Virulence of Icelandic Pyrenophora teres f. teres populations and resistance of Icelandic spring barley lines
Abstract The causal agent of the barley net blotch disease, Pyrenophora teres , is known for its high level of diversity due to sexual reproduction. Different pathotypes, defined by a virulence combination, even within the same fields are frequently found and virulence between locations can vary con...
