摘　　要：育种是通过发现自然变异、人为创造变异,进而获得稳定遗传材料的过程。目前,国内麦类作物育种仍然以常规育种方法为主,对分子标记辅助选择、转基因和基因编辑等分子育种技术的利用还较少。在植物育种方面,分子技术育种具有育成品种时间短、育种目标更明确的巨大的优势,是未来育种工作的大势所趋。因此,熟练的应用分子技术对推动育种工作的高效发展具有重要意义。Breeding is the process of discovering natural variation,artificially created variation,and then obtaining stable genetic material.At present,the breeding of wheat crops in China is still dominated by conventional breeding methods,and the use of molecular breeding technologies such as molecular marker-assisted selection,transgenesis and gene editing is still relatively small.In terms of plant breeding,molecular technology breeding has the great advantages of short breeding time and clearer breeding goals,which is the general trend of future breeding work.So,the skilled application of molecular technology is of great significance to promote the efficient development of breeding work.
