中国栽培大豆群体结构不同分类方法的比较
Comparison of various clustering methods for population structure in Chinese cultivated soybean( Glycine max( L. )Merr. )
摘要
Abstract
Using geographic eco-type approach ,STRUCTURE and PowerMarker softwares ,molecular marker information of 135 markers in 215 soybean cultivars randomly selected from China was used to investigate genetic structure of the above population,and its purpose is to find a suitable cluster approach. Results showed that STRUCTURE software results in a maximum pair-wise Fst value of 0. 1083 among subpopulations and a minimum estimate of 85 for the number of loci with highest allelic frequency across subpopulations,suggesting the biggest genetic difference among subpopulations; and a minimum Hs estimate of 0.491, a minimum polymorphism information content value of 0.7376 and a minimum pair-wise Fis value of 0.974 within subpopulation, indicating the largest genetic similarity within subpopulation. This means that STRUCTURE software is available for investigating population genetic structure.关键词
