A study is 18 sorts and hybrids of melon in multidimensional space after 13 signs in a pellicle hothouse on the sun heating enabled to classify them on six clusters. Sorts part on near between itself groups. Consequently, all variety of sorts and hybrids of melon in a pellicle hothouse on the sun heating is presented by six most typical representatives. These are five sorts – Bukharka (takes place from Russia), Gull (created in Institute of vegetable-growing and bashtannictva), Fortune, Ol'viya, Goprinka (Institute of the Sonth vegetable-growing and bashtannictva, and presently the Sonth state experimental station of Institute of water problems and land-reclamation) and one hybrid is Imperial of F1 (takes place from Netherlands). Researches conducted in 2008-2010 at the Kievan experimental station of Institute of vegetable-growing and bashtannictva.
Key words: melon, greenhouses, solar heating, hybrid, variety, cluster Euclidean distance.
