亚洲栽培稻程氏指数与SSR标记分类的比较分析
Comparison of Cheng's Index- and SSR Markers-based Classification of Asian Cultivated Rice
摘要
Abstract
A total of one hundred cultivated rice accessions were grouped based on Cheng's index and SSR polymorphism. The results showed that the subpopulation features of allozyme group I (indica) and allozyme group VI -A (temperate japonica) were obvious both classified by Cheng's index and SSR marker, with goodness of fit ranging from 73. 3% to 100%. Mantel test revealed that the Euclidean distance of Cheng's index was significantly correlated with Nei's genetic distance of 109 SSR loci (r=0. 466, P<0. 01). According to both model-based structure and UPGMA cluster analysis, the classification results at subspecies level based on Cheng's index coincided with that on SSR marker. Within subspecies, the subpopulations classified by Cheng's phenotypic characters showed lower goodness of fit than SSR marker. In addition, allozyme group II (aus, boro) and allozyme group VI (temperate japonica, tropical japonica) had more mixture types based on SSR locus analysis.关键词
