ASSESSMENT OF RESISTANCE TO TULIP BREAKING VIRUS (TBV) IN THE TULIP COLLECTIONS OF THE BOTANICAL GARDEN OF VILNIUS UNIVERSITY

The tulip (Tulipa L.) is placed in the Liliaceae Juss. family.
The major center of origin is situated in Central Asia.
Tulips in Lithuania have been known, grown and was favourite flower for a long time.
Comprehensive knowledge of ornamental bulb plants appeared at the end of the 18^th century.
In this study, the assessment of viral diseases of 263 tulip species and cultivars grown in the Botanical Gardens of Vilnius University was carried out.
Basing on the research data obtained in the years of 1997-2010. Infected by viral diseases were selected basing on visual inspection of tulips for symptoms (Navalinskienė, Samuitienė, 2006). Identification of agents was carried out at Plant Virus Laboratory of Institute of Botany applying methods of test-plants, electron microscopy, DAS-ELISA. By resistance to Tulip breaking virus, tulip cultivars were arranged into 4 groups: 1) resistant; 2) moderately resistant; 3) non-resistant; 4) excessively non-resistant.
In the study, the collection was analyzed according to classification groups.
Triumph tulips and Single late tulips dominate.
Among the investigated 15 classification groups of tulips grown in the collection of the Botanical Gardens of Vilnius University, Darwin hybrid tulips, Kaufmanniana, Fosteriana, Greigii, varieties and hybrids and other tulip species and their varieties and hybrids are the most resistant to Tulip breaking virus.
Most cultivars of the Double early tulips and Parrot tulips were moderately resistant to Tulip breaking virus. Single early tulips, Triumph tulips, Single late tulips, Lily-flowered tulips and Fringed tulips were rather susceptible to viral diseases.
