36个贵州主要玉米自交系的SSR遗传分析
Study on Genetic Diversity of 36 Main Maize Inbred Lines in Guizhou
【摘要】 利用SSR标记分析了36个玉米自交系的遗传多样性,结果表明,多态性、重复性均较好的引物有34对,用此34对SSR引物检测到69个等位基因;SSR位点检测出的平均等位基因3.4个;SSR分子标记将其划分为5组,与系谱分析基本一致。认为,SSR标记系统适合于玉米种质的遗传多样性研究。
【Abstract】 The results from analyzing genetic diversity of 36 maize inbred lines by SSR marker showed that 34 pairs of primers with good polymorphism and replication were selected,69 alleles were detected by 34 pairs of SSR primers and average 3.4 alleles were detected on each SSR locus.36 maize inbred lines could be clustered into five groups,which accords with parentage determination basically.Therefore,SSR marker system can be used in genetic diversity analysis of maize germplasm resources.
