夏收之际,从坐落在长沙市东郊的国家杂交水稻工程技术研究中心传出令人振奋的消息:在该中心试验田中,采用亚种间杂交的早稻新组合早S/D34实种结果测算,亩产达到513公斤,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,是两系法早稻研究的一个新突破,使杂交早稻 On the occasion of summer harvest, we heard encouraging news from the National Hybrid Rice Engineering Research Center located in the eastern outskirts of Changsha: In the experimental field of the center, the results of the early S / D34 seed combination of early rice with inter-subspecific hybridization , 513 kilograms per mu, the growth period of 105 days, rice quality of some high-quality rice two standard. Researcher Yuan Longping, director of the Center and academician of Chinese Academy of Engineering, believes that the success of the early S / D34 new combination is a new breakthrough in the study of two lines of early rice, making hybrid early rice
