Liaoning cashmere goats,as a key genetic resource of livestock and poultry with Chinese char-acteristics for both cashmere and meat,play an important role in the development of cashmere industry and re-gional economic.However,levels of technology for their genetics and breeding still need to be improved.This ar-ticle discusses the achievements of applying modern techniques of genetics and breeding including whole-genome selection,molecular marker,gene editing,and SNP microarray on the basis of the current situation of farming Liaoning cashmere goat and traditional techniques for breeding.The"Liaoning Cashmere No.1"5K liquid-phase breeding microarray has been used for precise identification of purebred and hybrid individuals in the core population of the original species.The multi-birth gene platform is applicable for the rapid selection and breeding of high-reproductive-rate core populations in breeding flocks.CRISPR-Cas9 gene editing technol-ogy can improve the yield of cashmere,wool quality,and production performance to some extent.SNP microar-rays can achieve high-throughput and efficient identification and analysis of genetic variations in individual goats or populations.Modern techniques of genetics and breeding have demonstrated great potential in the de-velopment of Liaoning cashmere goats.Continuous studies on techniques and policy support are needed to pro-vide support for promoting the efficient and modernized development of Liaoning cashmere goat industry.
