摘要
两优2887(NC228S/R187)是湖北省农业科学科院粮食作物研究所育成的两系杂交粳稻组合。根据两优2887多年多点制种实践,并结合双亲的主要特征特性,总结了该组合母本直播高产制种技术。
Liangyou 2887 is a new two-line japonica hybrid rice combination crossbreed from the male line R187 and the PGMS line NC228S. This combination was bred by Institute of Food Crops, Hubei Academy of Agricultural Sciences. Based the seed practice of Liangyou 2887,its high- yielding seed production techniques by direct seeding of the female parent were summarized in this paper.
