| 摘 要： | 【目的】探讨不同国家（或地区和组织）间粳稻选育品种的遗传相似性和遗传差异，旨在为世界各地的粳稻品种能够有效利用于水稻育种提供科学依据。【方法】利用34对SSR引物对不同地理来源包括20个国家（或地区和组织）的313份粳稻选育品种进行遗传相似性和聚类分析。【结果】共检测到198个等位基因，平均每对SSR引物检测到的等位基因数为5.8235个。RM320、RM531、RM1、RM21和RM336的等位基因数较多，分别为16、13、12、10和10个；RM320、RM336、RM286、RM531和RM21的遗传多样性指数较高，分别为2.3668、2.0041、1.9684、1.9508和1.7203。各国家（或地区和组织）粳稻选育品种的遗传相似系数变异范围为0.279～0.918，平均值为0.653。纬度和地理位置相近的国家间粳稻品种的遗传相似系数较大，基本聚为同一个类群，而纬度差异较大，地理位置较远的国家间粳稻品种的遗传相似系数较小，聚为不同类群。 【结论】粳稻品种的遗传相似性与纬度和地理位置有着密切的联系。

| Abstract: | The genetic similarity of 313 japonica developing varieties from 17 countries and 2 international organizations was analyzed using SSR markers. With 34 SSR primers which were polymorphic and uniformly distributed in rice genome, total 198 alleles were detected among these developing varieties with the average number of alleles per pair of primers was 5.8235. RM320, RM531, RM1, RM21 and RM336 possessed more alleles, which were 16, 13, 12, 10 and 10 respectively. RM320, RM336, RM286, RM531 and RM21 showed higher genetic diversity indexes, which were 2.3668, 2.0041, 1.9684, 1.9508 and 1.7203 respectively. The latitudes of Korea, Democratic People’s Republic of Korea, Japan, Russia, China, America, Hungary, Bulgaria, France, Italy and Turkey (group I) were higher than 30ºN, in which the genetic similarity coefficients of japonica developing varieties ranged from 0.697 to 0.918 with the average of 0.797. The latitudes of Nepal, Egypt, Mexico and Senegal (group II) were between 15ºN and 30ºN, in which the genetic similarity coefficients of japonica developing varieties ranged from 0.381 to 0.618 with the average of 0.503. The latitudes of Brazil, West Africa Rice Center(WARDA), International Center for Tropical Agriculture(CIAT) and Chile (group III) were lower than 15ºN, in which the genetic similarity coefficients of japonica developing varieties ranged from 0.649 to 0.757 with the average of 0.701. The genetic similarity coefficients of japonica developing varieties among different countries or organizations of different groups were smaller than them among different countries or organizations of the same group on the whole. The rice varieties from higher latitude countries were clustered together, while the rice varieties from lower latitude countries or organizations were clustered together. The results indicated the genetic similarities among japonica developing varieties had a close relationship with the geographical position, especially with the latitude of these japonica developing varieties. |
