Identification and Screening of Resistance to Rice Bacterial Blight in Common Wild Rice Hybrid Offspring

In order to exploit excellent wild rice resources resistant to rice bacterial blight(Xanthomonas oryzae pv.oryzae)and attain the purpose of controlling rice bacterial blight,we identified and investigated the resistance to rice bacterial blight of different lines in different generations of Hexi 35 × Yuanjiang common wild riceoffspring in different years,and obtained some rice materials with middle or high resistance to rice bacterial blight,which will provide basis for the mapping of the gene highly-resistant to rice bacterial blight and rice disease-resistant breeding in the future.
