The objective of study was to assess genetic diversity in exotic germplasm (8th EBWYT) of wheat (Triticum aestivum L.) based on cluster analysis and principle component analysis (PCA). There was a significant relationship among the studied traits i.e. days to heating, plant height, spike length, canopy temperature and grain yield per plant. A positive significant correlation was observed between spike length and number of spikelet per spike while a negative significant correlation was assessed between canopy temperature and thousand kernel weight. Out of seven, three PCA’s axes inhibited more than one Eigen value but the level of dissimilarity was high which indicated that the germplasm was with broad genetic base. Cluster analysis expressed high level of diversity because two main groups were observed, one with 14 and the other with 16 genotypes.
