Приведены результаты изучения вредности возбудителя пыльной головни на пшенице озимой. Установлено, что у зараженных растений уменьшаются количество зерен в колосе, масса зерна с колоса, масса 1000 зерен, энергия прорастания, лабораторная всхожесть, количество продуктивных побегов, урожайность. Выявлены четыре сортообразца, устойчивые к возбудителю пыльной головни, с высокими показателями хозяйственно-ценных признаков.
Ключевые слова: Ustilago tritici (Pers.) Jens, black (volatile) smut, winter wheat, resistance, disease, cultivar, damage, harmfulness, infectious background
