袁隆平关于杂交水稻育种的论述

时间:2011-6-9 9:19:49 点击:

    育种家必须要有清醒的认识,迄今为止,通过育种提高作物产量,只有两条有效途径:一是形态改良,二是杂种优势利用。单纯的形态改良,潜力有限;杂种优势不与形态改良结合,效果必差。其它育种途径和技术,包括分子育种在内的高技术,最终都必须落实到优良的形态和强大的杂种优势上,从而才能获得良好的效果。

    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.
