Pima and Acala and non-Acala Upland cotton varieties were screened for susceptibility to infection by race 4 Fusarium oxysporum vas infectum in field and greenhouse tests over a two-year period. Evaluations were conducted at one greenhouse location and three field sites in the San Joaquin Valley of California. Data reviewed will include seedling survival percentages and relative impacts on plant growth and vigor, and vascular staining and foliar damage index ratings, with information presented focusing only on commercially-available germplasm tested to date.
