摘　　要：野豌豆属(Vicia)牧草为自花授粉二倍体植物,具有很好的防风固沙及保水作用,适宜在高寒和高海拔地区种植,是我国高原牧区重要的蛋白饲料来源。本研究从中国、美国、德国、埃塞俄比亚等22个国家,收集了43份野豌豆属牧草种质,对其根尖细胞的有丝分裂中期染色体进行核型分析。结果表明,染色体数目有5种:10、12、14、16、24。核型分类有6种:2A、1B、2B、3B、2C、3C。本研究统计了野豌豆属43份种质的核型数据,为揭示野豌豆属细胞学特性和演化趋势奠定了基础。Most species in Vicia genus are important legume crop that are commonly used as windbreak and sand water conservation. It is suitable for cultivation in alpine and high-altitude areas,which supply protein feed for Tibet plateau in China. Here,we collected 43 Vicia germplasms from 22 countries such as China,America,Germany and Ethiopia. The chromosomal karyotypes of 43 accessions were analyzed by the root tip cells. The results showed that there were five types of chromosome number: 10,12,14,16 and 24. There are six types of karyotypes: 2A,1B,2B,3B,2C and 3C. In the present study,the chromasome karyotypes of 43 Vicia accessions were comprehensively calculated which provided the important scientific basis for the researches of cytological characteristics and evolutionary.
