‘Burgundy’ sweetpotato [Ipomoea batatas (L.) Lam.] was developed by the Louisiana Agricultural Experiment Station to provide an orange fleshed, red-skinned cultivar with superior storage root shape, high sucrose content, disease resistance, and southern root knot nematode resistance. ‘Burgundy’ produces excellent numbers of uniform plants in the plant production beds. ‘Burgundy’ can be harvested up to 10 d earlier than the Beauregard cultivar (Rolston et al., 1987) in the California production region. The two cultivars are similar in harvest days in the Gulf South production region. The roots are elliptical and consistent in shape in varied soil types. It has a superior shape and yields are similar to the red-skinned Diane cultivar for the U.S. #1 grade (5.1 to 8.9 cm diameter, 7.6 to 22.9 cm long) in California. ‘Diane’ is the current dominant red-skinned cultivar in California, and it has a propensity to produce longer roots in the sandy soils typical for the production area; ‘Burgundy’ does not.
Initially identified and evaluated as ‘LA04-175’, the cultivar is named after the deep burgundy–maroon color of its skin.
