Abstract

Abstract:

Zheyou 77 is a new indica-japonica hybrid rice variety with long-grain bred by the Institute of Crop Sciences and Nuclear Technology Utilization, Zhejiang Academy of Agricultural Sciences, Guzhiyu (Huzhou, Zhejiang) Agricultural Technology Co., Ltd., and Hangzhou Seed Industry Group Co., Ltd. It has the characteristics of high yield, excellent rice quality, good color conversion, etc. It has been approved by Zhejiang Crop Variety Committee in 2024. It is suitable for single season late rice planting in Zhejiang Province. In order to accelerate the popularization of the new indica-japonica hybrid rice variety Zheyou 77 and improve the seed production yield of the new variety, the parental characteristics and high yield and efficient seed production technology of Zheyou 77 were introduced in this paper.

Key words: Zheyou77, long grain indica-japonica hybrid rice, high yeild, seed production
