Abstract:: One-year-crossbred seedlings from 6 full-sib families of Korla fragrant pear were used as materials，and plant height，basal diameter，leaf length and width，leaf area and perimeter were measured for analyzing the characteristic differences within and among 6 full-sib families.The results showed that the characters of plant and leaf from 6 full-sib families had segregated to various degrees.The character segregation rank of character from different plant parts as follow：leaf area>leaf perimeter>basal diameter>leaf length>plant height>leaf width.The pollination combination of Pingxiang pear and Korla fragrant pear showed the best in seedling growth.The character segregation degree of Wanxiang pear×Korla fragrant pear and Korla fragrant pear×Pingxiang pear were the largest among 6 pollination combinations.Effect of female parent on plant and leaf characters were bigger than male parent，and male parent mainly effect on leaf characters.So leaf area could be one of the important reference index in the early identification of crossbred seedlings.
