Fusarium wilt of banana, caused by the soil-borne pathogen Fusarium oxysporum f. sp. cubense (Foc), is one of the most devastating diseases of this crop. No sustainable control strategy exists other than replacing susceptible cultivars with cultivars resistant to the disease. Identification of resistance sources is thus an essential step in breeding programmes. In Brazil, this is not only important for Musa genotypes used for consumption, but also for those used for ornamental purposes. In this work, 28 Musa genotypes with the aim to: a) identify sources of resistance and b) characterise promising genotypes for disease resistance. Ten plants of each genotype were planted in an area highly infested by For races 1 and 2 using a completely randomised design. As susceptible control, 'Silk' (AAB) plants were placed between each individual. Disease severity was assessed monthly by means of a scale based on external symptoms ranging from 0 to 4 (0: healthy plant and 4: dead plant). In addition, harvested plants were evaluated for rhizome discoloration. Most of the 'Silk' plants (96%) showed symptoms of the disease, confirming the high inoculum pressure in the area. Highly resistant genotypes were identified in all ploidy levels. Most of the diploid genotypes were classified as resistant. Among them, 'NBA-141' (AA) was highlighted, since it produces commercial fruits with high carotenoids contents. Hybrids, such as 'PA94-01' (AAAB) and 'FHIA-02' (AAAA) were also ranked as resistant. These genotypes are promising for direct cultivar selection , integression of resistance alleles in susceptible genotypes, as well as to elucidate the genetic basis os resistance to Fusarium wilt in banana.
