| Abstract: | Six combinations and 14 restorer lines of two line japonica hybrid rice were identified for their resistance to rice blast. The results showed that among the combinations, Yunguang 9, 70 You 9 and 70 You 04 were highly resistant (HR) and Yunguang 8 was moderately resistant (MR); among the restorers, Dongfan 1, Dongfan 4, Dongfan 23 and Dongfan 85 were HR and Dongfan 2, Dongfan 3, Dongfan 5, Dongfan 47, Dongfan 54 and Dongfan 86 were MR. |
