摘　　要：为筛选出优良的大果型毛花猕猴桃种质资源,以10份大果型毛花猕猴桃种质的果实为材料,测定单果质量、果形指数、维生素C、可溶性固形物、可滴定酸等6个主要果实品质性状,进行变异分析、主成分分析和综合评价。结果表明:维生素C含量变异系数最大(22.50%),可溶性固形物含量变异系数最小(11.37%);主成分分析结果,前4个主成分方差累积贡献率为95.09%,其中第1主成分的特征值为2.69,贡献率为44.87%,主要由固酸比、维生素C、可溶性固形物含量和可滴定酸含量决定。根据提取前4个主成分计算果实品质综合评价得分,BC1种质和BC9种质综合得分值大于1,果实品质综合表现较好,特别是BC1种质具有高维生素C特点,可作为种质创新和育种资源利用。In order to screen out excellent germplasm resources of large fruit Actinidia eriantha Benth variety,10 samples of large fruit A.eriantha Benth germplasm were used as materials.Six main fruit quality traits,including single fruit weight,fruit shape index,vitamin C,soluble solids,and titratable acid,were measured for variation analysis,principal component analysis,and comprehensive evaluation.The results showed that the coefficient of variation of vitamin C content was the highest(22.50%),and the coefficient of variation of soluble solid content was the lowest(11.37%).The results of principal component analysis showed that the cumulative contribution rate of the variance of the first four principal components was 95.09%,of which the characteristic value of the first principal component was 2.69,with a contribution rate of 44.87%,mainly determined by the solid-acid ratio,vitamin C,soluble solid content,and titratable acid content.Based on the extraction of the first four principal components,the comprehensive evaluation score of fruit quality was calculated.The comprehensive scores of BC1 and BC9 germplasm were greater than 1,indicating good overall performance in fruit quality.Especially,BC1 germplasm has high vitamin C content,which can be used for germplasm innovation and breeding resource.
