| 摘 要： | 分子育种技术是在DNA水平上直接进行选择，通过对随机分布于整个基因组的分子标记的多态性进行比较，更加全面地了解研究对象的多态性，可以获得更大的信息量，选种的准确性也更高，进而提高奶牛生产效率和经济效益。作者从奶牛分子育种技术的角度入手，阐述了数量性状基因的定位、分子标记辅助选择、转基因育种以及全基因组关联分析这几方面的研究难点、存在问题和研究进展，指出分子育种技术在奶牛育种及改良过程中具有非常重要的作用，进一步研究并应用分子育种技术，不仅可以加速我国奶牛核心群的全面建设，而且对培育种公牛也是非常必要的手段。 |

| Abstract: | Molecular breeding technology is direct selection at the DNA level by randomly distributed molecular markers throughout the genome polymorphism comparison,it is helpful to carry out more comprehensive study of polymorphism on investigated subjects,meanwhile,more information can be got,and the accuracy of selection will be higher,thereby,the milk production efficiency and economic benefits can be improved.From the perspective of the dairy cattle molecular breeding technology,the author expounds the research challenges,problems and research progress on several aspects,such as localization of QTL,MAS,transgenic breeding and GWAS,points out that molecular breeding techniques have a very important role in dairy cattle breeding and improvement process.Further research and application of molecular breeding technology not only can accelerate the development of dairy cows in the core group of comprehensive construction,but also is very necessary to cultivate a bull. |
