Abstract

Progeny from a hybridization of C. melo L. (PI 140471), a feral Cucumis melo, with the nematode-resistant African horned cucumber (C. metuliferus E. Mey.) (PI 292190) were screened for resistance to Meloidogyne incognita acrita Chitwood. Although C. metuliferus exhibited resistance, no resistance was observed in PI 140471 nor in the F2 generation after inoculation with a larval suspension having 600 larvae/ml. However, when grown in contact with chopped galled roots, certain progeny appeared to be resistant. Evaluation of egg mass production revealed that the resistant plants produced significantly fewer eggs than susceptible plants.
