| 现代分子生物学技术和新的统计方法,大大促进了植物数量性状基因(QTL)的解析遥连锁作图和关联作图是目前植物数量性状基因解析的重要方法M两者在QTL 定位的精度和广度。提供的信息量、统计分析方法等方面具有明显的互补性。连锁作图可以初步对目标性状基因进行定位，而关联作图则可快速对目标基因进行验证和精细定位，并针对特定候选基因提供大量信息袁验证候选基因的功能遥综述了近10年来棉花数量性状的连锁作图和关联作图最新进展，并结合两种方法对棉花的QTL研究前景进行了展望。 |
| 英文摘要: |
| Both modern molecular biology technique and new statistical methods greatly promoted the analysis of plant quantitative trait loci (QTL). Linkage mapping (LM)and association mapping (AM) are two important methods for QTL analysis. Both them have obvious complementarity in the accuracy and breadth of QTL mapping, the provided information, and the statistical analysis method. Linkagemapping can preliminary locate the target trait gene, while association mapping can quickly achieve the verification and fine mapping of target gene; moreover, it can also verify the candidate gene function according to a lot of information provided for a specific candidate gene. In this paper, the new advances were reviewed from the linkage mapping and association mapping of cotton quantitative traits. The research prospects of cotton QTL were analyzed by combining the two methods.· |
