摘要: 利用SSR,AFLP两种分子标记方法研究了23个玉米种质材料的遗传多样性,并对这两种分子标记系统进行了比较。利用筛选出的40对SSR引物,检测到了202个等位基因。用12对AFLP引物组,检测到了444条有多态性的带。SSR和AFLP分子标记均有很高的多态性,SSR位点的平均多态性信息量(PIC)值达0.60,而AFLP多态性带比例是72%。两种分子标记结果将玉米种质划分为5组,与系谱分析基本一致,两种分子标记划分的结果也相近。研究认为SSR,AFLP两种分子标记系统均适合于玉米种质的遗传多样性研究。

Abstract: The genetic diversi ty of 23 maize inbred lines and one te osinte accession was analyzed based on microsatelli te (SSR) and AFLPs markers. With 40 pai rs of SSR primers, total ly 202 polymorphic f ragments were detected. Twelve AFLP primer combina tion (Pst/Mse ) were used, and total ly 444 polymorphic bands were produced. BothSSRs and AFLPs were highly polymorphic. The average of polymorphic informat ion content (PIC) was 0. 6 for SSRs. Percentage of polymorphic AFLP bands was 72%.The resul ts of cluster analysis showed that the acces sions asses sed could be clustered into five groups in both marker sys tems. This is partly in accordance wih the previous classi fication based on conventional methods but wi th some dif ference. It was suggested that both sys tem can be used to analyze the genet ic diver sity of maize inbred lines.
