Reação de genótipos de milho (Zea mays L.) aos nematóides de galhas (Meloidogyne javanica e M. incognita)

Abstract

Two experiments were carried out under greenhouse condictions with the objective of evaluating the rcaction of cight com genotypes to the root-knot nematodes Meloidogyne javanica and M incognita. Cultivars HATÃ-1001, HATÃ-1045, DINA-657 and FT-5140 presented smaller reprodution factors (RF) for M. jdvanica. Theréfore, the use of these cultivars may be indicated in the crop rotation program with soybean. Ali cultivars were suitable hosts for M incognita, presenting RF higher than 3.98.
