Breaking Transgressive Photoperiod Sensitivity Barrier Triggered by Breeding Introgression of Pigm in Early-Mature Geng/Japonica Rice
Heilongjiang and Jilin's early-maturing Geng / japonica (EMG) rice—grown at the world's northernmost latitude—delivers 17.3% of China's rice grain from only 16.0% of the national paddy area, yet every newly approved cultivar must combine early heading (EH) and blast resistance (BR).
