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.
Highlights
Pratylenchus thornei Sher & Allen, 1953 is the most economically important lesion nematode species on wheat and barley that reduces grain yield and quality (Fanning et al, 2020)
The main objective of this study is investigating the reproductive fitness of five P. thornei populations on carrot discs and wheat and barley varieties which collected from wheat and barley fields in Isparta Province in Turkey
No male was found in all P. thornei populations on carrot discs in the study
Summary
Pratylenchus thornei Sher & Allen, 1953 is the most economically important lesion nematode species on wheat and barley that reduces grain yield and quality (Fanning et al, 2020). It has been reported that the reproduction rates of these nematodes vary on wheat and barley varieties (Sheedy et al, 2007, 2008; Thompson et al, 2008; Smiley, 2009). It is stated that the susceptibility of wheat to root lesion nematodes was higher than barley (Smiley et al, 2004; Vanstone et al, 2008; Smiley and Machado, 2009). Root lesion nematodes were surveyed and identified on wheat cultivation areas in different regions of Turkey (Kasapoğlu et al, 2014; Kasapoğlu-Uludamar et al, 2018; Yavuzaslanoğlu et al, 2012, 2020). Pratylenchus thornei and P. neglectus were reported to have been found together generally at different population densities in wheat fields in Turkey (İmren et al, 2015). Göze Özdemir (2020) reported that P. thornei was the dominant species on cereal areas in Isparta and Burdur Provinces in Turkey and especially it had wide distribution on barley cultivation
