ABSTRACT The genetic relationships between isolates of Puccinia triticina virulent on wheat with the Lr26 resistance gene were studied. The diversity within and between isolates of P. triticina from Israel, Europe, and the United States was determined by virulence on near-isogenic Thatcher lines and by random amplified polymorphic DNA. According to the molecular markers, isolates that were viru...
A total of 43 isolates of the wheat leaf rust fungus, Puccinia triticina Eriks, collected from Ethiopia and Germany were analysed for their genetic diversity using the amplified fragment length polymorphism (AFLP) technique. Out of 18 EcoRI/MseI primer combinations screened, 15 produced 219 highly polymorphic fragments. The average AFLP difference between pairs of the leaf rust isolates (26 fro...
The main growing regions for winter wheat in the Russian Federation are North Caucasian, Central Black Earth, and agroecological regions. Spring crops dominate Urals, Volga region, Western Siberia. Wheat leaf rust, caused by Puccinia triticina, is an important disease, impacting greatly on production. In Russia, disease was annual problem until 2010 but has since been more effectively controlle...
