没有育种材料、方法和理论上的突破,便不会有育成品种方面的飞跃。在探索高产育种的新途径中,近年来国内外很重视高光效育种这一课题的研究,我国已相继召开了两次全国作物高光效育种会议。C_4作物的光效高于C_3作物,如能将C_4作物的光效导入C_3作物,可能是高光效育种中一个颇值得探索的方面。 Without breeding materials, methods and theoretical breakthroughs, there will be no leap in breeding varieties. In exploring new ways of high-yielding breeding, in recent years, great attention has been paid to the research of high-efficiency breeding at home and abroad. China has successively convened two national high-efficiency crop breeding conferences. C_4 crops have higher light efficiency than C_3 crops. If C_4 crops can be introduced into C_3 crops, C_4 crops may be worth exploring in high light efficiency breeding.
