Abstract. The article presents the results of a scientific expeditionary survey of the species and form diversity of wild pear in the territory of southern Kyrgyzstan. During the scientific expedition, the areas of growth of wild species and the form diversity of pears were determined, morphological features and habitats of specimens were described. As a result of the expedition, 29 specimens belonging to 5 pear species were found, as well as interspecific hybrid forms: P.communis L. - 12 accessions.; P.korshynskyi Litv. - 4 accessions; P.bucharica Litv. - 3 accessions; P. regelii Rehd - 2 accessions; P.vavilovii M.Ror. - 2 accessions. and interspecific hybrid forms - 6 accessions. The discovered accessions were attracted to the world collection of the Research Institute of Plant Genetic Resources for conservation and further comprehensive study and pomological evaluation. It should be noted that the range of wild pear and other fruit crops in nature is currently sharply reduced. The main reasons are anthropogenic activities: cutting trees for firewood, grazing, etc.
