Abstract

Two experiments were carried out under greenhouse conditions with the objective of evaluating the reaction of eight corn genotypes to the root-knot nematodes Meloidogyne javanica and M. incognita. Cultivars HATÃ-1001, HATÃ-1045, DINA-657 and FT-5140 presented smaller reproduction factors (RF) for M. javanica. Therefore, the use of these cultivars may be indicated in the crop rotation program with soybean. All cultivars were suitable hosts for M. incognita, presenting RF higher than 3.98.

KEY-WORDS: Resistance; root-knot; nematodes; corn.
