Abstract :In the study, five populations of Pratylenchus thornei which obtained from different locations in Isparta Province in Turkey were investigated for their reproductive fitness on carrot discs and wheat varieties of Ikizce and Altay and barley varieties of Tarm92 and Burakbey. Reproductive fitness evaluated as the ratio of the final number of nematodes to the number of nematodes inoculated. There was a significant difference in reproductive fitness among the five P. thornei populations on carrot discs. The highest reproductive fitness on carrot discs was obtained with the P. thornei populations of SK11 and SK24 whereas pathogenicity of these populations was differentiated among wheat and barley varieties. The highest reproductive fitness was found at SK11 population with all wheat and barley varieties. GD18 and ISP10 populations developed better in barley than in wheat varieties. This study showed that there might be differences in reproduction of populations of the same nematode species isolated from different geographical areas.Keywords : Pratylenchus thornei, Reproductive fitness, Pathogenicity, Monoxenic culture
