摘要: 利用随机扩增多态性DNA (RAPD) 在一个葡萄的种间杂交组合〔毛葡萄8324296 (Vitis quinquangularis) ×欧洲葡萄粉红玫瑰(V. vinifera) 〕的F1 群体中发展分子标记,共产生了89 个稳定的RAPD 标记,连同4 个形态标记(花型、霜霉病抗性、果皮颜色、果汁颜色) 构建了一个葡萄RAPD分子连锁图。该图覆盖基因组总长度为1 033 cM,标记间平均距离为17.8 cM, 为毛葡萄连锁图谱的构建提供了一个连锁框架。

Abstract: A set of 280 randomoligonucleotide perimers was screened for random amplified polymorphic DNAs (RAPD) fragments within a sample of 60 F1 hybrids to generate RAPD markers and construct the molecular linkage map fromtwo parents 8324296 (V. quinquangularis) and Muscat Rose (V. vinifera) . 89 repeatable RAPD markers as well as four morphological markers (flower type , grape downy mildew2resistance , berry color and juice color) were obtained. The map consisted of 11 linkage groups , it covered a total genetic distance of over 1 033 cM (centimorgan) , the average distance between markers was 17.8 cM. It supplied a linkage framework for a more saturated linkage map of grape.

Key words: RAPD, Molecular marker, Linkage map, Grape
