基于表型多样性构建山西大豆地方品种核心种质
Establishment of soybean core collection based on phenotypic characters in Shanxi Province
摘要
Abstract
In order to solve the problems of large number of soybean germplasm resources,heavy renewal bur-den and low breeding efficiency for fine varieties in Shanxi,the genetic diversity of 20 phenotypic traits for 1999 soybean germplasm resources was used to establish a core germplasm collection.Unweighted pair-group method with arithmetic means was used to construct core germplasm by randomly sampling the resources in each region af-ter systematic clustering.The core germplasm retained 10.66%of the total number of original germplasm.The repre-sentativeness of the established core collection was comprehensively tested by both multiple characteristic values(minimum,maximum,mean,standard deviation,coefficient of variation,and diversity index)and evaluation parame-ters(percentage of mean difference,percentage of variance difference,range coincidence rate,variable rate of coeffi-cient of variation,and phenotypic retention ratio).The results indicated that the t-test results of diversity index of 19 phenotypic traits between core germplasm and original germplasm were not significant,and the percentage of mean difference,range coincidence rate,variation rate of coefficient of variation and variance difference were 0,136.29%,106.44%and 15.79%,respectively.The first 7 principal components of core germplasm and original germplasm were the same,and the cumulative contribution rate was 85.761%and 85.857%,respectively.The re-sults demonstrated that a total of 213 core germplasm resources effectively represented the genetic diversity of Shanxi soybean local varieties.关键词
