RESUMO:

Common beans (Phaseolus vulgaris L.) are grown worldwide and one of the phytosanitary problems that compromise grain quality and productivity is the pathogen Sclerotinia sclerotiorum (Lib.) de Bary, a fungus that causes white mold. The objective of the study was to select common bean genotypes with a physiological resistance reaction to the pathogen that causes white mold and to identify candidate genomic regions associated with this characteristic. For the selection of parents, the reaction to the disease was evaluated in a panel composed of 114 genotypes using the straw test and seedling straw test inoculation method. The genotypes were genotyped via GBS and obtained, after MAF of 0.05, 28,823 high quality SNPs, using them for associative mapping through the MLMM, FarmCPU and BLINK models. Given the complex nature of physiological resistance, genotypes BL10, BL15, BL18 and BL95 were selected, indicated by both methods used, suggesting a high level of physiological resistance. The regions associated with the physiological resistance characteristic were indicated on chromosomes Pv02, Pv03, Pv09 and Pv10, indicating the presence of the QTL already reported WM2.2 BV, R31 and WM3.1AN, XC, AP in addition to the annotation of genes related to resistance to biotic stresses Phvul.002G023400, Phvul.009G230200 and Phvul_009G232100, in the associated regions, providing candidate genes for validation studies.
