摘    要:分子标记连锁图的构建为植物基因组的结构和功能分析提供了有力的工具。较高密度的遗传图谱在数量性状基因定位、图位克隆重要农艺性状基因等研究中发挥了巨大作用。应用栽培大豆长农4和半野生大豆新民6杂交得到的F8代重组自交系,构建了一张较高密度的遗传图谱。该图谱共有240个标记,其中包括2个形态标记、100个RFLP标记、33个SSR标记、42个AFLP标记、62个RAPD标记和1个SCAR标记,分布在22

关 键 词:大豆 遗传图谱 分子标记 基因组 QTL定位

Abstract:Molecular linkage maps provide a powerful tool for the analysis of plant genome structure and function including the detection of quantitative trait loci (QTL). The molecular linkage map of soybean was constructed using an 88-individual RIL population derived from a cross between cultivated Changnong 4 and semi-wild Xinmin 6. The map contains 22 linkage groups and 240 markers, including 100 RFLP, 33 SSR, 62 RAPD, 42 AFLP, 1 SCAR and 2 morphological markers. It covers approximately 3 713.5 cM of soybean genome. Analysis of 72 RFLP markers showed that 16 of them revealed two or more independent loci and it suggested that there is an extensive homologous region in soybean genome. This map compared very well with the other published soybean maps.
Keywords:soybean  genetic map  molecular marker  genome
