Abstract: Fusarium wilt is one of the main diseases that seriously restrict the yield of common bean in China. In this study, the hypocotyl double hole injection method was used to identify the resistance of 601 common bean germplasm resources to fusarium wilt, and 4 highly resistance materials were screened out. Based on 3 765 456 single nucleotide polymorphisms (SNPs) distributed on the whole genome, the genome-wide association study was conducted with P<1×10-5 as the threshold. A total of 57 significant SNPs were detected, which are distributed on chromosomes 1, 2, 6, 8, and 11 respectively. A total of 8 significant associated regions were obtained, of which region 1 on chromosome 1 contained up to 48 SNPs and the most significant SNP P value was 2.18E-07. Furthermore, 186 genes were detected in 8 significant association regions, of which 157 were annotated genes, including encoding peroxidase, disease resistance protein, transcription factor and protein kinase genes. Combing KEGG enrichment analysis and homology comparison, 9 candidate genes were identified that might be related to resistance.
