摘　　要：【目的】采用相关性分析、主成分分析方法对中国农业科学院特产研究所软枣猕猴桃资源圃保存的88份软枣猕猴桃资源品质性状进行综合评价,建立果实评价体系,为筛选优质软枣猕猴桃资源提供理论依据。【方法】以88份软枣猕猴桃为试材,对果实横径、纵径及可溶性固形物、总酚、总糖、维生素C含量等15项果实品质相关指标进行测定,采用相关性分析与主成分分析进行综合评价。【结果】不同软枣猕猴桃种质资源果实的15项品质指标间存在差异,且各指标间存在相关性。111002的横径、L060503的纵径和单果质量、S090602的侧径、L080308的可溶性固形物含量、W030101的可滴定酸含量、140301的总糖含量、W110101的总酚和维生素C含量、060203的有机酸含量显著高于其他软枣猕猴桃。通过主成分分析对88份软枣猕猴桃种质资源果实的15项果实品质指标进行简化提取,共提取到5个主成分,累计方差贡献率达75.384%。【结论】通过相关性分析、主成分分析筛选出果实横径、纵径、单果质量及可溶性固形物、可滴定酸、总糖、总酚、有机酸、维生素C含量作为软枣猕猴桃果实品质评价的核心指标,其中L060503、060203、190403、L110203、040103为排名前5的软枣猕猴桃优质资源。【Objective】Correlation analysis and principal component analysis were used to comprehensively evaluate the quality traits of 88 accessions of Actinidia arguta resources preserved in the A.arguta resource nursery of the Institute of Specialty Products,Chinese Academy of Agricultural Sciences,in order to establish a fruit evaluation system and provide theoretical basis for the screening of high-quality A.arguta resources.【Methods】Using 88 accessions of A.arguta fruit resources as test material,the transverse,longitudinal and lateral diameters of the fruits were measured with vernier calipers,the mass of the fruits was measured with a balance,the soluble solid content was measured with a portable digital brix meter,the titratable acid content was measured with a titration method using sodium hydroxide solution,the total sugar content was measured with a sulfuric acid-anthracenone colorimetric method,and the total phenol content was measured with a Folin-phenol method.The titric acid,quinic acid,malic acid,lactic acid and vitamin C content were measured using High Performance Liquid Chromatography.Correlation analysis and principal component analysis were used for comprehensive evaluation.【Results】Differences were found among the 15 quality indexes of the fruits of the different A.arguta germplasm resources,and there were correlations among the indexes.The maximum fruit transverse diameter(33.07 mm)was found in 111002,the maximum fruit longitudinal diameter(44.49 mm)in L060503,and the maximum fruit lateral diameter(30.07 mm)in S090602.The fruit mass ranged from 4.13 to 18.31 g.The maximum fruit mass was found in L060503.The soluble solids content varied in the range of 7.13%to 17.73%,and the highest content was found inL080308,followed by 0600203.The titratable acid content ranged from 2.76 to 15.69 g·L^(-1),and the highest content was found in W030101.The solid-acid ratio of W010401 fruits reached a maximum of 4.93.The total sugar content varied from 14.27 to 88.02 g·L^(-1),the highest content was foun
