The Melon Genome: Designing for NextGen Agriculture, CRC, Ghent, Belgium , ss.11-36, 2026
Melon (Cucumis melo L.) shows a wide diversity in its seedlings, leaves, inflorescences, and even more so in its fruits in terms of shape, size, rind color, dots and patches on the skin, warts, grooves, shape of the base and apex, size of pistil scar, cork formation/netting, flesh color, thickness, sweetness and firmness, seed cavity, seed size, and seed color characteristics. Horticultural groups and subgroups have been created according to these features. Because melon has a long and confusing taxonomic history, this chapter discusses melon accessions that have been cultivated and collected in the wild from various parts of the world and preserved in gene banks. Three continents have been proposed as the center of origin of the melon, respectively: Africa, Asia, and Australia/Oceania/New Guinea. Using a variety of descriptors, morphological characterization was performed, followed by later genetic characterization using molecular markers and biochemical characterization of various melon groups. This chapter addresses biodiversity, classification, botanical groups, domestication, and morphological and molecular diversity studies of melon.
