32份糯玉米自交系的遗传多样性分析
Study on Genetic Diversity of 32 Waxy Corn Inbred Lines
摘要
Abstract
The genetic diversity and relationship of 32 waxy corn inbred lines were studied by SSR markers. Ninety - one pairs of SSR primers giving stable amplified band pattern detected 630 alleles among the lines tested. The average number of alleles per SSR locus was 6.92 with the range from 3 to 16. The value of polymorphism information content (PIC) for each SSR locus varied from 0.34 to 0.91, with the average of 0.72. The genetic distance ranged from 0.57 to 0.92, with the average of 0.78. The result of clustering analysis showed that the 32 inbred lines were divided into Tongxi 5 subgroup, Hengbai 522 subgroup, Zhongyu 04 subgroup, and Hun-he subgroup by UPGMA method. The clustering results were similar to that based on geographical resource and germplasm genealogy.关键词
