Abstract

Protein and dry matter contents were determined for 16 cultivars of sweet potatoes (Ipomoea batatas (L.) Lam.) planted May 28 and harvested on 4 different dates. Means of protein contents of cultivars differed significantly and ranged from 4.17% to 6.51%, dry basis. Protein content decreased at the rate of 0.0067% per day and dry matter decreased at the rate of 23% per day.

Abstract

Protein content of sweetpotatoes from a North Carolina root collection was determined. Protein content ranged from 1.73% dry basis to 9.14%. The amino acid composition of protein extracted from 6 selected cultivars was determined. Tryptophan and total sulfur amino acids were limiting by comparison with the FAO reference protein. Other essential amino acids were in excess suggesting that sweetpotato protein may be useful in supplementing other plant proteins.

Abstract

‘Carolina Nugget’ (Fig. 1) is a moist sweet potato developed at N.C. State Univ. in 1954. In 1957 and 1958, it was tested throughout North Carolina in regional tests as the experimental clone NC 172. Although it never has been released officially as a cultivar, it has been grown for commercial use in several southern states under many different names (e.g., Red Nugget, Carolina Nugget, Golden Nugget). The formal release and naming of this sweet potato cultivar should alleviate the confusion that has occurred when growers market or buy plant material.
