Abstract
Sex, as a factor affecting recombination during meiosis, was investigated in Cucumis melo L. A pair of backcrosses, using an F1 male parent (BCM) and an F1 female parent (BCF) was generated. The two populations were mapped at 34 loci. Total map lengths in the respective populations were nearly indistinguishable, whereas 4 marker intervals, parts of the linkage groups in the map, were significantly different between BCM and BCF.
