Özet

Carrot (Daucus carota var. sativus) is widely planted in the Ankara provinces. In order to identify species of Alternaria causing disease on root and foliage, surveys of carrot production areas in Ayas and Beypazari districts of Ankara province between June and November in 2008-2009 were undertaken. Sixty isolates of Alternaria spp. have been obtained from necrotic lesions on the leaves and roots. Alternaria radicina, A. alternata, A.tenuissima and A.dauci were isolated from symptomatic plants collected in our survey and the pathogenicity of fungi have been tested. Species identification was done based on culture and conidial morphology, growth rate and rDNA sequences. Pathogenicity test such as hypocotly test, carrot disc method, 6-8 weekly seedling and plant test were conducted Isolates of A.radicina, A.dauci were shown high virulence although Alternaria alternata were found as moderately or low virulence.
