The dwarfing trait is of considerable agronomic importance, as it enables increased planting density and reduced management costs. In melon (Cucumis melo L.), a high-value cucurbit crop, semi-dwarf plant architecture is particularly beneficial for lowering labor requirements in greenhouse trellis cultivation. In this study, a stably inherited dwarf mutant was identified from an ethyl methanesulfonate (EMS)-mutagenized population of thin-skinned inbred line ssp. agrestis ‘13C’. Using bulked segregant analysis sequencing in combination with MutMap and molecular marker validation, a key missense mutation in the CmTUB8 gene was identified, which completely co-segregates with the dwarf phenotype.
