国家杂交水稻工程技术研究中心在两系法杂交早稻研究中取得新突破。在该中心试验田中，采用亚种间杂交的早稻新组合早D／D34实种结果测算，亩产达到1026斤，生长期为105·天，稻谷品质达部分优质米二级标准。中心主任、中国工程院院士袁隆平研究员认为，早S／D34新组合的成功， National Hybrid Rice Engineering Research Center made new breakthroughs in the study of two lines of hybrid early rice. In the experimental field of the center, using early D / D34 seed combination of early-season hybridization between subspecies as a result, the yield per mu reached 1026 kg and the growing period was 105 days, and the quality of some rice reached Grade II standard of high quality rice. Center director, academician Yuan Longping Chinese Academy of Engineering researchers believe that the success of the early S / D34 new portfolio,
