Prediction of Genetic Values of Quantitative Traits in Plant Breeding Using Pedigree and Molecular Markers
The availability of dense molecular markers has made possible the use of genomic selection (GS) for plant breeding. However, the evaluation of models for GS in real plant populations is very limited. This article evaluates ...
Rust diseases of wheat: concepts and methods of disease management
Roelfs, A.P., R.P. Singh, and E.E. Saari. 1992. Rust Diseases of Wheat: Concepts and methods of disease management. Mexico, D.F.: CIMMYT. 81 pages. The rust diseases of wheat are among the most studied of the plant ...
Association mapping and gene-gene interaction for stem rust resistance in CIMMYT spring wheat germplasm
The recent emergence of wheat stem rust Ug99 and evolution of new races within the lineage threatens global wheat production because they overcome widely deployed stem rust resistance (Sr) genes that had been effective for ...
QTL analysis of the spring wheat 'Chapio' identifies stable stripe rust resistance despite inter-continental genotype × environment interactions
Chapio is a spring wheat developed by CIMMYT in Mexico by a breeding program that focused on multigenic resistances to leaf rust and stripe rust. A population consisting of 277 recombinant inbred lines (RILs) was developed ...
The emergence of Ug99 races of the stem rust fungus is a threat to world wheat production
Race Ug99 of the fungus Puccinia graminis tritici that causes stem or black rust disease on wheat was first detected in Uganda in 1998. Seven races belonging to the Ug99 lineage are now known and have spread to various ...
Races of Puccinia graminis f. sp. tritici with combined virulence to Sr13 and Sr9e in a field stem rust screening nursery in Ethiopia
North American durum lines, selected for resistance to TTKSK (Ug99) and related races of Puccinia graminis f. sp. tritici in Kenya, became susceptible in Debre Zeit, Ethiopia, suggesting the presence of stem rust races ...
High-density mapping of triple rust resistance in barley using DArT-Seq markers
The recent availability of an assembled and annotated genome reference sequence for the diploid crop barley (Hordeum vulgare L.) provides new opportunities to study the genetic basis of agronomically important traits such ...
