Comparative Resistance of Barley and Wheat Germplasm to Common Root Rot Caused by Bipolaris sorokiniana

Abstract

This study evaluated the resistance of 54 wheat and 14 barley cultivars in Bolu, and 6 wheat cultivars and 89 barley lines in Eskişehir, to common root rot caused by Bipolaris sorokiniana under controlled conditions. Location-specific B. sorokiniana isolates (wheat-derived in Bolu, barley-derived in Eskişehir) were employed for evaluation. In Bolu, wheat cultivars demonstrated tolerance with variable disease severity, while barley cultivars showed moderate susceptibility with significantly greater disease severity than wheat. Conversely, wheat cultivars in Eskişehir exhibited complete resistance with no symptoms, whereas barley lines displayed responses ranging from complete resistance to high susceptibility. Eight wheat cultivars and two barley lines achieved complete resistance across both locations. Neither growth habit (spring vs. winter) in wheat nor row-type (two-row vs. six-row) in barley significantly influenced disease severity. The consistent difference in disease severity between barley and wheat, with barley exhibiting greater susceptibility, highlights the importance of targeted breeding efforts for each crop. Field evaluations are crucial to validate the findings under natural conditions and refine disease management strategies.

Öz

Bu çalışmada, Bolu'da 54 buğday ve 14 arpa çeşidinin, Eskişehir'de ise 6 buğday çeşidi ve 89 arpa hattının Bipolaris sorokiniana tarafından neden olunan kök ve kökboğazı çürüklüğüne karşı dayanıklılığı kontrollü koşullar altında değerlendirilmiştir. Lokasyona özgü B. sorokiniana izolatları (Bolu'da buğday kaynaklı, Eskişehir'de arpa kaynaklı) değerlendirme için kullanılmıştır. Bolu'da buğday çeşitleri değişken hastalık şiddeti ile tolerans gösterirken, arpa çeşitleri buğdaya göre önemli ölçüde daha fazla hastalık şiddeti ile orta derecede duyarlılık sergilemiştir. Eskişehir'deki buğday çeşitleri ise belirti göstermeksizin tam dayanıklılık sergilemiş, arpa hatları tam dayanıklılıktan yüksek duyarlılığa kadar değişen tepkiler göstermiştir. Sekiz buğday çeşidi ve iki arpa hattı her iki lokasyonda tam dayanıklılık göstermiştir. Buğdayda vejetatif gelişim tipi (yazlık veya kışlık) ile arpada başakta sıra tipinin (iki sıralı veya altı sıralı) hastalık şiddeti üzerinde etkisi olmamıştır. Buğday ve arpa arasında gözlemlenen belirgin hastalık tepkisi farklılığı, her iki tür için farklı ıslah stratejilerinin gerekliliğini ortaya koymaktadır. Elde edilen bulguların doğal çevre koşullarında da doğrulanması ve hastalık yönetimi stratejilerinin geliştirilmesi açısından tarla denemeleri büyük önem arz etmektedir.
