Bacterial wilt is the most destructive disease for many plants in the Solanaceae family. Bacterial wilt in peppers (Capsicum spp.) is caused by Ralstonia solanacearum. To identify potential sources of resistance, the G2PSol Capsicum core collection and Gene bank accessions from the World Vegetable Center in Taiwan was evaluated using a high throughput laboratory based bacterial wilt screen. The resulting phenotype data was combined with existing genotype data to identify marker trait associations (MTAs) as part of a larger genome wide association study (GWAS). Population structure was estimated to account for the number of ancestral populations using PCA and structure analysis. MTAs were identified on chromosomes 1, 2, 4, 6, 7, 10 and 11 with the most significant being on chromosomes 4, 7 and 11. Future work will focus on screening the rest of the Capsicum core accessions, comparing the lab results with greenhouse and field results and re-analyzing the data with high density SNPs.
