Three cultivars of sweet potato (Ipomoea batatas Lam.) were grown at 7 production sites in Mississippi during 1959 and 1960, using plants from a common source. Forty U.S. No. 1 roots of each cultivar at each production site were sampled and carbohydrate and carotene content determined. Variation in carotene content was much greater among cultivars when compared to variation among production sites, however, there were highly significant differences within a cultivar among the various production locations. Carbohydrate content within a cultivar varied among production sites more than among those at any one production site. The feasibility of establishing a nutrient content range for fresh vegetable products is highly questionable.
