甘蓝型油菜MAGIC群体结构分析
Population structure of Brassica napus MAGIC population
摘要
Abstract
To explore the structure of Brassica napus MAGIC (multi-parent advanced generation intercross) population,genetic diversity and genetic distance of the B.napus MAGIC (composed of 554 lines) were initially illustrated by 60 pairs of SSR (simple sequence repeat) primers.Among these 60 pairs,a total of 261 alleles were detected,with 4.35 alleles per pair,and the average PIC (polymorphism information content) value of 0.48.Population structure analysis using STRUCTURE 2.3.4 showed that this B.napus MAGIC population was divided into 2 subpopulations,with 303 lines in subpopulation 1 and 234 lines in subpopulation 2,and the remaining 17 lines had no specific subpopulation attribution,belonging to mixed subgroups.The results suggested that the MAGIC population had high genetic diversity.关键词
