Bacterial streak (BS) caused by Xanthomonascampestris pv. oryzicola has become one of themajor diseases in southern rice areas. Up todate, there are few reports on the inheritanceof resistance to BS and its relationship with theresistance to bacterial blight (BB). Therefore,we analyzed the inheritance of resistant to BSin three resistant rice cultivars and the geneticrelationship of resistance between BS and BB.
