| 摘 要： | 利用ISSR分子标记技术研究了山东省长岛县南部4岛90份狗尾草材料的遗传多样性及遗传结构.13个ISSR引物共扩增出148个位点,多态性位点比率为70.30%,Shannon信息指数在物种水平上为0.344 9.根据Gst值,遗传变异有16.53%发生在种群间.遗传距离分析表明,NCS种群与DHS种群遗传一致度最高,遗传距离与地理距离之间没有相关性.

| Abstract: | Using ISSR method, the genetic diversity and genetic structure of 90 individuals Setaira viridis（L. ）Beauv in the four islands south of Changdao,Shandong Province were studied in this pa- per. Through the amplification of ISSR with 13 primers,148 loci were detected and the percentage of polymorphic loci was 70.30%. Shannon＇s information index was 0. 344 9 at the species level,genetic variance was 16. 53% among populations according to Gst value. The genetic distances analysis showed that NCS population and DHS population have the highest population genetic identity,genetic distances and geographic distances have no correlation. |
