Thirteen independent linkage groups have been described until now in muskmelon but no relation has been identified between a linkage group and a chromosome.

 

Group 1:	si-1 (short internode-1) - yv (yellow virescence).
Group 2:	Vat (Virus aphid transmission resistance) - Pm-w (A gene for powdery mildew resistance in WMR 29, allelism tests have not been made with the 6 described powdery mildew resistance genes) - Fn (Flaccida necrosis).
Group 3:	ms-1 (male sterile-1) - r (red stem) - gl (glabrous) - Pa (Pale).
Group 4:	a (andromonoecious) - O (Oval fruit shape) - h (halo cotyledons) - Pm-x (Powdery mildew resistance in PI 414723, allelism tests have not been made with the 6 described powdery mildew genes) - Zym (Zucchini yellow mosaic virus resistance). The order in this group is unknown.
Group 5:	Prv (Papaya Ringspot virus resistance) - Fom-1 (Fusarium oxysporum f. sp. melonis resistance 1)
Group 6:	ms-2 (male sterile-2) - yg (yellow green foliage) - Fom-2 (Fusarium oxysporum f. sp. melonis resistance 2)
Group 7:	nsv (necrotic spot virus resistance) - Pm-3 (Powdery mildew resistance - 3)
Group 8:	f (flava) - lmi (long mainstem internode)
Group 9:	ms-4 (male sterile-4)
Group 10:	dl (dissected leaf)
Group 11:	v (virescent)
Group 12:	ms-3 (male sterile-3
Group 13:	ms-5 (male sterile-5)
