Abstract

Turfgrass is frequently used today in the arrangement and aesthetic beautification of grounds in parks, gardens, median strips, recreation and sports areas. In this study, surveys were conduct in turfgrass areas in the three provinces of Türkiye. As a result of isolations from the collected samples, 44 isolates obtained belonging to five different species including and which have different virulences. Identification of the isolates were performed by rDNA-ITS sequence analyzes. According to the pathogenicity tests results, the most virulent species was M62 with a disease severity value of 91.93%. This was followed by M1584 and M63, with disease severity values of 91.12% and 91.08%, respectively. The virulence of isolates varied among the species. Only 13 of the 31 species were found to be virulent in turfgrass, was less virulent than the others in . The most virulent isolate of each species was tested on four different cereal varieties. and had low virulence values in barley and oat than the other species, while the other three species showed high virulence in turfgrass, wheat and barley, other than oat. In the phylogenetic neighboor-joining tree belonging to 44 isolates clearly demonstrated that the isolates were grouped into five distinct clusters. were considered genetically close isolates.
