Prospects for the use of apple tree species from the collection of the GBS RAS in landscaping

Wild apple tree species are promising for use as ornamental plants in urban and private landscaping due to the abundance of flowering, a long growing season, attractive fruiting, as well as resistance to diseases and pests. The research was carried out in the laboratory of cultivated plants of the MBG RAS from 2011 to 2022. An assessment of economically valuable traits and a morphological description of 20 apple tree species that entered the collection from 1958 to 1961 were carried out. According to the results of the study, the most promising types of apple trees for use in urban conditions were identified: Malus baccata, M. neidzwedzkyana, M. x zumi, M. sargentii, M. mandshurica by a set of parameters. The types of apple trees that, according to some of the parameters, are promising for urban gardening in Moscow: M. ioensis (low frost resistance), M. fusca, M. sievesii (scab infestation).
