摘要:
Bacterial blight, caused by Xanthomonas oryzae pv. oryzae (Xoo), usually causes serious rice yield loss in many countries. Rice breeders have used resistance (R) genes to control the disease but many of the resistant cultivars become susceptible few years after releasing. Identification of new R genes to Xoo is one of the main objectives in rice breeding programs. In this study, we used a genomewide association study (GWAS) to analyse the resistance against the Xoo race C1 using the Rice Diversity Panel 1 (RDP1). Disease evaluation of the RDP1 population to C1 indicated that the AUS subgroup conferred a higher level of resistance to C1 than other subgroups. Genomewide association mapping identified 15 QTLs that are distributed on chromosomes 1, 2, 3, 4, 5, 6, 8, 9, 10 and 12. Some of them are located in the regions without known resistance loci or QTLs. This study demonstrated the effectiveness of GWAS on the genetic dissection of rice resistance to Xoo and provided many Xoo resistance-associated SNP markers for rice breeding.
