Resumo

The prevalence of viruses in honeysuckle plants depends on the location of the plantation and the variety composition. TBRV virus had the maximal prevalence (28–60%) in most blue-berried honeysuckle stands. Prevalence of the ArMV virus ranged from 0 to 26%, that of the RpRSV virus ranged from 6 to 17%, and that of the SLRSV virus ranged from 7 to 25%. Most varieties of honeysuckle (67%) were infected with a complex of viruses, whereas no viruses were detected in certain varieties. The varieties produced at the Lisavenko Research Institute for Selection and Seedage had a higher degree of viral infection than those produced at the All-Russia Vavilov Research Institute of Plant Breeding. The viruses found in blue-berried honeysuckle plants were mostly in the latent form, but green leaf mottle and interstitial chlorosis were observed on individual bushes from a number of varieties. A tendency for virus infection accumulation with the extension of plant life was observed. TBRV and SLRSV transmission through seeds was registered, which is indicative of the need for improvement of the hybrid forms involved in the breeding process. The duration of dry air thermotherapy of honeysuckle plants should not exceed 30–45 days. Combined use of thermotherapy and meristem culture provided for an 80% yield of healthy plants.
