The use of nematode resistant crops in rotations prevents losses in susceptiblecrops. The reproduction of Meloidogyne javanica and M. incognita race 3 in maize, sorghumand millet genotypes in greenhouse conditions where evaluated. The plants were grown ingreenhouse conditions, inoculated with 5.000 nematode eggs and evaluated after 60 days.Tomato plants were used as inoculum’s efficiency check. The egg production of M. incognitawas higher than M. javanica in all maize genotypes. M. javanica presented low reproduction(FR<1) in all genotypes. The maize genotypes CMS 100 02 2, HS 723x724, 97 HT 14 A,BRS 3123, BRS 2114, CMS 14 B, CMS 2000 17 A, CMS 99 14 C, 52 HT03-QPM, HS111764040, and all sorghum and millet genotypes were resistant to M. incognita, resulting in low egg production. The commercial resistant genotypes of corn were indicated to nematodeinfested areas.
