The Use of an Alternative Differential Set for Determination of Pyrenophora teres f. maculata Pathotypes

Pyrenophora teres f. maculata incites spot form of barley net blotch  disease. For determination of Pyrenophora teres f. maculata  pathotypes, a differential set consisted of 22 international cultivars  and genotypes and a susceptible Turkish barley variety Bulbul 89  were tested using 45 isolates obtained from different regions of  Turkey. Nineteen pathotypes were determined out of 45 isolates  used. It appears that this differential set could be useful for  determination of P. teres f. maculata pathotypes.
