Popis: The results of breeding of the Ussuri pear (Pyrus ussuriensis Maxim.), in the arboretum of the M.F. Reshetnev Siberian State University of Science and Technology, located in the green zone of the city of Krasnoyarsk in the territory of the educational and experimental forestry, are presented. Ussuri pear trees were selected by biometric parameters and fruiting. The mother specimens that reach the maximum (8.6 m – A685-15) and minimum (5.4 m – A685-5) height were highlighted. Stem diameter varies from 8.0 to 18.0 cm. According to the results of observations for the studied years, the plants with the largest number of fruits (A685-8, A685-13) and the smallest number of fruits (A685- 19) were selected. To replenish the collection of the arboretum, seed offspring were grown, among which the best specimens were revealed. Individuals that have an advantage in height (A685-20) and stem diameter (A685-11) at the early stages of ontogenesis were identified. This allows you to select specimens according to the studied characteristics.
