Identification of Races 1, 2, 4 and 8 of Fusarium oxysporum f. sp. dianthi in Turkey by Using Molecular Markers

Horticultural Studies, vol.39, no.1, pp.22-27, 2022 (Peer-Reviewed Journal)

Fusarium oxysporum f.sp. dianthi (Prill and Delacr.) (Fod) is a causal agent of

wilt disease of carnation (Dianthus caryophyflus L.) with its different

physiological races. Although eleven physiological races of Fod have been

reported in the world, a polymerase chain reaction (PCR)-based diagnostic

tool was developed for identification of Fod races 1, 2, 4, and 8, which are the

most commonly found in many countries. On the other hand, there is no

information about which races are found in Turkey. A total of 91 isolates were

collected from plants with Fusarium-like symptoms in the most grown

carnation areas in Antalya, İzmir, Isparta and Yalova provinces and all isolates

were identified using molecular methods. As a conclusion, the results showed

that Fod isolates collected from the most carnation grown provinces of Turkey

consist mostly of race 1, 2 and 8. This is the first study reporting Fod races

causing wilt disease on carnation plants in Turkey.
