The objectives of this study were to evaluate resistance to Meloidogyne enterolobii in a Psidium hybrid and its compatibility as rootstock for two guava cultivars in order to be commercially released. Materials and methods ? The treatments consisted of guava cv. Paluma scions without grafting, hybrid scions without grafting, and hybrid scions as rootstock for ?Paluma? and ?Pedro-Sato? guava cultivars. The number of eggs and juveniles of M. enterolobii in the soil and roots, guava decline symptoms, plant architecture, and fruit production were evaluated up to 24 months after transplanting (MAT). Results and discussion ? The infestation by eggs and juveniles in the roots of ?Paluma? differed from infestation in the roots of the hybrid in five evaluation times, except at 6 MAT. The highest infestation by juveniles in the roots for all treatments occurred at 24 MAT, when the magnitude of the infestation in ?Paluma? was almost 540 times higher than the average infestation of the hybrid. The guava cultivars grafted onto the hybrid had fruit yield of approximately 40 t ha-1 at 30 MAT,which was 10 times higher than that of the cv. Paluma without grafting. Stem diameter and canopy width were higher (P<0.01) for the cultivars grafted onto the hybrid compared to the ?Paluma? scion. conclusion ? Guava decline symptoms in ?Paluma? without grafting ranged from severe to plant death, whereas only one plant of the hybrid had moderate guava decline. The hybrid has proved to be resistant to the pathogen and showed excellent compatibility as rootstock for guava cultivars; it should be used as an alternative management practice for preventing damage from this nematode.
