Özet
Bu çalışma, Batı Karadeniz Bölgesi Düzce ili ekolojik koşulları altında 19 adet ekmeklik buğday çeşidinin doğal enfeksiyon koşullarında yaprak hastalıklarına karşı reaksiyonlarının belirlenmesi amacıyla yürütülmüştür. Deneme tesadüf blokları deneme desenine uygun olarak 4 tekerrürlü olarak kurulmuş ve ekim işlemi 17.11.2015 tarihinde yapılmıştır. Hastalık gözlemleri ile ilgili çalışmalar; Septoria tritici etmeninin neden olduğu septorya yaprak lekesi hastalığı için süt olum dönemi başlangıcında, Puccinia striiformis etmeninin neden olduğu Sarı Pas hastalığı için çiçeklenme dönemi sonunda, Puccinia recondita etmeninin neden olduğu Kahverengi Pas için süt olum dönemi başlangıcında yapılmıştır. Tarla koşullarında doğal bulaşıklığa göre yapılan değerlendirme sonucunda hastalık oranları belirlenmiştir. Belirlenen hastalık şiddetine göre, septorya yaprak lekesi hastalığına karşı en hassas çeşidin % 60 hastalık şiddeti ile "Bereket", en tolerant çeşidin ise %14 ile "Aslı" olduğu, Sarı Pas hastalığına karşı en hassas çeşidin %45,4 ile "Tekirdağ", en tolerant çeşidin %0,6 ile "Midas" olduğu ve Kahverengi Pas hastalığına karşı ise en hassas çeşidin %22 ile "Tahirova" en tolerant çeşidin ise %0,2 ile "Midas" olduğu belirlenmiştir. Çalışma sonucunda elde edilen verilere göre septorya yaprak lekesi hastalığına karşı Aldane, Aslı, Konya 2002, Köprü, Masaccio ve Tosunbey, Sarı Pas hastalığına karşı Aslı, Esperia, Kate A1, Karasunya Odeska, Masaccio ve Midas, Kahverengi Pas hastalığına karşı ise Aldane, Aslı, Bereket, Köprü, Masaccio, Midas ve Tekirdağ çeşitlerinin ileride yapılacak ıslah çalışmaları için ümitvar olduğu görülmüştür.
This study was conducted to determine the response of 19 bread wheat varieties to natural infection of leaf diseases under ecological conditions of Düzce in the Western Black Sea Region. The trial was established in accordance with randomized block with four replications and the seeds were planted on 17.11.2015. The wheat varities were observed for the associated diseases including septoria leaf spot disease (caused by Septoria tritici during milking stage), yellow rust disease (caused by Puccinia striiformis at the end of the flowering period), brown rust disease (caused by Puccinia recondita at the beginning of milking stage). The disease severity were assessed in the field conditions according to natural contamination. According to determined diseases severity, the most sensitive variety against septoria leaf spot disease was “Bereket” with 60%, while the most tolerant variety was “Aslı” with 14%. The most sensitive variety against yellow rust disease was “Tekirdağ” with 45.4%, while the most tolerant variety was “Midas” with 0.6%. The most sensitive variety against brown rust disease was “Tahirova” with 22%, while the most tolerant variety was “Midas” with 0.2%. The results indicated that promising wheat varieties for future breeding studies were: Aldane, Aslı, Konya 2002, Köprü, Masaccio and Tosunbey (against septoria leaf spot disease), Aslı, Esperia, Kate A1, Karasunya Odeska, Masaccio and Midas (against yellow rust disease), Aldane, Aslı, Bereket, Köprü, Masaccio, Midas and Tekirdağ (against brown rust disease).
