在实现第3期单产13500kg/hm2的目标不到两年后,今年5月中旬,随着以“Y两优900”为主的一批主力攻关品种的移栽,中国第4期超级杂交稻攻关正式进入“实战阶段”。目前,Y两优900已在全国布了3个点,分别是湖南省隆回县羊古坳乡牛形村、河南商城县双椿镇王店村和湖北省随县均川镇幸福村。
In less than two years after achieving the goal of yielding 13500kg / hm2 in the third period, in mid-May of this year, with the transplanting of a batch of major research projects focusing on “Y Liangyou 900 ”, No. 4 Super Hybrid rice research officially entered “actual combat stage ”. At present, Y Liangyou 900 has been distributed across the country by three points, namely Niu Xing Village in Yangguo Au Village, Longhui County, Hunan Province, Wangdian Village, Shuangcheng Town, Shangcheng County in Henan Province, and Xingfu Village, Jiachuan Town, Sui County, Hubei Province.
