作物优势利用现状及构想

The Present Condition and Conception of Crop Heterosis Utilization

回顾了作物杂种优势和多倍体优势利用的研究情况,针对目前作物产量徘徊、优势潜力难以发挥的现状,提出了作物层次优势利用的构想,即作物优势利用发展3个阶段:二倍体杂种优势利用、多倍体杂种优势利用和功能基因优势利用。

This paper reviewed the research progress on utilizations of crop heterosis and polyploid advantage, and proposed conception of crop arrangement advantage in accordance with crop yield fluctuation and the hard situation to give full play of the advantage potential. The conception contains three developmental phases on utilizing crop advantage: diploid heterosis utilizing phase, polyploid heterosis utilizing phase, and functional genes advantage utilizing phase.
