Abstract: Sixty rice varieties and germplasm resources introduced from IRRI and fifty from China were researched and evaluated to rice bacterial blight, blast disease and main agronomic traits in 2006~2007 in Guangxi. The result showed that there were twenty-three varieties with high to moderately resistant to bacterial than the others. Accounting for 20.91% of the total evaluated varieties; and eighteen varieties with resistant to blast, accounting for 16.36% of the total evaluated varieties. At the last, seven varieties were selected with resistant to bacterial blight and blast disease, and their main agronomic traits had a great discrepant. It was indicated that there were diversified hereditary for these resources. So, it is very high value in using them to breeding new varieties (combinations) with high yield and disease resistant.
