¹ concentration of conidia ×10⁶. Mycelial fragments present in the suspension that were not counted; ² Aggressiveness: Mean of diseased germinating wheat seeds across five readings (2–6 days after starting the test) and across four dilution rates (original, 1:1, 1:2 and 1:4) related to the non-inoculated controls in two lines with differing germling resistance, M* mycelium occurred.
