The collection of the genus Pelargonium L'Herit.ex Ait is studied and preserved in FRC SSC RAS. It consists of diverse species and hybrids, as well as highly decorative cultivars of pelargoniums. (angels, zonal, ivy-leaved, unique and largeflowered). In order to expand the genetic diversity of pelargoniums for breeding research, as well as to replenish the assortment of flower crops, new species are being searched. The objects of research were 4 rare species of the Pelargonium section. Pelargoniums that underwent introduction tests in 2016–2020 successfully completed the full cycle of development, including fruiting. The seeds ripened in August-September, and their germination ranged from 45 % to 75 %. P. cucullatum subsp. tabulare and P. cucullatum subsp. strigifulium showed resistance to diseases and pests, while P. citronellum and P. cucullatum subsp. cucullatum were damaged by Trialeurodes vaporariorum. Flowering and formation of fruit and fullfledged seeds indicate a high adaptive potential of these species. The maximum introduction score of 24 points was obtained by subspecies P. cucullaium subsp. tabulare and P. cucullatum subsp. strigifulium. They are recommended for inclusion in the breeding process as sources of adaptability.
