program. First five principal components having greater than 1 eigenvalue contributed more than 83.40% genetic variation. The PC1 accounted for 33.60% of the total variation. The characters contributing more positively to PC1 were grain yield
