Determination of seed-borne fungal pathogens on harvested canola (Brassica napus L.) seeds from Thrace Region
Öz
The aim of this study was to determine fungal pathogens on seed samples of canola collected in 2013 from the fields located on Edirne, Tekirdağ, Kırklareli provinces of Thrace region, and their pathogenicity. Additionally, the cultural and morphological characteristics of fungal species, which were highly pathogenic, were determined. As a result of the study, it was found that seed samples collected from Thrace region of Turkey were contaminated with A. alternata in the alternata species groups of Alternaria genus at the highest rate, A. ethzedia and A. infectoria in the infectoria species groups of the same genus followed it. Other species detected in canola seed samples were Arthrinium arundinis, Cladosporium sp., Curvularia sp., Fusarium sp., Phomopsis sp. and the most common species of these was A. arundinis. In the result of pathogenicity tests, A. alternata isolates caused disease severity between 52.2-76% on seedling; the isolates of A. ethzedia had virulence capacity ranged from 31.5 to 82%. This range was between 24.7-70.5% for A. infectoria and between 56.20-69.20% for A. arundinis.
