Abstract
One of the ways to combat the penetration and spread of dangerous pathogens of fungal plant diseases on the territory of the republic may be the selection of domestic varieties resistant to fungal phytopathogens and a reduction of the import of planting material. Over the past decades, the Central Botanical Garden of the National Academy of Sciences of Belarus (CBG) has been working on the development of new cultivars of coniferous plants for landscaping purposes. The purpose of this study was to study of the composition of the mycobiota of needles and shoots of ornamental forms of Scotch pine of the CBS breeding.The article presents the results of the survey of Pinus sylvestris L. cultivars of CBG selection, carried out in the period 2020–2021 years in The Central Botanical Garden of NAS (Belarus, Minsk). As a result, it was found that among the 18 of Pinus sylvestris L. cultivars of CBG selection, the most stable were ‘Woshodjaschaia’ and ‘Minchanka’, the least stable were ‘Karolina’ and ‘Chupa Chups’.The species composition of the mycobiota of needles and shoots includes such dangerous pathogens as fungi from the genus Lophodermium, causing premature falling of needles, as well as Cyclaneusma minus, causing premature yellowing and falling of needles, and Gremmeniella abietina, the causative agent of scleroderriosis or pine shoot cancer. Among the less dangerous fungi, conditionally pathogenic species have been identified – Alternaria alternara, Auerobasidium pullulans, Cladosporium spp., Phoma spp., as well as the endophyte fungus Sydowia polyspora.
