Abstract
One hundred fourteen accessions of rapeseed (Brassica campestris L.) were evaluated at National Agricultural Research Centre, Islamabad, Pakistan using cluster and principal component analyses during 2005 and 2006. Cluster analysis based on fifteen agro-morphological and six seed quality traits, divided 114 accessions into six and five clusters during 2005 and 2006, respectively. The first seven and five PCs with eigenvalues > 1 contributed 74.09% and 66.08% of the variability amongst accessions during 2005 and 2006, respectively. Nine important characters contributed positively to first two PCs during both the years 2005 and 2006.
