ABSTRACT

The reaction of the yellow passion-fruit cultivars Afruvec and Maguary to Meloidogyne incognita race 2, M. javanica and M. hapla were studied under greenhouse conditions. Three experiments were conducted with similar methodology. The initial population was 5,000 eggs and juveniles of second-stage newly hatched (J2) of M. incognita, M. javanica or M. hapla. The experimental delineations were entirely randomized, with six replications. The evaluated parameters were: gall and egg mass index, roots fresh weight, nematode populations in roots, reproductions factor (FR) and number of nematodes per gram of root. The Afruvec and Maguary cultivars were resistant to Meloidogyne incognita race 2, M. javanica and M. hapla.
