摘　　要：【目的】评价中国不同地区中猕2号果实品质,建立品质综合评价体系。【方法】以来源于中国12个省份的中猕2号果实为试材,对果实外观品质和内在品质进行测定与分析,利用相关性分析和主成分分析对不同地区中猕2号果实品质进行综合评价。【结果】中国不同地区中猕2号果实品质存在差异,其中外观品质受地区影响较小。通过综合相关性和主成分分析的结果,筛选出横径和硬度作为果实外观品质评价的核心指标,果糖、维生素C和单宁含量作为果实内在品质评价的核心指标。建立了中猕2号果实品质综合评价方程:F综=0.395F1+0.163F2+0.157F3+0.104F4+0.725F5。【结论】中猕2号适应性强,可在不同生态区域推广种植。【Objective】The present experiment was undertaken to assess fruit quality of Zhongmi No.2 from different regions of China and establish the comprehensive evaluation system for fruit quality.【Methods】Zhongmi No.2 fruit samples from 12 provinces were selected as experimental materials.Single fruit weight was measured using an electronic balance.The vertical and horizontal fruit diameters were measured with a vernier caliper,and the fruit shape index was calculated using the formula of fruit vertical diameter/horizontal diameter.The fruit firmness was determined by the digital display penetrometer GY-4-J.Soluble solids content and titratable acids were determined by the digital sugar and acid meter(PAL-BXIACID8 Master Kit,ATAGO).The internal quality indexes,including vitamin C,fructose,glucose and sucrose contents were determined with the national standard GB 5009.86—2016,and the tannin content was determined with the industry standard NY/T 1600—2008.The correlation of fruit quality indexes was analyzed to identify the relationships among different indexes using SPSS software.Principal component analysis of fruit indexes was conducted by SPSS software,and principal component was extracted based on the criterion of feature values greater than one.The 15 fruit index data were standardized as X1,……,X15,which multiplied the feature vectors with the standardized data to obtain the score expressions of the 5 principal components.The comprehensive evaluation equation of fruit quality was established using the principal component variance contribution rate as the weight.【Results】There were differences in the appearance quality indexes of Zhongmi No.2 in different regions of China.The single fruit weight of Sichuan Zhongmi No.2 was the smallest,while Shanghai was the biggest.The average single fruit weight was 110.07 g,with a coefficient of variation of 12.34%.The coefficient of variation for fruit vertical diameter,horizontal diameter and fruit shape index were 4.8%,7.66%and 6.28%,respectively,indicating
