Efficiency of managed-stress screening of elite maize hybrids under drought and low-N for yield under rainfed conditions in Southern Africa
(Crop Science Society of America (CSSA), 2012)
Maize (Zea mays L.) yields in southern Africa are low, due largely to drought and low-N stress. Selection of stress-tolerant genotypes by CIMMYT is conducted indirectly under managed stress conditions, although the selection ...

Genome-wide association for grain yield under rainfed conditions in historical wheat cultivars from Pakistan
(Frontiers, 2015)
Genome-wide association studies (GWAS) were undertaken to identify SNP markers associated with yield and yield-related traits in 123 Pakistani historical wheat cultivars evaluated during 2011–2014 seasons under rainfed ...

Durum wheat: new age for an old crop
(CIMMYT, 1975)
CIMMYT's development of short, widely adapted durum wheats has enhanced the food production prospects of durum-producing nations. Scientists at CIMMYT and in national cereal programs are working together to combine high ...
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 ...

International testing program in wheat, triticale and barley
(CIMMYT, 1979)
In 1950 a stem rust epidemic struck the wheat crop in the United States and Canada, reaching its greatest destruction in 1954. In 1953 the durum wheat crop of the U.S. was 60 per cent destroyed, and in 1954,75 per cent. ...

Genome-wide association study for adaptation to agronomic plant density: a component of high yield potential in spring wheat
(Crop Science Society of America (CSSA), 2015)
Previous research has shown that progress in genetic yield potential is associated with adaptation to agronomic planting density, though its genetic basis has not been addressed before. In the current study, a wheat (Triticum ...

Evaluacion de poblaciones F2 de maiz de alta calidad de proteina en los llanos orientales de Colombia
(Universidad Nacional de Colombia, 2010)
Doscientas cincuenta y tres familias F2 de alta calidad de proteina (ACP) provenientes del CIMMYT (Centro Internacional de Mejoramiento de Maíz y Trigo) fueron evaluadas en dos ensayos diferentes en Menegua, una localidad ...

Mapping smallholder wheat yields and sowing dates using micro-satellite data
(MPDI, 2016)
Remote sensing offers a low-cost method for developing spatially continuous crop production statistics across large areas and through time. Nevertheless, it has been difficult to characterize the production of individual ...

Estimation of physiological genomic estimated breeding values (PGEBV) combining full hyperspectral and marker data across environments for grain yield under combined heat and drought stress in tropical maize (Zea mays L.)
(Public Library of Science, 2019)
High throughput phenotyping technologies are lagging behind modern marker technology impairing the use of secondary traits to increase genetic gains in plant breeding. We aimed to assess whether the combined use of ...

Linkages and interactions analysis of major effect drought grain yield QTLs in rice
(Public Library of Science, 2016)
Quantitative trait loci conferring high grain yield under drought in rice are important genomic resources for climate resilient breeding. Major and consistent drought grain yield QTLs usually co-locate with flowering and/or ...
