摘要
用RAPD技术对包括春、冬芥菜型油菜及国外品种在内的36个芥菜型油菜品种的遗传多样性进行了分析。在扩增得到的128条DNA带中,多态性DNA片段达88.28%。分析表明:春、冬油菜间遗传差异较大,国内冬性芥菜型油菜地方种多样性水平较高,25份冬性品种分属Ⅰ、Ⅱ和Ⅲ类群,而春性芥菜型油菜地方种均归于Ⅳ类;印度的RLM198与四川的珙县金黄油菜、澳大利亚品种与我国春油菜品种亲缘关系密切。
The genetic diversty among 36 B. juncea cuhivars was assessed by RAPD technique. Among the amplified 128 DNA bands,polymorphic bands reach 88.28%. High genetic variation existed between spring and winter cultivars. Large genetic diversity among winter cultivars was detected. Twenty-five winter cultivars were divided into three groups (Ⅰ, Ⅱ, Ⅲ), Whereas spring cultivars clustred into separated group (Ⅳ). Close relatedness both between RLM198 from India and Gongxian JinHuang Youcai from Siehuan Province, and beween Australia cultivars and the spring type cultivars of China was found.
