【摘要】 在人类基因组计划的带动下 ,猪的遗传连锁图谱和细胞遗传学图谱有了较大的进步。利用目前猪基因组图谱的研究成果 ,通过基因组扫描法和候选基因法 ,可以对猪重要经济性状的主效基因位点进行区域定位 ,进而图位克隆 ,找到主效基因 ,为现代遗传育种奠定理论基础。更多还原

【Abstract】 The progress in human genome research and DNA marker technology haveled to a great improvement in the swine genetic linkage map and cytogenetic map. Genome scanning and candidate genes were two methods in localization of important quantitative trait loci(QTL) in swine. After the localization of QTL, major genes affecting economic traits should be acquired by positional cloning and utilized as marker assisted selection in swine breeding.更多还原
