摘　　要：分子标记、QTL的研究和辅助选择应用已经得到很大的发展,一批与大豆形态性状、产量性状、品质性状、生态性状、抗生物胁迫性状相关的QTL在国内外均有报道。但近年来分子标记和QTL研究在比较发达的国家已经转向功能标记(FM s:EST-SSR、SNP和候选基因)的研究,相继启动大豆EST计划和大豆功能基因组计划,以期使功能基因和性状直接联系起来,目前已经取得了显著成效。而我国目前分子标记和QTL的研究还主要集中在利用随机标记(RM s:RAPD、SSR和AFLP)对性状进行研究。该文就国内外大豆分子标记和分子标记辅助育种及分子育种技术发展动态和发展中存在的主要问题做一概述。In recent years,molecular markers, QTL-assisted selection research and application has been greatly developed, and a number of important traits related QTL have been studied ,such as morphological traits,yield traits,quality traits,ecological traits, and abiotic stress resistance. However, developed countries have shifted to the functional markers studies, such as EST-SSR, SNP and candidate gene marker. Soybean EST project and soybean functional genomics program directly have started and aim to have a view on functional genes linked to traits. At present, molecular markers have focused on the use of random markers for QTL analysis of traits,such as RAPD,SSR and AFLP in domestic land. This study will show main problems and development of soybean molecular markers and marker-assisted selection breeding in the development process.
