我国水稻育种专家、中国工程院院士袁隆平近日透露,我国的水稻育种将迎来第三次突破。即利用水稻亚种间杂种优势的研究现已取得重大进展,预计在近期内,具有更强大杂种优势的两系法亚种间杂交水稻就能培育成功,其产量潜力要比现行的杂交水稻高15％～20％。 农业生产和作物育种的研究表明,凡在育种上有所突破,就会给农业生产带来 Yuan Longping, a rice breeding expert and academician of the Chinese Academy of Engineering, recently disclosed that China’s rice breeding will usher in the third breakthrough. That is, great progress has been made in the study of the heterosis among rice subspecies. It is expected that the two-line subspecies hybrid rice with more powerful heterosis will be successfully cultivated in the near future and the yield potential will be higher than that of the current hybrid rice 15% ~ 20%. Research on agricultural production and crop breeding shows that where there is a breakthrough in breeding, it will bring about agricultural production
