摘要: 运用现代分子生物学简单重复区间序列扩增多态性(ISSR)和随机扩增片段多态性DNA(RAPD)两种分子标记技术, 对吉林省主推6个玉米杂交种及其父本、 母本共计18份基因图谱进行鉴别. 以ISSR为主要检测方法、 RAPD为验证方法,分别从30条ISSR引物中选出4条、 从30条RAPD引物中筛选出2条扩增效果明显、 特异性高的引物. 结果表明, 运用ISSR和RAPD-PCR技术提高了玉米品种鉴定和纯度鉴定的准确性.

关键词: 玉米, ISSR, RAPD, 品种鉴别

Abstract: The gene maps of eighteen maize samples were analyzed by intersimple sequence repeat (ISSR) and random amplified polymorphic DNA (RAPD) marker methods. The ISSR method was the primary method and was validated by the RAPD method. 4 highly polymorphic primers were screened out from 30 random ISSR primers and 2 highly polymorphic primers were screened out from 30 random RAPD primers. In conclusion, uniting ISSR combined with RAPD can raise the veracity of indentification.

Key words: maize,  ISSR, RAPD, indentification of varieties
