摘　　要：牦牛作为栖息于世界海拔最高地区的哺乳动物,以其独特的耐寒耐旱、适应性强和高繁殖力等优势,在青藏高原等海拔3 000 m以上地区发挥着不可替代的经济和生态作用。该研究通过分子遗传学技术手段,如基因型测序、基因组选择及基因编辑等,对牦牛遗传资源进行全面的评估和优良性状的精准鉴定。通过分析分子遗传学对牦牛的研究现状及品种选育意义,提出相对应的选育策略,旨在选育出更适应高寒环境、具有更高营养价值和更好经济性状的牦牛品种,进一步增强牦牛作为“高原之舟”的生态和经济价值。Yaks,as mammals living in the world's highest altitude areas,play an irreplaceable economic and ecological role in areas above 3000 m,such as the Qinghai Tibet Plateau,due to their unique advantages of cold and drought resistance,strong adaptability,and high reproductive capacity.This study comprehensively evaluates the genetic resources of yaks and accurately identifies excellent traits through molecular genetic techniques such as genotype sequencing,genome selection,and gene editing.By analyzing the current research status and breeding significance of molecular genetics on yaks,corresponding breeding strategies are proposed with the aim of breeding yak varieties that are more adaptable to high-altitude environments,have higher nutritional value,and better economic traits,further enhancing the ecological and economic value of yaks as“high-altitude boats”.
