Abstract:

In order to study the characteristics of wild Actinidia chinensis germplasm resources in Funiu Mountain and screen out excellent germplasm, the wild A. chinensis resources in this area were investigated and collected. Combined with geographical factors, 13 quantitative phenotypic traits such as leaf length, leaf width and petiole length were analyzed and compared by variance analysis, correlation analysis, principal component analysis and cluster analysis. The results showed that the variation of 13 quantitative traits ranged from 10.81% to 47.56%, and the genetic diversity index ranged from 2.90 to 2.94. The size of fruit core and relative core size were significantly different at different longitudes, and the size of fruit core and fruit width were significantly different at different dimensions, and the quantitative traits were closely related to each other. The 19 wild A. chinensis germplasms collected from Funiu Mountain could be divided into 3 groups by cluster analysis. There were 7, 3 and 9 germplasms in groups Ⅰ, Ⅱ and Ⅲ, respectively. The germplasms in group Ⅱ had large leaves, large fruits and moderate proportion. In summary, Funiu Mountain wild A. chinensis had rich phenotypic diversity. According to the phenotypic characteristics of the germplasm, 3 excellent germplasms were screened out, which could be used for breeding and production development.
