“超级玉米”的内涵与耐密品种选育

超级玉米是在现有玉米杂交优势利用的基础上,针对创新研究内容、突破杂优增产潜力、实现品种的零风险、低耗、资源高效利用化,以便充分发挥玉米的生产潜力,最终达到玉米生产最大增值效益的跨越。针对我国现有种质利用状况、品种的增产潜力、专用化以及不同地域生态区特征、复杂的栽培制度等,"超级玉米"的内涵要有一定的广延性,赋予其更广泛的内容。"超级玉米"不仅提出了一个更新、更高、更远的追求目标,而且会促使我国玉米育种遗传基础理论得以不断创新。"超级玉米"实现高产、超高产,必须依赖群体密植化。因此,耐密玉米品种的选育是超级玉米遗传育种理论不断创新的重要技术内容。

Intension of Supercorn and Compact Corn Breeding

Super-corn is aimed at research innovation,break through yield potentiality,breeding of zero-risk,low consumption,and resources high-effect use come true,in order to fully played potential potentiality,ultimately realize a overleap of maximal added benefit.Facing up to existent available utilizatial level of germplasm,the potential of maize's increasing production,specialization,characteristics in different regions,complicated planting system and so on,the intension of super-corn,to obtain extensibilities,needs more and extensive content.There's no doubt that super-corn will not only set up a renewal,higher and more distant objective for scientific workers,but also promote the continual innovation of maize's new genetics basic theory in China.Though,the intension of super-corn has got more and extensive content,we can't achieve higher yield,without the help of compact corn breeding.That's to say,compact corn breeding will be the core technology content.
