| 摘 要： | 利用RAPD分子标记技术，对来自欧洲、美国和我国北方的共48份榛子品种或品系（包括4个种及种间杂种）的遗传多样性进行了分析．从150条随机引物中筛选出24条引物，共扩增出142条清晰可重复的带，其中多态性带130条，比例为91．5％．聚类分析将48份榛子种质分为5组：欧榛、平榛各自列为1组；杂交榛分成2个组；另外一组包括滇榛和藏榛2份种质．研究结果对榛子的种间亲缘关系进行了验证，且为同种不同品种的亲缘关系提供了更为详细的信息． |

| Abstract: | Random amplified polymorphic DNA(RAPD) analysis was carried out to measure the genetic diversity of 48 accessions of Corylus(include 4 species),which were collected from Europe,America and Northern China.Twenty-six polymorphic primers were screened out of 150 random primers and 142 bands were distinguishable and reproducible.Among them,130 bands(91.5%) were polymorphic.The 48 accessions were divided into 5 groups according to the cluster analysis.Corylus avelana and C.heterophylla belonged to the individual group.The hybrid Corylus were divided into 2 different groups.The other group contained C.yunnanensis and C.ferox var.thibetica.Our results were consistent with the traditional taxonomy and provided more valuable information for Corylus accessions belonging to the same species. |
