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.

Key words: dairy cattle; molecular breeding technology; research progress
