This work aimed to assess the resistance of soybean genotypes to Meloidogyne javanica under field and greenhouse conditions. Genotypes CEPsRR 07224, CEPsBt 09036 and CEPsBt 10129 had the lowest gall intensity values under field conditions. Only genotype CEPsRR 07224 classified as resistant and the others were classified as moderately resistant in field. Genotype CEPsBt 10129 had the lowest value for number of galls and gall index under greenhouse conditions, and did not differed statistically from the resistant standard BRS 256RR. All genotypes showed RF> 1, and genotypes CEPsBt 09033, CEPsBt 09036 and CEPsBt 10129 had the lowest number of eggs and reproduction factor. Nevertheless, when using gall index and reproduction factor as evaluation criteria, both CEPsBt 09036 and CEPsBt 10129 performed as tolerant in field and greenhouse conditions.
