Abstract: A new variety of photosensitive hybrid rice, Yuanyou 2105, was bred by crossing the 3-line male sterile, Yuanfeng A, developed by Sanming Academy of Agriculture Science and the restorer line, Fuhui 2105, developed by Fujian Agriculture and Forestry University. It was certified by Fujian Crop Variety Evaluation Committees in 2016. The growing period of the new variety was approximately 160 d, which was 20 d longer than that of comparable mid-season varieties. The breeding procedure and characteristics of Yuanyou 2105 are presented.
