Background. Information on the races of Puccinia triticina Erikss. in Novosibirsk Province is needed to identify sources of effective genes for leaf rust resistance. The goal hereof was monitoring genetic variability of the P. triticina population in the

Physiologic Specialization of Puccinia triticina in Canada in 1998 [PDF]
In 1998, leaf rust of wheat (Triticum aestivum), caused by Puccinia triticina, was widespread throughout the prairies of western Canada. Warm summer temperatures with frequent dew periods favored spread of the disease in wheat fields in Manitoba and Saskatchewan.

Virulence of Puccinia triticina on Wheat in the United States in 1999 [PDF]
Isolates of Puccinia triticina were obtained from wheat leaf collections made by cooperators throughout the United States and from surveys of wheat fields and nurseries in the Great Plains, Ohio Valley, and Gulf Coast states in 1999. Pathogenic races were determined from virulence/avirulence phenotypes on 14 host lines that are near-isogenic for leaf ...

Physiologic Specialization ofPuccinia triticinain Canada in 1997 [PDF]
In 1997, leaf rust of wheat (Triticum aestivum), caused by Puccinia triticina, was widespread throughout the prairies of western Canada. Warm summer temperatures with frequent dew periods favored spread of the disease in wheat fields in Manitoba, Saskatchewan, and Alberta.

Genetic Variation and Virulence on Lr26 in Puccinia triticina [PDF]
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.

Phytopathological screening of common winter wheat lines for resistance to Puccinia triticina
. Leaf rust on wheat caused by P. triticina is the most widespread fungal disease worldwide and in Bulgaria. The development of wheat genotypes resistant to leaf rust is related to the different types of resistance and ways of gene inheritance.
