European Leaf Rust of Wheat Nurseries (ELRWN 1989/1990) have been composed of 20 genetically different resistant spring wheat lines and five isogenic Lr lines. This cooperative investigations are refer to interactions between genetically different sources of resistance of wheat to the wide spectrum of virulence of Puccinia recondita tritici. ELRWN have been tested in the seedling stage to different international pathogen cultures and in the adult stage on the large European-Mediterranean epidemiological territory. Cooperative seedling testings of this nursery have been realized in eight countries. The field reactions of ELRWN 1989/90 to pathogens of leaf rust, stem rust, yellow rust, powdery mildew and Septoria sp. have been evaluated in thirteen countries.
