Ten cotton ( Gossypium hirsutum L.) cultivars were evaluated under five environments to determine their reaction to Fusarium wilt ( Fusarium oxysporum f. vasinfectum (Atk.) Snyd & Hans.) and root‐knot nematodes ( Meloidogyne spp.). These tests were conducted in an effort to determine a set of entries with known differential susceptibility to the Fusarium wilt‐root‐knot nematode complex. ‘Auburn 56’ and ‘Auburn M’ were highly resistant, while ‘Rowden’ and ‘Stardel’ were highly susceptible under all environments. The other six cultivars differed over environments but usually were intermediate in resistance. Although a complete set of differentials was not determined, two distinctively different groupings were observed. Using a cultivar from both the resistant group and the susceptible group as check materials hi Fusarium wilt screening tests will enable investigators to compare results from different areas on a relative basis.
