欧洲玉米种质BC8241Ht衍生系的SRAP多态性与亲缘关系分析 总被引:2,自引:0,他引:2
Analyzed and identified SRAP polymorphism and genetic relationship on derived lines from Europe maize germplasm BC8241Ht at DNA molecular level,27 SRAP primer combinations were used to amplify the genome DNA of 21 maize lines of including derived lines from BC8241Ht.Total of 275 SRAP bans were observed and 131 out of these(47.6%) were polymorphic,and the polymorphism indicated that 21 maize lines used in the present study had abundant genetic diversity.The cluster analysis based on SRAP markers showed that 10 BC8241Ht derived lines were clustered in one group,but they were further clustered in first or third sub-groups.The close genetic relationship existed in 10 derived lines from Europe maize germplasm BC8241Ht,but the genetic differences also existed each other in the derived lines.In the course of improving the germplasm and its derived lines,they should be avoided mixing with Lvdahonggu,Tangsipingtou,PN and Southwestern local germplasm,and it can be improved by introducing tropical,subtropical germplasm. 相似文献
