Hybrid late japonica rice restorer lines successfully bred in the Yangtze River Basin
Through the efforts of experts from the Shanghai Academy of Agricultural Sciences, the "Yangtze River Basin hybrid late japonica rice restorer lines - Shenhui 254 and Shenhui No. 1" were successfully bred and utilized. This project was awarded first prize for scientific and technological progress by the Shanghai Municipal Government this year. The key to applying hybrid late japonica rice in production in the Yangtze River Basin is to breed excellent late japonica-type restorer lines. This project used intermediate materials between indica and japonica subspecies as bridge parents, introduced indica restorer genes into late japonica rice varieties, adopted convergent crossing and systematic selection, and gathered the excellent base
