Fusarium wilt of banana (also called as Panama disease) caused by the soil-borne fungus, Fusarium oxysporum f. sp. cubense (Foc) is a major factor limiting commercial banana production worldwide. There is no known chemical or cultural method available to effectively control the pathogen. Susceptible varieties need to be replaced by resistant cultivars for sustainable banana production. Genetic improvement has to play an important role in order to transfer disease resistance alleles to the genetic background of elite genotypes. However, banana breeding is a complex and time-consuming process and the screening methodologies have to be efficient and reliable to avoid or reduce the selections of false19 resistant genotypes. The most common methods of selection involving screening genotypes in field with historic of high Fusarium wilt incidence. However, field evaluation of banana plants for Fusarium wilt disease can be not effective, since the infection period is slow and other variables such as distribution of inoculum concentration and interaction with other soil microorganism are difficult to control. In order to minimize this, at Embrapa Cassava and Tropical Fruits a screening area was intentionally infected with Foc by planting successively the highly susceptible variety 'Maçã' (Silk) and spreading the inoculum by tillage (Cordeiro et al. 1993). Despite of susceptible cultivar Maçã, always used as control, shows high levels of incidence (up 90 %), each season some plants of this cultivar remains without symptoms, suggesting a no homogeneous inoculum distribution and the possibility of 29 escape occurrence in the germplasm screened.
