中文摘要	应用RAPD技术,对我国不同产地的锦鸡儿属植物30份材料进行遗传多样性分析,从40个随机引物中筛选出15个有效引物,共扩增出87条DNA片段,其中74条为多态性条带,约占总数的84.1%.30份材料聚类结果可将供试材料分为4个类群:Ⅰ.中间锦鸡儿材料区,Ⅱ.小叶锦鸡儿材料区,Ⅲ.柠条锦鸡儿材料区和Ⅳ.秦晋锦鸡儿材料区,中间锦鸡儿、小叶锦鸡儿和柠条锦鸡儿种间差异不大,有较近的亲缘关系,它们与秦晋锦鸡儿的亲缘关系较远,同时反映出品种间关系与地理起源有一定的相关性.
英文摘要	Peashrub,in common name of Caragana Fabr, there is about 66 species of peashrub were recorded in China, which are mainly distributed in arid and semi-arid areas of North China. All species of peashrub developed typical biological features, which are highly drought-tolerant and good shrubs for dune-fixation,animal feeding,and biological resources for fuel energy and fiber material. They are valuable plants for the ecological restoration of North China. It is very important to analyze the genetic diversity of peashrub for protecting and utilizing them.In this paper,the genetic diversities of 30 peashrubs form different places in North China were analyzed by RAPD markers. Among 87 RAPD bands obtained form 15 primes,74 bands were polymorphic which occupied 84.1% of the total.Cluster analysis showed that the tested materials of 30 peashrubs could be divided into 4 groups: population of C. intermedia ; population of C. microphyl-la ; population of C. korshinskii Kom and population of C. purdomi , the relationships among population of C. intermedi-a , population of C. microphylla and population of C. korshinskii Kom are nearer than population of C. purdomi, it also showed that their relationships are related with the geographic origin.
