In this study, 416 pear trees were grouped in 28 varieties, and the mean of 20 data were analyzed for each trait. According to the results, 28 varieties were determined and the relationship between them was calculated, the first component had 84.62% of the total variance. Principle component analysis had a fairly good agreement with cluster analysis. Our results related to some flowers and fruit traits differed from previously reported ones.
