Plant and fruit characteristics of the parents and progeny from the interspecific cross Cucumis melo L. (PI 140471) × C. metuliferus E. Mey. (PI 292190) are described. An electron microscope scan (EMS) indicated that F1 seed exhibited both the netting from C. metuliferus and the ridging from C. melo but pollen from both parents and the F1 appeared to be identical. The F1 plants had lobed leaves as in the staminate parent (C. metuliferus). Trichomes of the F1 were intermediate. The F1 consisted of light green fruit with raised dark green areas and dark green fruit. Thirteen plants with spiney fruit were found in the F2. Ribbing and netting of fruit and andromonoecious flower types occurred in F2 progeny but did not occur in either parent. Weight, flesh and rind thickness, length, and diameter of F1 and F2 fruit greatly exceeded those of either PI 140471 or C. metuliferus. Attempts to duplicate the original cross were unsuccessful due to embryo abortion except for one plant grown by embryo culture. Backcrosses of the F1 to C. metuliferus were unsuccessful in the greenhouse and field due to embryo abortion except for 1 plant produced by embryo culture.
