The fusariose is the most severe disease in pineapple in Brazil and the most planted cultivars, ‘Perola’ and ‘Smoth Cayenne’, are susceptible, with estimated losses of 30 to 40% of the fruits. The use of disease resistant genotypes opens great prospects for resolving the problem. The objective of this research was to study, in a field experiment, the potential of production, the plants characteristics and the fruit quality of new pineapple hybrids resistant to fusariose: EC-105, EC-93, cv. BRS Vitória and cv. BRS Imperial comparing the performance of these genotypes with the cultivars ‘Pérola’, ‘Smooth Cayenne’ and ‘Gold (MD-2)’, susceptible to the disease. The experimental design was completely randomized blocks, with five replicates. The cv. BRS Imperial features important fruit quality, with higher values of SS and ratio. The cv. BRS Vitoria brings together favorable characteristics as mass of fruit similar to the Pérola cultivar, reduced diameter of the central axis of the fruit, low rates of adherence of slips to fruit and fruit overturned, production of good number of profitable slips. The other hybrids resistant to fusariosis show negative characteristics that limit its recommendation to commercial cultivation.
