Differentiation of molecular genotypes and virulence phenotypes of Puccinia triticina from common wheat in North America.

Phytopathology - 1 Jun 2009

Ordoñez M E, Kolmer J A

Abstract excerpt

Wheat leaf rust caused by Puccinia triticina is widely distributed in the wheat growing regions of the United States and Canada, and is subject to selection for virulence phenotype by leaf rust resistance genes in wheat cultivars. The objective of this study was to determine the number of genetically differentiated groups of P. triticina that are currently present in North America. In total, 148 isolates of P....
