Abstract

Abstract:

In order to select a better strategy for core collection construction. In this study, we based on the data of 20 phenotypic traits of 480 tomato germplasms, 8 clustering methods and 5 different sampling proportions were compared; On this basis, two genetic distances, the sampling proportion of the top two, three sampling methods and the clustering method of the top two were used for combination test, and the representative evaluation of the 24 core collections were carried out. The results showed that the order of systematic clustering methods were Ward’s method>Weighted pair-group average>Complete linkage>Weighted pair-group average>Centroid method>Single linkage>Unweighted pair-group average. The order of sampling proportions were 15%>30%>25%>20%>10%. The best construction method of combination test was that the genetic distance was Euclidean distance, the sampling proportion was 15%, the sampling method was random sampling method, and the clustering method was the Single linkage. This study provided the optimal construction strategy for the construction of core collection, and provided theoretical basis and technical support for the related research of tomato germplasm resources in Ningxia.

Key words: Ningxia, tomato, germplasm resources, core collections, construction strategy
