Özet

In this study, researches on white-tip nematode in rice, which is important problem in rice cultivation of our country, were evaluated.
Rice white-tip nematode, Aphelenchoides besseyi, was respected quarantine pest according to Regulation on Plant Quarantine. Distribution
of A. besseyi were found among 7.80 and 43% at some location, Balıkesir, Çanakkale, Çankırı, Çorum, Edirne, Tekirdağ and Kırklareli
province in different investigations. In nematode-contaminated plots of yield losses experiments where it was seen that decreases of yield,
weight of 1000 seeds and rice output (milled rice yield) were 28.11-57.91%, 12.11-22.35% and 12.78% respectively (P<0.01). Variations
among varieties were observed for resistance against rice white-tip nematode on some researches. These findings make a promise for
breeding programs
