DISEASES OCCURRING ON Hordeum bulbosum FIELD POPULATIONS AT BİNGÖL PROVINCE OF TURKEY

Abstract

Hordeum bulbosum is one of the wild barley species naturally growing in Bingöl province of Turkey. This wild species is an important gene source for obtaining disease resistant plants. In 2018, a survey was carried out in order to determine the diseases occurring on Hordeum bulbosum plants in Bingöl province. Twenty-seven naturally growing Hordeum bulbosum populations from Bingöl central district and Genç, Adaklı, Kiğı, Karlıova and Solhan districts were examined. Five Hordeum bulbosum populations were disease free. Powdery mildew caused by Blumeria graminis f. sp. hordei, leaf rust (brown rust) caused by Puccinia hordei, spot form of net blotch caused by Drechslera teres f. maculata and scald caused by Rhynchosporium commune were observed in other populations. Powdery mildew was the most common pathogen followed by leaf rust (brown rust), spot form of net blotch and scald.
