Use of seedlings for predicting field resistance of wheat toErysiphe graminis f. sp.tritici

Article

Abstract

Seedlings can be used to predict field resistance, if any, of wheat varieties and experimental lines to wheat powdery mildew fungus,Erysiphe graminis f. sp.tritici. First leaves of 8-day-old seedlings of a field-resistant wheat showed a greater frequency of primary infections in subsidiary cells of stomata than those in a susceptible wheat. This method of predicting field resistance of experimental lines from seedling studies should prove time-saving because crosses involving field-resistant experimental lines can be made in the same generation.

Užití klíčních rostlin pro indikaci polní resistence pšenice k padlí travnímu

Abstract

Klíčních rostlin lze použít pro předpovídání polní odolnosti odrůd a experimentálních linií pšenice vůči padlí travnímu,Erisyphe graminis f. sp.tritici. U prvních listů osmidenních klíčních rostlin odrůdy v polních podmínkách odolné bylo více primárních infekcí ve vedlejších buňkách průduchů, než u odrůdy náchylné k infekci.
