The population structure of Hemileia vastatrix in Brazil inferred from AFLP
Maia, T. A.; Caixeta, E. T.; Mizubuti, E. S. G.; Zambolim, L.; Maciel-Zambolim, E.Efforts to obtain durable resistant cultivars to coffee leaf rust have a long history of disappointment because of the lack of information on the Hemileia vastatrix evolutionary potential. In this study, the AFLP marker was used to analyze the genetic structure of a field population of H. vastatrix from different coffee genotypes cultivated in a wide geographic region of Brazil’s main production areas. A total ...
Climate favourability to leaf rust in Conilon coffee
Capucho, A. S.; Zambolim, L.; Cabral, P. G. C.; E. T. Caixeta; Maciel-Zambolim, E.The Brazil is the second largest producer of Conilon coffee (Coffea canephora), being the state of Espírito Santo responsible for producing 9.7 million bags of Conilon coffee. The biology of Hemileia vastatrix, etiologic agent of leaf rust, the main disease of this culture, is not well understood under the environmental conditions of Espírito Santo, Brazil. This study determined the ideal temperature and leaf w...
