【摘要】 近年来,我国水稻面积和稻谷总产量持续下降,已引起广泛关注。面对人增地减,农产品市场竞争激烈的双重压力,中国的杂交水稻育种只能走高产与优质并重的道路,培育优质超高产水稻品种——中国泰米。目前,杂交香稻育种已取得较好成绩,为该目标的实现奠定了基础。未来中国超高产泰米品种(籼稻)不仅在中国亚热带稻区种植,而且可望在南亚和东南亚热带稻区广泛应用,以大幅度增加亚洲水稻总产和进一步改善稻米品质。这对于保障中国和世界粮食安全均具有现实意义。更多还原

【Abstract】 In resent years, with the continuous drop of the rice planting area and grain output in China,ithas widely drawn the attention. Facing with the double pressures of increasing population while decreasingland area and the furious market competition for farm products, the unique hybrid rice breeding orientation inChina has to take the way with both high yield and fine quality to develop super Thai-rice. Nowadays,aromatic hybrid rice breeding has achieved good accomplishment, which makes a base for the realization ofthis target. In future, China super Thai-rice varieties (Indica rice) will be grow not only in subtropical paddyfields but very much possible in south and soulheast Asian paddy fields extensively as well. Hence, it canenhance the total rice yield in Asia, and further improve rice quality It is of great importance for guaranteeingfood security in China and all over the world as well.更多还原
