Lily genetic diversity evaluation in the collection of Kaunas botanical garden of Vytautas Magnus university

Research of plant diversity : present ang future : abstracts of international scientific conferenece, June 27–28, 2013, KaunasClassification type of lilies (Lilium) has been established several centuries ago. DNA technology helped to better identify individual species and to evaluate their diversity (Persson et al., 1998; Wen & Hsiao, 2001; Horning et al., 2003). About 100 species of lily family have a great genetic diversity which has been assessed in different ways. true kinds of seedlings were obtained using inbreeding or hybridization with the same species, usually such kind of plants has the same phenotype. New species which are grown traditionally are adapted to severe climatic condi­ tions. This is the source of production of healthy and resistant varieties. Worldwide genetic studies of lilies were done analyzing chinese and Korean populations using molecular techniques (Weihua et al., 2011). for a long time Lithuanian ornamental plant genetic resources and biodiversity have not been thoroughly studied, recorded and stored. Thus a lot of unique cultivars have been permanently lost. research into all kinds of evaluation and assessment has just started. selection of valuable and perspective species is required to continue and add new species. Therefore it is important to identify pre­existing varieties and hybrids using morphological features characteristic and DNA markers. Investi­ gated and adapted molecular techniques to decorative plant crops can help faster and better perform many breeding work processes. Whenever possibility to control the variability and stability between plant regeneration, it is possible to predict the variability in reproduction and plants storage in vitro. The aim of this work was to use an inter­simple sequence repeats (Issr) method in order to evaluate the genetic variability of different lily kinds in the collection of Kaunas Botanical Garden of Vytautas Magnus UniversityBiologijos katedraBotanikos sodasGamtos mokslų fakultetasVytauto Didžiojo universiteta
