38份梨品种基于ISSR的多样性的低温特性研究
Low-chilling character research on the diversity of ISSR among 38 pears
基于ISSR标记技术对38份梨品种的遗传关系进行聚类分析，以得出梨的低温特性与聚类结果之间的相互关系。实验从96条ISSR引物中筛选出19条特异性好的引物，共扩增出111条带，其中特异性条带86条，占77.5%。遗传相似性系数在0.69~0.97之间，将供试品种分为西洋梨和东方梨两个大品系。东方梨又分为豆梨，砂梨和以棕包梨为首的三个聚类，在大部分砂梨的聚类分析中，其多样性与低温需冷量基本相关。从而为南亚热带地区梨花芽休眠解除的低温特性研究提供一定参考。
In order to find out the relationship between low-chilling character and clustering result,clustering analysis of 38 species of pear based on ISSR was done.19 specific primers were picked out among 96 ISSR primers,111 products amplified and 77.5%(86) of them are specific.The genetic similarity was between 0.69 and 0.97,the testing species were divided into western pear and oriental pear.Oriental pear include dou pear,sand pear,zhongbao pear and so on. Diversity of sand pear and its low-chilling character is related to each other according to clustering analysis. So as to provied reference to low-chilling hour research of flower bud releasing of south subtropical pear speices.
