Lr39 + Pm21: a new effective combination of resistance genes for leaf rust and powdery mildew in wheat
Blumeria graminis gene pyramiding Puccinia triticina
2014/2/24
Two effective resistance genes were introduced, one for leaf rust (Lr39) and the other for powdery mildew (Pm21), into the susceptible German wheat cv. Lexus. Molecular selection of plant material was...

Genetic analysis of preharvest sprouting tolerance in bread wheat (Triticum aestivum L. emend. Thell.)
Preharvest sprouting ermination index iallel cross, enetic parameters read wheat editerranean region
2011/3/22
Rains during grain ripening in wheat (Triticum aestivum L.) can cause preharvest sprouting (PHS), which drastically affects the grain yield and the baking quality of flour. In the present study, to sc...
The HLP mutation confers enhanced resistance to leafrust in different wheat genetic backgrounds
Hypersensitive Response LesionMimic Mutant Puccinia Triticina,Wheat Commercial Stocks
2013/3/5
In several plant species, lesionmimic mutants simulate the diseaseresistance response in the absence of pathogens. Interestingly, some of these mutants confer broadspectrum resistance to diverse patho...
