Özet

The occurrence of fungal pathogens was surveyed in Jerusalem artichoke fields in Ankara province, Turkey during 2011-2012 years. A total of 106 isolates were collected from diseased plant samples. Isolates were identified as Sclerotinia sclerotiorum, S. minor, Macrophomina phaseolina, Golovinomyces cichoracearum, Fusarium oxysporum and F. equiseti. Morphological identification was confirmed by DNA sequencing and species-specific PCR assay. Sclerotinia wilt/rot disease caused by S. minor and S. sclerotiorum was the most common disease limiting Jerusalem artichoke production of Turkey. To our knowledge, S. minor, M. phaseolina, G. cichoracearum have been detected in Jerusalem artichoke fields in Turkey for the first time. Isolates of S. minor and S. sclerotiorum were also characterized for their aggressiveness and mycelial compatibility groups (MCGs). In pathogenicity test, S. sclerotiorum was observed to be more pathogenic than S. minor in this crop. 29 S. sclerotiorum isolates were classified into 16 MCGs while 64 S. minor isolates grouped into 7 MCGs. This study is the first comprehensive study on the characterization of fungal pathogens associated with Jerusalem artichoke in Turkey. (C) 2015 Friends Science Publishers
