Abstract: A new resistance gene to bacterial blight of Xa-23(t) from O. rufipogon was identified based on the resistance spectrum evaluated, comparison of resistance type, inheritance analysis and testing the allelism relationship between Xa-23(t) and Xa-21. The results indicated that it is conditioned by
