The aim of this study was to evaluate the behavior of new varieties of Coffea arabica in an area naturally infested with Meloidogyne incognita. The experiment was conducted in a sandy soil area in the north-east of Parana, Brazil, in a randomized complete block design, with ten repetitions per treatment. Each plot contained four plants per row, 0.75 m apart, and four rows 2.7 m apart. The treatments used were the coffee cv. IPR 100 and IPR 106, as well as the non-grafted Iapar 59 (susceptible) and the grafted Apoatã 2258+Iapar 59 (resistant). The planting and execution of the experiment were carried out following standard cultivation recommendations. Height measurements and nematode population recordings were taken at 17 and 30 months after planting and productivity was evaluated at harvest time. On first evaluation, the cultivars IPR 100 and IPR 106 presented lower numbers of eggs+J2 per root system when compared to the cultivar Iapar 59. The second evaluation showed improvements in plant size, in which the cultivars IPR 100 and IPR 106 showed the greatest plant-height and yield, varying between 233 to 347 % compared to the susceptible cultivar. However, the number of eggs+J2 was greater in the IPR cultivars at the second evaluation.
