Bingöl and Isparta are two remote regions with significant differences in terms of apple production in Turkey. In this study, some morphological and physiological characteristics of the apple scab (Venturia inaequalis) were measured and compared between these two regions. Colony colors and boundary lines, mycelial structures, colony growth rates, conidial numbers and sizes of the isolates were measured and compared in controlled conditions. With respect to colony morphologies of Bingöl and Isparta isolates, important differences were observed. On the other hand, coloni development rate of Bingöl isolates in PDA, MEA and CMA media were statistically significant, exhibiting an average of 30% faster growth compared to Isparta isolates. In addition, conidial numbers in 1 cm² area of PDA were to be higher and significant in Bingöl isolates. However, it has not been determined differences for the dimensions of the conidial isolates developed in PDA belonging to two districts. As a result, it is considered that the morphological and physiological privileges determined by the comparison of the two district isolates of apple black spot is important. These results may be due to the genetic or fungicidal pressure due to the new race formation and the phenotypic characteristics due to different agricultural applications.
