“…In 1987 and 1989, the occurrence of the disease was observed by Schwartz et al (1989) in production fields of the cultivated variety Pinto, in the State of Colorado (USA), under conditions of high temperature, low availability of water, and compacted soil (Buruchara & Camacho, 2000). In Brazil, the first report of Fop was in the municipality of Laranjal Paulista, São Paulo state, with typical symptoms of the disease in the Rosinha variety (Cardoso et al, 1966). Subsequently, it was disseminated in several regions of Brazil (Toledo-Souza et al, 2012).…”

Sustainable management of plant diseases has been a challenge in the effort to feed a human population that has increased substantially. One of the main diseases that affect common bean and dry bean is Fusarium wilt, caused by the fungus Fusarium oxysporum f. sp. phaseoli (Fop), which can cause losses of up to 100% in crop production. The Fop infection process starts in the roots, followed by colonization and obstruction of xylem vessels, leading to leaf wilting, vascular discoloration, chlorosis, dwarfism, and premature plant death. Fop show high genetic variability, and seven different physiological races have been reported in different regions of the world. There is also a study in which the formae specialis designation has been replaced by Fusarium species. Different studies in common bean have shown that physical, biological, and chemical changes are involved in the Fop resistance mechanism and in the Fusarium and common bean pathosystem. Many studies have been conducted to detect candidate genes and pathways associated with resistance to Fop. This work offers useful information for advancing common bean resistance breeding.

“…A infecção pode ocorrer em qualquer época do ciclo da planta, principalmente quando jovem (Tuset- Barrachina, 1973). Sua incidência ocorre em reboleiras (Mohan et al, 1983), podendo levar a planta à morte (Cardoso et al, 1966;Costa et al, 1982e Pastor-Corrales & Abawi, 1987.…”

Fusarium wilt, caused by the fungus Fusarium oxysporum f. sp. phaseoli, is one of the most prevalent diseases in the common bean crop (Phaseolus vulgaris). However, there is little information regarding the genetics of reaction to this disease. Thus, the aims of this study were to estimate genetic parameters, identify quantitative trait loci (QTLs) associated with reaction to Fusarium wilt, and validate the markers identified. A total of 165 progenies of the population BRS FP403 × BRS Horizonte were evaluated. Evaluation was made in 2016 and 2017 in field trials in an area infested with the pathogen in Santo Antônio de Goiás, Brazil. Genotyping of single nucleotide polymorphism and SilicoDArT, where DArT is Diversity Arrays Technology, markers using the DArTseq technology was performed in the F2 generation. Analyses of the phenotypic data indicated the presence of variability among the progenies and the possibility of success from selection, with high estimates of heritability (90%) and gain from selection (37%). A genetic map was obtained with 702 markers and spanned 3069 cM. Five QTLs associated with reaction to Fusarium wilt were identified on five chromosomes. There was interaction between the QTLs and years. Through joint analysis, four QTLs were identified on chromosomes Pv01, Pv02, Pv03, and Pv04, explaining 5.8%–40.5% of the variation. The QTL FOP2.3403H explained 40.5% of phenotypic variation and was stable over the 2 years. From this QTL, two hydrolysis probes were developed for genotyping in a panel of lines for validation. Selection efficiency was over 92%, indicating considerable potential for use in marker‐assisted selection.
