‘Beauregard’ sweet potato [Ipomoea batatas [L.] Lam.] was developed by the Louisiana Agricultural Experiment Station to combine resistance to diseases and insects of local importance with good horticultural and culinary characteristics. This cultivar, first designated L82-508, is named after Louisiana's renowned civil engineer and “Napo-lean in Grey,” Gen. P.G.T. Beauregard.

Breeding lines and cultivars of sweet potato, Ipomoea batatas (L.) Lam were evaluated in the field during a 4 year period for resistance to the sweet potato weevil, Cylas formicarius elegantulus (Summers). Appreciable resistance occurred in lines from Louisiana, Nigeria, Asia, and the U.S. Vegetable Laboratory. Lines performed similarly with respect to resistance when evaluated in 2 or more years.

L 86-33 sweetpotato [Ipomoea batatas (L.) Lam.] was developed by the Louisiana Agricultural Experiment Station. This breeding line has a unique combination of disease resistance and high yield and excellent baking and processing qualities.
