摘　　要：绵羊的繁殖特性已成为绵羊生产的一个重要研究方向,对绵羊繁殖力进行遗传改良是提升中国绵羊生产水平的必由之路,母羊的年产羔能力主要受单胎产羔数和季节性发情的影响。本研究对影响产羔能力的排卵数和季节性发情相关基因及miRNA的研究进行了简要的综述,并对全基因组比较在繁殖性状相关QTL检测中的应用进行了展望。Reproductive traits of sheep has became an important research area in sheep industry. Genetic improvement of sheep fecundity is the only way to improve sheep production levels in China. The annual ewe lambing ability is mainly affected by the impact of seasonal estrus and the litter size of single births. In this view, the author gives a brief review on ovulation and seasonal estrus related genes and miRNAs, and prospects the genome wide comparison used in the detection of QTI. about re productive trails.
