Occurrence and characterization of Puccinia triticina in Zimbabwe

Canadian Journal of Plant Pathology
Wheat leaf rust caused by Puccinia triticina (Pt) is an important disease of bread wheat in Zimbabwe. This study was carried out to determine the distribution, avirulence/virulence profile(s) and genotypic variation among isolates of the pathogen. In total, 104 single-pustule isolates were established from infected wheat samples that were collected ...

Virulence and Molecular Polymorphism of Puccinia triticina Pathotypes in Egypt

International Journal of Phytopathology, 2020
Forty wheat leaf rust (Puccinia triticina) pathotypes were collected from eleven Egyptian governorates during the two growing seasons 2016/2017 and 2017/2018 were analyzed based on both virulence and molecular marker analysis. Virulence analysis was carried out on the basis of infection type of the tested pathotypes on 20 differential monogenic lines ...

Virulence of Puccinia triticina on Wheat in Nebraska during 1997 and 1998 [PDF]

Plant Disease, 2001
Urediniospore isolates of Puccinia triticina were obtained from wheat leaf collections made in three wheat-growing regions in Nebraska in 1997 and in four regions in 1998. Using 16 Thatcher lines that are near-isogenic for leaf rust resistance, 17 virulence phenotypes were found among 121 single uredinial isolates in 1997, and 42 virulence phenotypes ...
