育种方法有杂交育种、诱变育种、单倍体育种、多倍体育种、基因工程育种、细胞工程育种等。利用生物变异的原理在生产中如何培养新品种是近几年高考的命题热点之一。命题时常以小麦、水稻、玉米等为素材,综合考查各种育种原理、方法、步骤,并常与遗传、变异、进化、基因工程和细胞工程等知识联系起来进行综合考查。为直观详尽地掌握几种育种方式, Breeding methods are hybrid breeding, mutation breeding, haploid breeding, polyploid breeding, genetic engineering breeding, cell engineering breeding. The principle of using biological mutation in the production of new varieties is one of the hot topics proposition in recent years. Propositions often use wheat, rice, corn and other materials as a material, a comprehensive examination of a variety of breeding principles, methods, steps, and often with genetic, mutation, evolution, genetic engineering and cell engineering knowledge linked to a comprehensive examination. Intuitive and detailed grasp of several breeding methods,
