Fluctuation of the most frequent pathotypes in theBlumeria茎f. sp.hordeipopulation in two regions of Kazakhstan. Frequency was calculated from the total number of collected and analyzed (for pathotypes) isolates ofB. graminisf. sp.hordeiin the populations (Tables3). Frequency of pathotype 24 occurrence reliably differes from the same of other pathotypes (significant difference fromP < 0.004to<0.0001). Significant difference in occurrence frequency was not observed between other pathotypes (Р > 0,05) in the surveyed regions. Statistical analysis was performed using two-way ANOVA followed by Tukey’s multiple comparisons test.Pvalues <0.05 were considered significant
