摘要

The collection of wild kiwifruit germplasms has already proved its worth with the development of valuable new kiwifruit cultivars.Through field investigation and consulting the existing literature,this paper illustrates that Jiugongshan region in China is a unique gene bank of excellent wild kiwifruit germplasm resources on the boundary between Hubei and Jiangxi provinces.It is also one of the important birthplaces of breeding materials for new kiwifruit cultivars in China.The paper introduces the main characteristics of two wild red-fleshed kiwifruit germplasms discovered in this region,and one of them is a new large-fruited variant of wild red-fleshed kiwifruit.The main fruit qualities of the large-fruited form are that short fruit stalk,large fruit(the maximum fresh fruit mass of about 81.2 g),moderate sweetness and sourness,reddish to red inner pericarp,the ripe fruit soluble solids content 14.10%,total sugar 8.84%,total acid 1.18%,vitamin C 644.3 mg/kg.It is expected to be cultivated into a new edible cultivar(line)or ornamental and edible cultivar(line)of Actinidia chinensis,which has a broad prospect of development and utilization.
