Study of Genetic Variation of Common Ash (Fraxinus Excelsior L.) Affected by the Ash Dieback in the Czech Republic
Original language description
Ash dieback is a pandemic disease of common ash (Fraxinus excelsior L.) which has become widespread in Europe since it was first time recorded in Poland in the mid of 1990s. Its causing agent, fungus Hymenoschyphus fraxineus, is an invasive alien species introduced to Europe from East Asia. Zhao et al. (2012), Gross et al. (2014). The fungus causes huge damage to ash populations and represents severe threat for the decline of the species and considerable reduction of its population density. In the intensity of dieback, considerable intraspecific (genetic) variation was observed in common ash (McKinney et al. 2011, Kjaer 2012, Stener 2013). Strong genetic control of the susceptibility and resistance of ash to the infection by H. fraxineus was proved by Lobo et al. (2015). Infection-tolerant trees represent only a small fraction (1-5%) of ash populations in Sweden, Denmark and Lithuania, however. The goal of our study is the assessment of current and expected levels of genetic variation of common ash due to the ash dieback by means of the combination of DNA microsatellite markers and study of phenotypic traits of the species.
