Abstract:

Jiaheyou 7245 is a new three-line hybrid rice variety developed by China National Rice Research Institute, Jiaxing Academy of Agricultural Sciences and Institute of Genetics and Developmental Biology, Chinese Academy of Sciences crossed Jiahe 212A and Zhonghui 7245. This variety boasts features such as an ideal plant type, large panicles with heavy grains, high yield, superior grain quality, and strong disease resistance. It is suitable for cultivation as mid- or late-season rice in the middle and lower reaches of the Yangtze River. After five years of trial planting and demonstration, Jiaheyou 7245 has proven to combine both high yield and superior grain quality achieving a yield of 800.0 kg/667 m2 in Xianju County, Zhejiang Province. It has won the Gold Award for “Good Rice” in Zhejiang Province and Taizhou City on multiple occasions. This variety can enhance the planting benefits and income of grain farmers and has high popularization value. This paper summarizes and analyzes the planting performance, high-quality and high-efficiency cultivation techniques and its prospects for industrialization development.
