One hundred thirty nine soybean genotypes were evaluated for yield and yield associated traits at National Agricultural Research Centre, Islamabad. The traits viz., days to maturity, plant height at maturity, number of branches per plant, number of filled pods per plant, number of unfilled pods per plant, 100-seed weight, oil content, grain yield per plant, biological yield per plant and harvest index were studied. The results revealed significant differences among genotypes for all studied traits. Cluster analysis based on these traits, 139 genotypes were divided into five clusters. Cluster I showed maximum number of filled pods per plant, 100-seed weight, grain yield per plant, biological yield and harvest index. Cluster II showed least oil content, grain yield per plant and harvest index. Cluster III showed maximum plant height and number of branches per plant. Cluster IV comprised of accessions having high oil content and least number of unfilled pods per plant while ear
