Abstract:Four cycles of recurrent selection in a random crossing population of sweet potato. Ipomoen batatas (L..) Lam., increased incidence of resistance to root damage by the grub of Plectris aliena Chapin and the incidence and leavels of resistance to larvae of the southern potato wire-worm, Conoderus falli Lane; the banded cucumber beetle, Diabrotica balteata LeConte; the spotted cucumber beetle, D. undecimpunctata howardi Barber; the clongate flea beetle, Systena elongate (F.); and S. frontalis (F.). No appreciable improvement in resistance to the sweet-potato flea beetle, Chaetocnema confinis Crotch, was detected, but resistance to this insect was relatively high in the original population.
