Kok ur nematodlari ( Meloidogyne spp.) (Nematoda: Meloidogynidae)) biberlerde onemli urun kayiplarina neden olan bir zararlidir. Bu calisma 2010-2014 yillarinda Biyolojik Mucadele Arastirma Istasyonu Mudurlugu ve Alata Bahce Kulturleri Arastirma Istasyonu Mudurlugunde yurutulmustur. Elliyedi saf biber hatti Mersin ilindeki biber alanlarindan alinan Meloidogyne incognita (Kofoid & White) Chitwood, populasyonuna karsi 25±2.0°C testlenmistir. Nematod inokulasyonundan 60 gun sonra ur skalasina bakilarak degerlendirme yapilmistir. Testlenen biber genotiplerinden 27 adeti 0-2, 30 adeti 3-5 ur skalasi grubunda yer almistir. Dayanikli bulunan hatlar, farkli M.incognita populasyonuna karsi uc kez tekrar test edilmistir. Dayanikli hatlar ile hassas olan yuksek verimli hatlar melezlenerek verim degerleri alinmistir. Bunlardan 913XH9, 100XH8, N-269X1547 ve N269X953-W melez kombinasyonlari en yuksek verim performansi gostermislerdir. Yeni cesit adaylari kok-ur nematodunun ekonomik kayiplara neden oldugu tarim bolgelerinde ticari olarak kullanilabilir.
