Wheat stem rust caused negligible yield losses in 1997 and 1998. Overwintering sites were found in central and east-central Louisiana in 1997, and in northwestern Florida, northeastern Louisiana, and central Texas in 1998. Race Pgt-TPMK predominated in 1997 with 69% of 100 isolates with race RCRS next at 11%. In 1998, race RCRS predominated with 55% of 132 isolates, and TPMK occurred at 10%. Race QFCS occurred at 8% in 1997 and 31% in 1998. Races QCCS and QTHJ were found in 1997, and races QFBS… Expand

Wheat leaf and stem rust in the United States
TLDR
The low levels of stem rust infections in the US can be attributed to the increasing use of highly resistant winter and spring wheat cultivars, which has greatly reduced the overall level of stem Rust urediniospores. Expand
Detection of Ug99 (TTKSK) of wheat stem rust fungus and new virulence races of Puccinia graminis f.sp. tritici in Egypt
TLDR
The obtained results would serve as a fruitful tool in wheat breeding program directed for disease resistance in field conditions under field conditions and on monogenic Sr's lines against stem rust disease in both seasons. Expand
Genome-wide association study of stem rust resistance in a world collection of cultivated barley
TLDR
QTL conferring a 14–40% reduction in adult plant stem rust severity to multiple races of Pgt were found on chromosome 5H and will be useful in barley breeding and suggests that it may be effective against other races in the Ug99 lineage. Expand
Identification of pathotypes of the sorghum rust pathogen, Puccinia purpurea, in Australia
TLDR
Evidence is provided that pathotypes of P. purpurea exist in the sorghum growing regions of Australia and has resulted in the development of a protocol for identifying pathotypes and screening breeding and experimental lines for resistance to these pathotypes. Expand
Vulnerability of Barley to African Pathotypes of Puccinia graminis f. sp. tritici and Sources of Resistance.
TLDR
The main objectives of this study were to assess the vulnerability of barley to pathotype TTKSK and identify possible sources of resistance, and to combine rpg4/Rpg5 with resistance genes from these other sources to provide more durable resistance against the array of different virulence types in the Ug99 race group. Expand
Control of fungal diseases in winter wheat
The relationships between plant diseases, winter wheat characteristics, air temperature and precipitation, site factors and agricultural practices were investigated. Regression analyses revealed thatExpand
Comparing infection and colonisation of Puccinia graminis in barley and wheat
TLDR
The period between 120 and 240 hpi may hold some explanation for the perceived lower stem rust receptivity in barley, since a steep increase in accumulated fungal biomass observed in the susceptible wheat Line 37 − 07 was not seen in the vulnerable barley entries at the same time interval. Expand
Genetic Mapping of Loci for Resistance to Stem Rust in a Tetraploid Wheat Collection
TLDR
To identify quantitative trait loci conferring resistance to stem rust at the seedling stage, an association mapping panel consisting of 230 tetraploid wheat accessions were evaluated for reaction to five Pgt races under greenhouse conditions, allowing for genome-wide association mapping of resistance QTLs in wild, landrace, and cultivated tetraPloid wheats. Expand
Microsatellite Markers Linked to Stem Rust Resistance Allele Sr9a in Wheat
TLDR
Results suggest that Xgwm47 will be a useful tool for marker-assisted selection of Sr9a in wheat breeding programs, and despite the ambiguity of phenotypic evaluation, X gwm47 was diagnostic for Sr 9a in additional NILs tested. Expand
Diagnostic microsatellite markers for the detection of stem rust resistance gene Sr36 in diverse genetic backgrounds of wheat
TLDR
These codominant markers were easy to score and diagnostic for Sr36 in a set of 76 wheat cultivars and breeding lines developed in 12 countries and can be used in marker-assisted selection of Sr36. Expand
