| 摘 要： | 为了研究P1811自交系的亲缘关系,利用SSR标记技术分析了77个玉米P1811近缘系的亲缘关系及遗传多样性.结果表明:25对多态性较好的随机引物中共检测到222个等位基因变异,每对引物检测等位基因4～16个,平均8.88个;SSR引物的PIC值介于0.615 7～0.938 1,平均为0.87;GS变幅为0.518 ...

| Abstract: | The genetic diversity of 77 maize P1811 relatives were studied by simple sequence repeats(SSR) markers to know the genetic relationship of self-bred line P1811.The results showed that 222 alleles were detected from the 25 SSR primers giving stable amplified band patterns.The average number of alleles per SSR locus were 8.88 with a range of 4~16.The value of polymorphism information content(PIC) for each SSR locus varied from 0.615 7 to 0.938 1with an average of 0.87.The 77 maize P1811 relatives were divided... |
