Marker-assisted pyramiding of Xa21 and Xa7 genes conferring resistance to bacterial leaf blight in indica cultivar Bacthom7
Bacterial leaf blight (BLB) of rice is one of the most destructive diseases affecting rice fields. Xanthomonas oryzae pv. oryzae (Xoo) is the causal agent of BLB. Two BLB resistance genes, Xa21 and Xa7, were transferred into the susceptible indica cultivar Bacthom7 (BT7) by using marker-assisted selection with markers pTA248 for Xa21 and ID7 for Xa7. Improved BT7 lines carrying the two resistance genes were inoculated...
