Bacterial blight (BB) disease of rice, caused by Xanthomonas oryzae pv. oryzae (Xoo), is one of the most serious diseases in all major rice-growing areas of Thailand. The most effective approach to control BB is the use of resistant varieties. However, the selection pressure from the usage of resistant cultivars may result in mutation of the pathogen population to overcome the resistance genes. Therefore, using genetic resources conferring different resistance genes are more advantage in rice improvement. The aim of this research was to survey and screen BB resistance genes in Thai local rice varieties from the National Rice Seed Storage Laboratory for Genetic Resources to gain more genetic diversity for resistance. In this study, the Thai Local rice... |
