摘　　要：为了选育耐贮藏且风味品质优异的猕猴桃(Actinidia)新品种,对美味猕猴桃(A.deliciosa)的3个野生品种‘kvf54’、‘kvf6’、‘鑫美’和3个栽培种‘秦美’、‘华美’、‘徐香’的品质和贮藏特性等进行比较分析。结果表明,常温和1℃贮藏下‘kvf54’和‘徐香’的硬度下降趋势相近,优于其他品种,且‘kvf54’的维生素C(VC)含量最高。而在相同贮藏条件下,‘鑫美’可溶性固形物含量积累速度最快,淀粉和可滴定酸含量最少,贮藏性能不佳。‘kvf54’相比于其他品种的贮藏性更好,VC、糖类物质等含量高,是可用于培育耐贮藏新品种的优质材料。To select new Actinidia varieties with good storage and flavor quality,the quality and storability of three wild varieties‘kvf54’,‘kvf6’and‘Xinmei’of A.deliciosa and three cultivated varieties‘Qinmei’,‘Huamei’and‘Xuxiang’were compared and analyzed.The results showed that under room temperature and 1℃storage,the hardness of‘kvf54’and‘Xuxiang’decreased in a similar trend,which was better than other varieties,and‘kvf54’had the highest content of vitamin C(VC).However,under the same storage conditions,the soluble solids content of‘Xinmei’accumulated the fastest,the starch and titratable acid contents were the least,showing poor storage performance.Therefore,compared with other varieties,‘kvf54’had better storability,higher contents of VC and sugar,so it was a high-quality variety that could be used to breed new storage-tolerant varieties.
