Analysis of Host-Specific Differentiation of Puccinia striiformis in the South and North-West of the European Part of Russia

Yellow (stripe) rust, caused by Puccinia striiformis Westend. (Pst), is a major disease of cereals worldwide. We studied Pst virulence phenotypes on Triticum aestivum, Triticum durum, and triticale in thre...
