COMPARATIVE ANALYSIS OF THE ACLSV, ASPV, PNRSV, PPV FREQUENCY OCCURRENCE IN THE FRUIT CROPS PLANTATIONS

Abstract

A comparative analysis of the ACLSV, ASPV, PNRSV, PPV frequency occurrence in the fruit crops plantations of RUE “Institute of Fruit-growing” for 2016–2020 period was carried out. ACLSV diagnostics (484 apple-tree samples, 129 pear samples) made it possible to establish that the virus is more common on the apple-tree (33.5 % of infected samples in the breeding garden, 37.9 % in the mother-cuttings garden, 1.6 % in the production garden), than on a pear (2.8 % of infected samples, only in the selection garden). ASPV was detected in 28.5 % of apple-tree samples (of 123 tested), apple and pear rootstocks, pear species are virus-free. PNRSV was not detected (368 tests) on domestic plum, cherry plum and apricot in collection and mother plantations. In the collection planting, the presence of the virus was confirmed on one cherry species and nine cherry species, in the mother planting the virus was not diagnosed. PPV (368 tests) was not diagnosed on all tested drupaceous fruit plants.
