| 摘 要： | 利用RAPD方法和统计学分析方法对代表我国长江中、下游地区的浙江省和湖北省89份白菜型油菜地方品种进行了遗传多样性及其相关性研究.从农艺性状的聚类分析将两省品种划分为独立的两大类群.RAPD指纹图谱以DNA分子水平的聚类分析可以将89份白菜型油菜品种分为2类群和2个簇及3个亚簇,进一步反映品种间亲缘关系,表明地方品种间具有非常丰富的遗传多样性.

| Abstract: | The genetic diversity among 89 accessions of Brassica campestris from Hubei and Zhejiang provinces in China was analyzed by random amplified polymorphic DNA Markers (RAPDs). Twenty primers selected from two hundreds primers amplified 184 fragments and 139 bands of them showed polymorphisms. Polymorphic rate was 75%. Dendrogram was constructed by SPSS software. Dendrogram of agronomic traits showed that the oilseed in two provinces were differentiated. Dendrogram of RAPD showed that the cultivars in two provinces had relativity. The analytic results indicated that there were abundant polymorphisms in the tested oilseed rape cultivars in two provinces. |
