    袁隆平關于雜交水稻育種的論述

    時間:2011-6-9 9:19:49 點擊:

        育種家必須要有清醒的認識,迄今為止,通過育種提高作物產量,只有兩條有效途徑:一是形態改良,二是雜種優勢利用。單純的形態改良,潛力有限;雜種優勢不與形態改良結合,效果必差。其它育種途徑和技術,包括分子育種在內的高技術,最終都必須落實到優良的形態和強大的雜種優勢上,從而才能獲得良好的效果。

        It will clarify our thinking if we plant breeders realize that, up to now, there are only
    two effective ways to increase the yield potential of crops through breeding, i.e., morphological improvement and heterosis utilization. However, he potential is very limited by using morphological improvement alone and heterosis breeding will produce undesirable results if it does not combine with morphological improvement. Any other breeding approaches and methods including high technology like molecular breeding must be incorporated into good morphological characters and strong heterosis, otherwise there will be no actual contributions to yield increase.
