Doubled haploids versus conventional breeding in CIMMYT wheat breeding programs
(2013)
Doubled haploid (DH) technology has been used in breeding programs for several decades and is currently the method of choice in a number of crop species, including barley (Hordeum vulgare L.), rapeseed (Brassica napus L.), ...

Genetics of resistance to yellow rust in PBW343 × Kenya Kudu recombinant inbred line population and mapping of a new resistance gene YrKK
(2013)
Yellow or stripe rust, caused by Puccinia striiformis f. sp. tritici, is an important disease of common wheat (Triticum aestivum L.) worldwide. A recombinant inbred line (RIL) population, derived from the cross PBW343 × ...
Article
Earliness in wheat: A key to adaptation under terminal and continual high temperature stress in South Asia
(2013)
High temperatures are a primary concern for wheat production in South Asia. A trial was conducted to evaluate the grain yield performance of high yielding, early maturing heat tolerant CIMMYT wheat lines, developed recently ...
Article
Resistance to stem rust Ug99 in six bread wheat cultivars maps to chromosome 6DS
(2013)
More than 80 % of the worldwide wheat (Triticum aestivum L.) area is currently sown with varieties susceptible to the Ug99 race group of stem rust fungus. However, wheat lines Niini, Tinkio, Coni, Pfunye, Blouk, and Ripper ...

QTL mapping of slow-rusting, adult plant resistance to race Ug99 of stem rust fungus in PBW343/Muu RIL population
(2013)
Races of stem rust fungus pose a major threat to wheat production worldwide. We mapped adult plant resistance (APR) to Ug99 in 141 lines of a PBW343/Muu recombinant inbred lines (RILs) population by phenotyping them for ...
Article
Genetic analysis of adult plant resistance to yellow rust and leaf rust in common spring wheat Quaiu 3
(2013)
Identifying and utilizing rust resistance genes in wheat has been hampered by the continuous and rapid emergence of new pathogen races. A major focus of many wheat breeding programs is achieving durable adult plant resistance ...
Article
QTL analysis of the spring wheat 'Chapio' identifies stable stripe rust resistance despite inter-continental genotype × environment interactions
(2013)
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 ...
Article
Quantitative trait loci of stripe rust resistance in wheat
(Springer Verlag, 2013)
Key message: Over 140 QTLs for resistance to stripe rust in wheat have been published and through mapping flanking markers on consensus maps, 49 chromosomal regions are identified. Abstract: Over thirty publications during ...
Article
Resistance to multiple cereal aphids in wheat-alien substitution and translocation lines
(2013)
Rhopalosiphum padi, Schizaphis graminum, and Sitobion avenae are three of the most destructive aphid species of wheat (Triticum aestivum L.). They can significantly reduce wheat yields directly by feeding and indirectly ...
