FIELD EVALUATION OF RICE LINES FROM IRRI AGAINST BACTERIAL LEAF BLIGHT IN THUA THIEN HUE – VIETNAM

 Summary: : Xanthomanas campestris pv. oryzae is a causal agent of rice bacterial blight, a destructive rice disease worldwide. This disease is widely spread in Vietnam. Many people have attempted to control this disease by chemical sprays. However, there are claims and counterclaims about the performance of many chemicals because they are hazardous to humans and environment. The most accepted and promising strategy is breeding resistant cultivars. In this study, 64 rice lines provided by IRRI were evaluated for the resistance to bacterial leaf blight in Thua Thien Hue province of Vietnam. The experiments were laid out in a completely randomized design (CRD) without replications in the Spring-Summer crop of 2015 in the open field at district Quang Dien, Thua Thien Hue province. The results showed that rice lines were highly resistant with bacterial leaf blight. The IR 12 line performed the highest resistant level to bacterial leaf blight. Based on the agronomic traits and level of bacterial leaf blight resistance, IR 3, IR 4, IR 46, IR 28, IR 6, IR 18, IR 14 and IR 26 lines were selected for the breeding program
