Resistance to Aphis gossypii in Muskmelon123

Abstract

Breeding line LJ 90234 muskmelon, Cucumis melo L., was resistant to natural infestations of western biotypes of the melon aphid, Aphis gossypii Glover, in the field and to controlled infestation in the glasshouse. However, LJ 90234 was very susceptible to western flower thrips, Frankliniella occidentalis (Pergande). Muskmelons re sistant to southeastern biotypes of aphid were susceptible to the western biotype.
