Genetic analysis of water-logging tolerance in tropical maize (Zea Mays L.)
Approximately 80% of maize (Zea mays L.) in South and Southeast Asia is grown as a rain-fed crop, where temporary excessive soil moisture or water-logging during the summer-rainy season is one of the major production ...
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 ...
QTL mapping of slow-rusting, adult plant resistance to race Ug99 of stem rust fungus in PBW343/Muu RIL population
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 ...
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 ...
Investigating the efficiency of the single backcrossing breeding strategy through computer simulation
A strategy combining single backcrossing with selected bulk breeding has been successfully used in wheat improvement at CIMMYT to introgress rust resistant genes from donor parents to elite adapted cultivars. In this ...
