Genome-wide association mapping for resistance to leaf rust, stripe rust and tan spot in wheat reveals potential candidate genes
(Springer, 2018)
Leaf rust (LR), stripe rust (YR) and tan spot (TS) are some of the important foliar diseases in wheat (Triticum aestivum L.). To identify candidate resistance genes for these diseases in CIMMYT’s (International Maize and ...

Identification and validation of single nucleotide polymorphic markers linked to Ug99 stem rust resistance in spring wheat
(Public Library of Science, 2017)
Wheat stem rust (Puccinia graminis f. sp. tritici Eriks. and E. Henn.) is one of the most destructive diseases world-wide. Races belonging to Ug99 (or TTKSK) continue to cause crop losses in East Africa and threaten global ...

Genome-wide association mapping for leaf tip necrosis and pseudo-black chaff in relation to durable rust resistance in wheat
(Crop Science Society of America, 2015)
The partial rust resistance genes Lr34 and Sr2 have been used extensively in wheat (Triticum aestivum L.) improvement, as they confer exceptional durability. Interestingly, the resistance of Lr34 is associated with the ...

Genomic selection in wheat breeding using genotyping-by-sequencing
(Crop Science Society of America, 2012)
Genomic selection (GS) uses genome-wide molecular markers to predict breeding values and make selections of individuals or breeding lines prior to phenotyping. Here we show that genotyping-by-sequencing (GBS) can be used ...
Article
Optimal design of preliminary yield trials with genome-wide markers
(Crop Science Society of America (CSSA), 2014)
Previous research on genomic selection (GS) has focused on predicting unphenotyped lines. GS can also improve the accuracy of phenotyped lines at low heritability, e.g., in a preliminary yield trial (PYT). Our first objective ...

Genetic gain from phenotypic and genomic selection for quantitative resistance to stem rust of wheat
(Crop Science Society of America, 2015)
Stem rust of wheat (Triticum aestivum L.) caused by Puccinia graminis f. sp. tritici Eriks. and E. Henn. is a globally important disease that can cause severe yield loss. Breeding for quantitative stem rust resistance ...

Breeding value of primary synthetic wheat genotypes for grain yield
(Public Library of Science, 2016)
To introduce new genetic diversity into the bread wheat gene pool from its progenitor, Aegilops tauschii (Coss.) Schmalh, 33 primary synthetic hexaploid wheat genotypes (SYN) were crossed to 20 spring bread wheat (BW) ...
