摘  要:
利用SSR标记技术研究了6份标准测验种和43份黑龙江省常用玉米自交系的遗传多样性。63对扩增带型稳定的SSR引物在供试材料中检测出237个等位基因变异,每对SSR引物检测等位基因2 ̄10个,平均3.76个,平均多态性信息量(PIC)和有效等位基因数(NE)分别为0.52和2.35。用UPGMA方法将49份自交系划分为四平头、Lancaster、旅大红骨、自330、PA、PB、Reid、其他等8个类群。划群结果与其系谱分析基本相符。可将黑龙江省玉米种质归纳为Reid和非Reid两大类,其中Reid种质具有较大的利用潜力。

摘  要:
Genetic diversity of 6 standard tester and 43 maize inbred lines in Heilongjiang Province were analyzed by SSR(Simple sequence repeats) technique.Sixty-three pairs of SSR primers giving stable and polymorphic amplification profiles detected 237 alleles among 49 inbred lines.The average number of alleles per SSR locus was 3.76 with a rang from 2 to 10.The value of polymorphis information content(PIC) and effective number of alleles(NE) for each SSR locus educed an average of 0.52 and 2.35.The UPGMA analysis classified 49 inbred lines into 8 groups(Sipingtou,Lancaster,Luda Red Cob,zi330,PA,PB,Reid and the others).Which corresponded to the heterotic groups determined by their pedigree information.The 49 inbred lines can also be classified into2 clusters(Reid and no-Reid),and the Reid germplasm have more potential value.
