Abstract:

Jiayou 10 is a new three-line hybrid japonica rice variety developed by crossing the BT-type early-maturing medium japonica male sterile line Jia 57A with the restorer line Jiahui 10. This variety exhibits excellent comprehensive disease resistance, superior grain quality, and high seed production yield. It was approved by the Shanghai Municipal Crop Variety Approval Committee in 2022. This paper analyzed the agronomic traits, yield performance, grain quality, and disease resistance of Jiayou 10. Additionally, the key cultivation techniques and seed production techniques for this variety were summarized, providing a theoretical basis for its popularization and application.

Key words: hybrid japonica rice, Jiayou 10, high quality, disease resistance, breeding
