Abstract：【Objective】Explore thediferences infruitqualityof‘XinliNo.7’indifferent productionareas，andprovide theoretical basis for the optimal layout of‘Xinli No.7' planting areas.【Method】With 26 pear orchards in 5 production areasof‘XinliNo.7'as the testmaterial，todetermine thefruitappearancequality，texturequalityandnutritionalquality ofatotalof22 indicators，usinganalysisofvariance，corelationanalysisand principalcomponentanalysis toanalyse the differences inthequalityof the‘XinliNo.7'fruit indiferent productionareas，andevaluatethecomprehensivequality ofthefruit indiferent productionareas.【Result】Thefruitqualitytraitsof‘XinliNo.7'varied greatlyamongdiferent production areas.Intermsof the appearance qualityof ‘XinliNo.7，the single fruit mass （257.48 g）of thefruit in Gansu Waslarger，and the peel thickness （54.53μm） ofthefruitinXinjiangwasthinner.Thebrightnessand red-greenvalue and yellow-blue value offruits in Xinjiang and Gansu were higher. In terms of texturequality，the fruit hardness （6.87N） in Shanxi was higher，and the fruit gumminessand chewiness were significantly higher thanthose in Gansu.Interms of fruitnutritioalqualitythesolublesolidmassfraction，proteinmassfraction，solublesugarmassfractiontotaleol massratioandsugar-acidratiooffruits in Xinjiangand Gansu were significantly higher than those in Shandong，and the total favonoid mass ratio （79.12mg/g） of fruits in Xinjiang was the highest.The vitamin C mass ratio （9.38mg/g） was lower and the titratable acid mass fraction （0.17%） ）was higher in Shandong. Correlation analysis showed that there was a significantcorrelation between fruitappearance，texturequalityandnutritional quality.‘Xinli No.7'fruit quality comprehensive evaluation of the good performance of the production area for Xinjiang and Gansu production area. 【Conclusion】Diferentproductionareas‘Xinli No.7'qualityhasitsowncharacteristics.Xinjiangand Gansu production areas of thefruit comprehensive quality is beterthan other production areas，more suitable for planting‘Xinli No.7.
