Abstract:

Zhongzheyou 26 is a new high-quality hybrid rice variety bred by Zhejiang Wuwangnong Seed Industry Co., Ltd. and China Rice Research Institute using Zhongzhejiang 2A and F1436, which passed the national registration and Guangxi Zhuang Autonomous Region registration in 2020. Zhejiang Longyou Wuguxiang Seed Industry Co., Ltd. introduced Zhongzheyou 26 for experimental planting in 2019, and the field trail showed good yield, high quality, fertilizer tolerance and lodging resistance, and strong resistance to white leaf blight and rice blast. At the same time, 2 years of Zhongzheyou 26 seed production work was carried out in Longyou. Based on the field performance and seed production practice of Longyou, Zhejiang, combined with the characteristics of the parents, a safe and high-yield seed production technology suitable for Zhongzheyou 26 in western Zhejiang was proposed.

Key words: hybrid rice, Zhongzheyou 26, characteristics, seed production technology
