摘要: 为研究罗田迟熟板栗品种种质资源遗传信息,采用ISSR分子标记技术,对‘桂花香’、‘九月寒’等8个板栗品种分类鉴定及亲缘关系进行分析。(1)ISSR-PCR反应体系及引物筛选。选择了条带的数量多和清晰度高的反应体系,应用‘九月寒3号’筛选前期设计的21条ISSR引物,淘汰扩增效果差、带型不易辨认的引物,最终选定7条引物用于迟熟板栗品系的分析;选取的7条ISSR引物总共扩增出140条清晰、重复性较好条带,其中,多态性条带有106条,多态性条带比率达75.7%。(2)应用NTSYS 2.10e软件进行UPGMA法聚类分析,在相似系数0.45处将8个板栗品种大致分为2类。结果显示,‘羊毛栗’、‘桂花香2号’与其他板栗品种在遗传上有较大差异。

Abstract: In order to study the germplasm genetic information of the late ripe varieties of Chinese chestnut in Luotian Hubei, in this paper, the classification and genetic relationship of 8 series of Chrysanthemum cultivars were investigated using cluster analysis of ISSR molecular markers. For the reaction system of ISSR-PCR and primer selecting, we selected the number of bands and early high-definition reaction system to screen 21 primers, eliminate primers of poor amplification and difficultly identified bands, and ultimately determine the 7 primers used for late ripe varieties of chestnut identification. For ISSR cluster analysis, the selected ISSR primers amplified 140 clear and reproducible ISSR bands, and 106 bands of them were polymorphic with a polymorphism rates up to 75.7%. With NTSYS 2.10e software, 8 Chinese chestnut cultivars can be divided into two categories by UPGMA cluster analysis at the dice similarity coefficient of 0.45. The analysis result showed that ‘Yangmaoli’ and ‘Guihuaxiang No.2’ had genetic differences with other late ripe varieties.
