Use of genomic estimated breeding values results in rapid genetic gains for drought tolerance in maize
More than 80% of the 19 million ha of maize (Zea mays L.) in tropical Asia is rainfed and prone to drought. The breeding methods for improving drought tolerance (DT), including genomic selection (GS), are geared to ...
Improving global integration of crop research
(American Association for the Advancement of Science, 2017)
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 ...
Adoption analysis of resource-conserving technologies in rice (Oryza sativa)-wheat (Triticum aestivum) cropping system of South Asia
The bread and rice baskets of South Asia feeding 20% of world population are showing stalled production due to fatigued natural resource bases. The present survey assesses the constraints in adoption of integrated crop and ...
Grain yield, adaptation and progress in breeding for early-maturing and heat-tolerant wheat lines in South Asia
Maintaining wheat productivity under the increasing temperatures in South Asia is a challenge. We focused on developing early maturing wheat lines as an adaptive mechanism in regions suffering from terminal heat stress and ...
Application of unmanned aerial systems for high throughput phenotyping of large wheat breeding nurseries
(BioMed Central, 2016)
Background: Low cost unmanned aerial systems (UAS) have great potential for rapid proximal measurements of plants in agriculture. In the context of plant breeding and genetics, current approaches for phenotyping a large ...
Genomic selection for processing and end-use quality traits in the CIMMYT spring bread wheat breeding program
Wheat (Triticum aestivum L.) cultivars must possess suitable end-use quality for release and consumer acceptability. However, breeding for quality traits is often considered a secondary target relative to yield largely ...
Identification and validation of single nucleotide polymorphic markers linked to Ug99 stem rust resistance in spring wheat
(Public Library of Science, 2017)
Wheat stem rust (Puccinia graminis f. sp. tritici Eriks. and E. Henn.) is one of the most destructive diseases world-wide. Races belonging to Ug99 (or TTKSK) continue to cause crop losses in East Africa and threaten global ...
Wheat quality improvement at CIMMYT and the use of genomic selection on it
The International Center for Maize and Wheat Improvement (CIMMYT) leads the Global Wheat Program, whose main objective is to increase the productivity of wheat cropping systems to reduce poverty in developing countries. ...
