Variation in fruit quality within wild Actinidia eriantha germplasm

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.
