A number of cotton (Gossypium hirsutum) cultivars were evaluated and compared with checks, one susceptible and one resistant to both the wilt fungus (Fusarium oxysporum f. sp. vasinfectum) and root-knot nematodes (Meloidogyne spp.). Based on mean wilting during the last 3 yr, 10 cultivars with tolerance or good resistance to this fungus-nematode complex were identified. Although none was as resistant as the Auburn BR2 check, five cultivars (Deltapine 55, McNair 220, Delcot 311, Rex 713, and Stoneville 603) were highly tolerant.
