Summary: | Rice is the most consumed food crop around the globe. Bacterial blight (BB) caused by <i>Xanthomonas</i> <i>oryzae</i> pv <i>oryzae</i> (Xoo) is the most destructive bacterial disease in rice. The cross CB 87 R × (CB 87 R × IRBB 60) was screened for three BB resistance genes <i>Xa</i>21, <i>xa</i>13 and <i>xa</i>5 with the help of molecular markers revealed 15 individuals found to have resistance genes. The identified individuals with <i>Rf</i> gene were considered as an important criterion in the high yielding background, and the stabilized individuals could be used as genetic stocks for disease resistance breeding program in rice.
