参阅了 1996～ 19983ａ 18期《杂交水稻》杂志(见表 1) ,并结合近期的有关资料 ,综述三系杂交稻育种概况。1　早、中、晚组合3ａ 18期刊载的通过省级审定的组合共 32个 ,其中中晚稻组合 2 6个 ,早稻组合 6个。这说明中、晚稻接班组合较多 ,而早稻组合相对较缺。还说明科研单位 See the 1996 ~ 19983a 18 issue of “hybrid rice” magazine (see Table 1), and combined with recent relevant information, overview of three-line hybrid rice breeding overview. A total of 32 provincial-level approved combinations of early, middle and late combinations of 3a and 18 were obtained, of which 26 were middle and late rice combinations and 6 were early rice combinations. This shows that there are more successors of late rice combinations, while the relatively early rice combinations are relatively lacking. Also note that scientific research units
