中文摘要:

      经济社会的发展使人们对牛肉的经济性和肉品质要求提高,培育生长性能和生产性能更加良好的肉牛品种的重要性日益凸显。随着分子生物学技术的进步,动物育种逐渐从表型性状研究向基因调控发展,通过分子标记辅助育种能够更加快速准确的选择目标性状,分子育种技术提高了品种培育效率并降低了成本,且繁育的后代优良性状更加稳定,其应用范围也越来越广泛。目前新疆肉牛分子育种的应用较少,多停留在理论研究阶段,且存在着经费不足和育种场规模小、难以获得足够的样本等问题。本文综合阐述了分子育种的概述、肉牛分子育种研究进展和新疆肉牛分子育种现状,旨在为新疆肉牛分子育种工作提供一定的思路和理论依据。

英文摘要:

      With the development of economy and society, people have higher and higher requirements for beef economy and meat quality, so it is increasingly important to cultivate beef cattle breeds with better growth and production performance. With the progress of molecular biology technology, animal breeding has gradually developed from phenotypic trait research to gene regulation. Through marker-assisted selection, target traits can be selected more quickly and accurately. Molecular breeding technology has been widely used because it improves the breeding efficiency and reduces the cost of varieties, and the good traits of offspring are more stable. At present, the application of molecular breeding of beef cattle in Xinjiang is less, mostly staying in the theoretical research stage, and there are some problems such as insufficient funds and small breeding farms, which are difficult to obtain enough data samples. In this paper, the overview of molecular breeding, the research progress of molecular breeding of beef cattle and the current situation of molecular breeding of beef cattle in Xinjiang were summarized, in order to provide reference materials and theoretical basis for molecular breeding of beef cattle in Xinjiang.
