Banana (Musa spp.) is cultivated throughout Brazil, with genotypes varying from region to region. Yellow Sigatoka disease (Pseudocercospora musae) is one of the most common foliar diseases of banana, causing severe losses when it is not properly managed. The objectives of this study were to evaluate banana genotypes for their reaction to yellow Sigatoka infection, and to perform an epidemiological study of this disease to have a better understanding of how it progresses under the environmental conditions of the Brazilian Cerrado. The reaction of 21 genotypes of banana to the infection by P. musae was evaluated in an experiment at Embrapa Cerrados (Planaltina, DF, Brazil), between August 2009 and January 2011, using a diagrammatic scale adapted from Stover, which ranged from 1 (<1% leaf area showing symptoms) to 6 (> 51% leaf area showing symptoms). Assessments occurred every 15 days. At the end of the evaluation period the mean area under the disease progress curve (AUDPC) for each rated material was calculated. Genotypes were selected by Embrapa Mandioca e Fruticultura Tropical and separated into four sets: Cavendish/Gros Michel, Pome-Pacovan, Pome-Prata-anã and Silk/Mysore. An epidemiological study of the disease progress curve for each genotype was carried out to evaluate which non-flexible model (Monomolecular, Logistic, Exponential or Gompertz) would have the best fit to the disease severity progress curve data. Each set revealed genotypes with significant resistance to Yellow-Sigatoka. In the Pome-Pacovan set, resistance was observed in genotypes ‘Vitória’, ‘PV 94–01’, ‘Pacovan Ken’, ‘Japira ‘and ‘PV 79–34′; in the Silk/Mysore genotypes ‘Caipira’, ‘YB 42–03′, ‘YB 42–07′ and ‘BRS Tropical’; in the Pome-Prata-anã set, genotypes ‘PA 94–01′, ‘BRS Platina’ and ‘BRS Garantida’; and in the Cavendish/Gros Michel set the genotype ‘Bucaneiro’. The monomolecular model displayed the best fit, with consistently low mean square error (MSE) values for all banana genotypes presented in this study.
