| Abstract: | 【Objective】 In order to study the similarity and genetic diversity of fruit characters among pear breeding materials, 15 Xinjiang pear varieties were compared and evaluated for their fruit characters, which provided reference for rational evaluation and utilization of Xinjiang Pear Germplasm resources. 【Methods】 Using the method of variance analysis and Q-cluster to compare and classify the pear fruit, and based on the characteristics of the fruit, principal component analysis was carried out. 【Results】 (1) The variety diversity of Xinjiang local pear was rich, the variation coefficient of each quantitative character ranged from 8.83% to 80.75%, the variation coefficient of fruit shape index was the smallest, and the variation range of stone cell content was the largest, which was mainly reflected in the different classification of different parts. (2) The order of fruit point density and fruit hardness was: calyx > stalk > carcass. (3) The 15 varieties were divided into four groups by Q-cluster, the same group was more close to the overall characteristics of other groups, and gathered according to the trend of the region. (4) Four principal components were extracted when the eigenvalue was more than 1, and the cumulative variance contribution rate was 85.91%. The top three of the evaluation results were Huocheng Donghuangli, Yili Jujuli and Kuike Amute. 【Conclusion】 In the cluster analysis, Lvli is clustered into one group, which has unique characteristics in fruit shape and quality, and has high content of soluble solids, so it can be used as a special breeding material; Heisuanli and Huocheng Donghuangli can be considered as breeding parents to improve the single fruit quality; Korla Huangsuanli has high hardness, which can be used for the research of transportation and storage tolerance; The juice content of Kuike Amute can be used as parents of high quality varieties for juicing. According to the comprehensive data analysis, Huocheng Donghuangli, Yili Jujuli and Kuike Amute have good fruit characters, which have important application value for pear germplasm innovation and parent selection of cross breeding. |
