The impact of climate change on the asexual part of population of Blumeria graminis tritici in Vojvodina region (Serbia)

Abstract

Powdery mildew is a regular and economically important disease of wheat in Serbia. The asexual part of population Blumeria graminis f. sp. tritici consists of patothypes formed by asexual reproduction during spring. The differential set of varieties and lines with resistance genes were sown in the plastic pots. At the one-leaf stage they were taken out into the field of wheat. After 48 hours the plants were getting back into the chambers with optimum conditions for plants and pathogen development. The sowing time of mobile nurseries, taking out into the field and getting back in the chambers and also the scoring were almost identical for all years. The screening of the virulence of the B. graminis f. sp. tritici population was done from the middle of March till the end of May.
