The effect of plant mortality (M) caused by the Fusarium wilt/Meloidogyne incognita (Mi) complex on cotton cultivars grouped by susceptibility to Mi. All susceptible cultivars to Mi, with the exception of Fibermax® (FM) cultivars ◯; FM-conventional cultivars ■; FM-transgenic cultivars ◻; Mi-resistant cultivars ▲. A quadratic model based on plant mortality was fitted to yield.

Models were fitted to lint yield collected from Fusarium wilt/Mi disease complex fields in four counties (six trials total). The best fitting factor [percentage mortality (M), transformed Mi (LMi)] was fitted to each location. Mi-susceptible ◻, Mi-resistant Fibermax ◼, ST 4946GLB2 ▲, ST 5600B2XF ◊, Mi-resistant Deltapine ×, and Mi-resistant Phytogen ● are shown for each County trial(s). A list of Mi-resistant cultivars is found in Table 2. A list of all cultivars in each trial is in Appendix 1. Mi, Meloidogyne incognita.
