Dry bean population with white circular seed types growing in the İspir province of Erzurum is known by delicious taste and attracts considerable attention at nationwide. Forty bean lines obtained from İspir bean population were taken for characterization, selection and pre-yield trials a year ago. Fifteen of the 40 lines were promising and constituted the material of this study. Promising lines were taken into experiments with two control varieties (Elkoca-05 and Aras-98) in terms of yield, yield components and resistance to diseases, in three randomized complete blocks in the growing season of 2015. The results showed that there were significant differences among the lines in terms of yield and yield components. The lines were subjected to cluster analysis in terms of 14 quantitative parameters and it was determined that the lines were clustered into two main groups. While the first group included 10 İspir bean lines, 5 İspir bean lines (Registration number: 6, 17, 32, 40 and 69) and standard varieties were clustered in the second group. The mean values of the groups revealed that the genotypes in the second group matured on average one week earlier, and that the genotypes in this group were superior in terms of grain yield and many yield components. As a result of the study, İspir bean lines 6, 32, 40 and 69, which show superiority in terms of yield, yield components and resistance to diseases, were decided to transfer to the regional yield experiments.
