| Abstract: | Resistance identification of 65 introgression lines derived from wild species of Oryza of IRRI was carried out to examine their resistivity to Rice Blast,Bacterial Blight and Brown Planthopper. Among the 65 lines,34 lines were screened which resisted Rice Blast ;15 lines resisted highly and 35 lines resisted fairly to Bacterial Blight ; 3 lines had a high and 44 lines had a middle resistivity to Brown Planthopper, and 18 lines showed facultative resistance to two pests or deseases and 27 lines had a facultative resistance to three pests or diseases . Above resistant lines were screened to be expected to provide new resistance resources for rice breeding. |
