Study of biological diversity and cultivation features of the causative agent of barley net blotch Pyrenophora teres f. teres Drechsler in the Republic of Belarus

Abstract

As a result of the examination, the widespread distribution of Pyrenophora teres f. teres Drechsler in crops of spring barley. A collection of pure cultures was collected in the amount of 62 strains that differ in morphological characteristics of the colonies and growth rate. The most common strains belonging to the D2 and E2 groups were identified, characterized by high dense white mycelium and dense felt mycelium with an olive shade with an average growth rate. The article also presents the results of studies on the cultivation of the pathogen (temperature and light conditions), the selection of a suitable nutrient medium to obtain maximum sporulation. The racial composition of the pathogen is determined. It has been established that in our country there are races 000, 100 and 500.
