Description: Fusarium subglutinans, the causal agent of the pineapple fusariosis, is the most serious problem of that crop in Brazil. The cultivation of resistant varieties is the most efficient control measure and this concept is also useful to ornamental plants. This work aimed to evaluate ornamental pineapple hybrids to resistance to fusariosis. Forty hybrids from five crosses (FRF-22 x FRF-1387), (FRF-1392 x FRF-32), (G-44 x FRF-1387), (FRF-1392 x FRF-224) were evaluated. Pineapple slips, about 25 cm long, were wounded at their bases with a needle, 2 mm in diameter, and immersed into a conidial suspension for about three minutes and then transferred to a greenhouse. After 90 days, evaluation was performed considering both internal and external symptoms and a scale of notes was applied. The experiment?s design was a completely randomized one with six replications and two controls: cv. Perola (susceptible) and PEXSC73 (resistant). The results showed that 13 hybrids were resistant, 7 were moderately resistant and 20 were susceptible. Nevertheless, in the cross FRF-1392 x FRF-224 100% of the hybrids was resistant. The behaviour of the controls was adequate to give support to the results obtained in the present work.
