Resumo: | The resistance of ten genotypes of pineapple to two nematodes species, Meloidogyne javanica and Pratylenchus brachyurus, was evaluated in two experiments at greenhouse. Each one of them was completely randomized with six replications. The cultivar Smooth Cayenne was used as a susceptible control. Each plot was represented by one plant/pot. Each pot held 4 l of soil previouly sterilized with metil bromide. Pineapple seedlings were inoculated, two months after planting, with 1,000 juveniles (J2) of M. javanica at the first experiment and 1,000 individuals of P. brachyurus at the second experiment. Taproot weight, eggs masses, nematodes per plant and reproduction rate were recorded 90 days after inoculation. The resistance selection was based on the percentage of the reproduction rate. The genotypes FRF- 632 and H- 3607 had minor resistance to M. javanica (PR) and LBB- 1385, Primavera, FRF- 609 and LBB- 1396 presented moderated resistance (MR). The genotypes H- 3607, LBB-1396, Perolera, FRF- 609 and Primavera had minor resistance to P. brachyurus (PR). KEY-WORDS: Ananas comosus; resistance; root knot nematode; root lesion nematode. |

Dez genótipos de abacaxi foram avaliados para resistência às espécies de nematóides, Meloidogyne javanica e Pratylenchus brachyurus, em dois experimentos conduzidos em casa de vegetação, seguindo o delineamento inteiramente casualizado com seis repetições, empregando o cv. Smooth Cayenne como padrão de suscetibilidade. Cada parcela foi constituída de uma planta/vaso, contendo solo esterilizado com brometo de metila. Após dois meses do plantio das mudas, as plantas foram inoculadas com 1.000 juvenis (J2) de M. javanica no primeiro experimento e 1.000 indivíduos de P. brachyurus no segundo experimento. Após 90 dias da inoculação foram avaliados os seguintes parâmetros: peso do sistema radicular, número de ovos e de nematóides por planta e fatores de reprodução. A seleção para resistência foi baseada na percentagem de redução do fator de reprodução. Em relação a M. javanica, os genótipos FRF-632 e H-3607 foram pouco resistentes (PR) e os de LBB-1385, Primavera, FRF-609 e LBB-1396 comportaram-se como moderadamente resistentes (MR). Para P. brachyurus foram selecionados como pouco resistentes (PR) os genótipos de H-3607, LBB-396, Perolera, FRF-609 e Primavera.
