Interpretive Summary:

Technical Abstract: Three insect susceptible check cultivars (‘Beauregard’, ‘Hernandez’, and ‘SC1149 19’), three insect resistant check cultivars (‘Charleston Scarlet’, ‘Regal’, and ‘Ruddy’), and 30 advanced sweetpotato genotypes were evaluated for insect resistance in replicated field trials at Charleston, SC, in 2011. Twenty-eight genotypes had significantly less overall insect injury (i.e., higher percentage of undamaged roots) and significantly lower WDS indices than did the three susceptible checks (‘Beauregard’, ‘Hernandez’, and ‘SC1149-19’). All but nine genotypes had significantly less injury by flea beetles than did ‘SC1149-19’. Sweetpotato weevils were at very low levels in 2011.
