Narrative
Leaves cordate to triangle in shape with no to slight lateral lobes, green with some protruding of abaxial veins in immature leaves. Vines and petioles green with light purple at the apex of the petiole and at the leaf axil. Newly emerging terminal leaves range from slightly to mostly purple. Plants produce a spreading vine, and form storage roots of an open-cluster type, with individual roots being elliptic to round-elliptic in shape. Skin color of roots red to purple-red which lightens during storage. Flesh color uniform dark orange flesh color. Plants produce adequate flowers and set seed readily. Flowers rounded, white limb with a purple throat, 4.4 cm in length and 3.5 in width. Outer two sepals at the base of the flower shorter than the inner sepals. Sepal shape ranges from elliptic to obovate, with the apex of the outer sepals being acute in shape and the inner sepals being obtuse; pubescence is absent and they are green in color. Slightly exerted stigma is white, and style white at the base and purple at apex. Skin of storge roots smooth, but in wet growing conditions water blisters around the root lenticels are formed. Storage root dry matter averages 19.9% compared with 18.2% and 22.5% for Beauregard and Jewel, respectively. Yield and grade consistently compared favorably with Beauregard and was superior to Jewel. Yield similar to Beauregard for the U.S.#1 and canner grades and slightly higher for jumbo grades. Harvest dates typicalloy 3-5 d earlier than Beauregard. Roots store well without excessive weight loss from storage rots or dehydration. Baked roots have uniform color, a moist smooth flesh, and good taste. Moderately resistant to soil rot (Streptomyces ipomoeae). Susceptible to southern root-knot nematode (Meloidogyne incognita). Moderate resistance to the sweetpotato flea beetle (Chaetoncnema confinis). Susceptible to white grub species (Plectris aliena) and wireworm (Diabrotica, Systena comples).
