Abstract

Abstract:

The late japonica rice variety Xiushui 121 was developed by Jiaxing Academy of Agricultural Sciences in Zhejiang Province through hybridization of Xiushui 134//Xiushui 134/GF6. It was approved by Shanghai Main Crop Variety Approval Committee in 2015（Hushendao2015005）and has been introduced and promoted in four provinces including Zhejiang Province（Zheyinzhong2017001），Anhui Province（Wanyindao2018117），Hubei Province（Eyinzhong2019087），and Jiangsu Province（Suyinzhong2020036），demonstrating wide adaptability. This variety has the characteristics of moderate growth period，green stem at maturity，strong stress resistance，excellent grain quality，stable yield performance，and high productivity. It is widely used in branded high-quality rice processing and the "Five-Excellence Linkage" contract grain production program，and has been consecutively listed as a leading crop variety in Zhejiang Province for six years（2019-2024）. This paper summarizes the breeding process，characteristics，high-yield cultivation techniques，and promotion and extension of Xiushui 121.

Key words: high-quality late japonica rice, Xiushui 121, characteristic, cultivation technique, extension and application
