Abstract

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
