Abstract Leaf rust is a common and costly wheat disease. The introduction of resistance genes derived from wild relatives one way to improve disease control. However, due the rapid development virulence in casual pathogen Puccinia triticina , long-term effectiveness some leaf ( Lr ) questionable. To assess this, we examined 130 accessions 13 relative species Aegilops genus. presence 9 was deter...

Due to the global warming and dynamic changes in pathogenic virulence, leaf rust caused by Puccinia triticina has greatly expanded its epidermic region become a severe threat wheat production. Genetic bases of resistance mainly rely on (Lr) gene or quantitative trait locus (QLr). Although these genetic loci have been insensitively studied during last two decades, an updated overview Lr/QLr geno...

In the Rostov region, among cereal crops, winter wheat occupies a leading position in terms of sown area. Breeders have developed varieties, productivity potential which is 1.5–2 times higher than their actual yield production. One most important factors that can destabilize gross grain harvests and reduce are parasitic organisms, dangerous rust pathogens ( Puccinia triticina, P.striiformis, P....
