Day‐neutral plants of selections from the primitive cotton ( Gossypium hirsutum L.) race collection and from crosses of these with ‘Deltapine 16’ (DPL‐16) were evaluated for resistance to Fusarium wilt [ Fusarium oxysporum Sehlect. f. vasinfectum (Atk.) Snyd. & Hans.]. Yield and fiber properties of advanced material from these crosses were also determined. When evaluated as race stock selections per se, or as advanced generation materials from crosses with DPL‐16, Fusarium wilt resistance of materials with either an accession 69 or 88 background was high. Selections of advanced materials from crosses of DPL‐16 with six other race accessions (78, 80, 87, 113, 116, and 495) were also highly resistant. Based on a I‐year evaluation at one location lint yields and fiber properties of all advanced materials (BC 2 F 4 ) from crosses with DPL‐16 were not statistically significant from those of the two check cultivars (DPL‐16 and ‘Stoneville 213’).
