摘要: 沪优71是以虾稻1号为父本、沪旱7A为母本选育的三系杂交水稻新品种,于2024年通过湖北省农作物品种审定委员会审定。该品种产量高、米质优、稻瘟病抗性好、再生性好,同时通过了湖北省晚籼稻和再生稻联合体区域试验。针对其特征特性,建议该品种在栽培上应根据需要适时播种,作再生稻种植应选择合适的留桩高度,同时控氮增钾,提高抗倒性。

Abstract: Huyou 71 was a new three-line hybrid rice variety developed using Xiadao No.1 as the male parent and Huhan 7A as the female parent. It was approved by the Hubei Provincial Crop Variety Approval Committee in 2024. This variety demonstrated high yield potential, excellent grain quality, strong resistance to rice blast, and robust ratooning ability. It has also passed the joint regional trial for late indica rice and ratooning rice in Hubei Province. In view of its characteristics, it was considered that the cultivation of this variety should be sown in time according to the needs, and the suitable height of stubble should be selected for the cultivation of ratooning rice. At the same time, nitrogen should be controlled and potassium should be increased to improve lodging resistance.

Key words: late-season rice, ratooning rice, Huyou 71, breeding, application
