摘　　要：【目的】摸清我国不同产地下圆黄梨的果实品质表现,以及探索圆黄梨在不同产地间的果实品质差异,为圆黄梨的适地适栽提供理论依据。【方法】以19个不同地区的圆黄梨的果实为试验材料,测定11项果实品质指标。同时,应用极值归一化法对各项果实品质数据进行转化后,进行主成分分析和聚类分析,根据主成分结果结合对应的权重,计算综合得分排名。【结果】归一化的数据经主成分分析后,得到4个主成分,累计贡献率为83.490%,河南宁陵、山东费县等地综合得分排名较高;采用系统聚类分析后,在遗传距离为16时,19个产地的圆黄梨果实品质主要有5种类型。【结论】摸清了圆黄梨在我国不同地区的引种表现以及不同产地间的果实品质差异,对于确定圆黄梨在我国的最佳生态区有一定的参考意义。【Objective】Wonhwang pear has good fruit quality and high economic value,and has a large planting area in China.However,there has been limited investigation of fruit quality in different regions in China.There are great differences in climate and ecological environment among different regions,which may have impact on fruit quality.To find out the fruit quality of Xianyuan pear from different regions in China,and to explore the fruit quality differences of Wonhwang pear in different regions,we carried out this study.【Methods】The fruits of Wonhwang pears from 19 different areas were used as the experimental materials.Eleven fruit quality indexes including as single fruit weight,shape index,soluble solid content,titratable acid content,soluble sugar content,sugar to acid ratio,soluble solid to acid ratio,peel hardness,pulp hardness,vitamin C content and stone cell content were determined.SPSS was used for fruit quality data analysis.At the same time,the extremum normalization method was applied to transform the fruit quality data,and principal component analysis and cluster analysis were conducted.Comprehensive score ranking was made according to the principal component results combined with the corresponding weights.【Results】Fruit shape index ranged from 0.809 to 1.067 and fruit weight from 208.67 to 457.00 g.The highest fruit weight was obtained in Ningling of Henan Province.The soluble solid content ranged from 11.70%to 15.93%,and the highest soluble solid content was obtained in Funan of Anhui Province.Titratable acid content ranged from 0.18%to 0.42%,and the highest titratable acid content was found in Zhijiang of Hubei Province.Total soluble sugar content was in the range from 5.01%to 12.90%,and the highest was obtained in Jinan of Shandong Province.The ratio of sugar to acid ranged from 14.44 to 70.36,and the highest was found in samples from Jinan of Shandong Province.The ratio of soluble solid to acid varied from 29.92 to 80.18,and the highest was obtained in samples from Jinan of Shandong Provin
