为评估中国南方山区野生毛花猕猴桃种质资源的驯化和栽培价值，对在江西省马褂木山自然保护区采集的145个基因型进行了果实品质评估。结果表明，这些基因型的果实在糖、干物质、可滴定酸、可溶性固形物、类胡萝卜素、叶绿素和抗坏血酸含量方面存在显著差异。抗坏血酸含量与可滴定酸呈正相关，总糖、干物质和可溶性固形物含量之间两两呈正相关。聚类分析表明，在遗传距离为1.486时，野生毛花猕猴桃资源可分为6类。
To evaluate the domestication and cultivation value of wild Actinidia eriantha germplasm resources in the mountainous areas of southern China, 145 genotypes collected in the Magu Mountain Nature Reserve, Jiangxi Province, were assessed for fruit quality. The results showed there was significant variation between genotypes in the sugar, dry matter, titratable acidity, soluble solids, carotenoid, chlorophyll and ascorbic acid contents of their fruit. Ascorbic acid content was positively correlated with titratable acidity, and there were pairwise positive correlations among the total sugar, dry matter and soluble solids contents. Cluster analysis showed that the resources of wild A. eriantha could be divided into six groups at a genetic distance of 1.486.
