Abstract: | Diseases caused in wheat by Bipolaris sorokiniana and Drechslera tritici-repentis have led to considerable yield and production losses. In wheat seeds another isolate has recently been identified, resembling Bipolaris bicolor. The objective of the present trial was to differentiate and identify isolates of these fungi based on electrophoretic analyses and morphology. Esterase electrophoresis enabled the differentiation between Drechslera sp. and Bipolaris sp. isolates. In relation to morphology, conidia from D. tritici-repentis isolates were significantly longer than the isolates of B. sorokiniana. Bipolaris bicolor isolates, on the other hand, presented wider conidia than those of D. tritici-repentis and B. sorokiniana. |
