已有百年历史的育种行业是传统农业中最有技术合量的一块。而现代生物育种融合了基因工程、分子生物学等技术手段,产生了转基因作物,实现了对传统农业的巨大改造。生物育种技术的升级,促进了全球农业的产业化程度,生物育种也成为国际农业公司研发和竞争的焦点。基因工程技术突破育种限制杂交育种是最传统的育种方法,它将两个或多个品种的优良性状通过交配集中在一起,再经过选择和培育获得新品种,使优良性状集中在杂交代上。但杂交的过程缓慢繁琐,育种时间长,只能进行本物种或亲缘关系较近的物种杂交,远源物种不能杂交。
The century-old breeding industry is one of the most technologically advanced in traditional agriculture. The modern biological breeding combines genetic engineering, molecular biology and other technical means, resulting in genetically modified crops, to achieve a huge transformation of traditional agriculture. The upgrading of biological breeding technology has promoted the industrialization of agriculture in the world and biological breeding has also become the focus of R & D and competition of international agricultural companies. Genetic Engineering Breaking Breeding Limit Hybrid breeding is the most traditional breeding method. It combines the fine traits of two or more cultivars through mating and then selects and cultivates new varieties so that the fine traits are concentrated on the hybrid generation. However, the process of hybridization is slow and cumbersome, breeding a long time, only the species or genetic relationship of close species hybridization, distant species can not hybridize.
