ABSTRACT The endophyte Piriformospora indica colonizes roots of a range of host plants and increases biomass production and resistance to fungal pathogens and, thus has been considered a biocontrol fungus. However, the field performance of this fungus has not yet been tested in temperate climates. Therefore, we evaluated the performance of this fungus in(More)
The present study aimed to localize exotic quantitative trait locus (QTL) alleles for the improvement of leaf rust (P. triticina) resistance in an advanced backcross (AB) population, B22, which is derived from a cross between the winter wheat cultivar Batis (Triticum aestivum) and the synthetic wheat accession Syn022L. The latter was developed from(More)
Breeding for resistance is an efficient strategy to manage wheat leaf rust caused by Puccinia triticina f. sp. tritici. However, a prerequisite for the directed use of Lr genes in breeding and the detection of new races virulent to these Lr genes is a detailed knowledge on Lr genes present in wheat cultivars. Therefore, respective molecular markers for 18(More)
Eyespot is a major disease of common wheat (Triticum aestivum L.) in temperate climates and causes yield losses of up to 40%. The causal agents of eyespot are Oculimacula acuformis (syn. Tapesia acuformis; anamorph: Helgardia acuformis syn. Pseudocercosporella herpotrichoides var. acuformis) and O. yallundae (syn. T. yallundae; anamorph: H. yallundae syn.(More)
The range of publicly available data on plant nucleotide sequences opens a new possibility in the design of SNP assays. The purpose of this study was to identify point mutations in genomic sequences closely linked to the Lr1 leaf rust resistance gene, and to develop SNP markers based on primer extension (SNuPE) facilitating efficient marker-based selection(More)
Three rye populations originating from different cultivars were subjected to half sib progeny selection for three cycles to improve their resistance to powdery mildew (Erysiphe graminis DC. f.sp. secalis Marchal). Selection was carried out in the greenhouse (measurement of spore production at the three-leaf stage), in the field (scoring of mildew infections(More)
