Association Mapping of Resistance to Yellow Rust in Winter Wheat Cultivars and Elite Genotypes
Yellow (stripe) rust, caused by Puccinia striiformis
f.sp. tritici (Pst), is a destructive disease of
wheat (Triticum aestivum L.) all over the world,
particularly in the Central and West Asia and
North Africa (CWANA) ...
Wheat production and breeding in Sub-Saharan Africa: Challenges and opportunities in the face of climate change
Purpose – This paper aims to review the current status of wheat production, farming systems, production constraints and wheat demand-supply chain analysis; the role of international and national breeding programs and their ...
Agronomic Performance of Elite Stem Rust Resistant Spring Wheat Genotypes and Association among Trial Sites in the Central and West Asia and North Africa Region
The new stem rust race Ug99 is an alarming threat to the wheat (Triticum aestivum L.) production of the world for the very fact that it overcomes many of the known Sr genes including the most commonly used genes such as ...
Genome-wide association study for agronomic and physiological traits in spring wheat evaluated in a range of heat prone environments
We undertook large-scale genetic analysis to determine marker-trait associations (MTAs) underlying agronomic and physiological performance in spring wheat using genome-wide association studies (GWAS). Field trials were ...
Breeding progress for yield in winter wheat genotypes targeted to irrigated environments of the CWANA region
The international winter wheat improvement program (IWWIP), an alliance between Turkey–CIMMYT–ICARDA, has distributed improved germplasm to different National Agricultural Research Systems (NARS) partners through international ...
Heat stress in filling stage confers distinct effect on starch granules formation in different thermotolerant wheat accessions
Heat stress affects the accumulation of starch, which is responsible for the major loss in wheat (Triticum aestivum L.) yield. Clarifying the changes of starch composition and granule particles in wheat grain under heat ...
Legume-based rotations have clear economic advantages over cereal monocropping in dry areas
Current land use trends show an increasing preference for monocropping – mostly a consequence of policies and incentives aimed at enhancing the intensification of cereals. This shift has caused some to question whether ...
A SNP marker for the selection of HfrDrd, a Hessian fly-response gene in wheat
The HfrDrd gene has been reported to be induced specifically in the wheat's defence response to Hessian fly larvae and is not a general stress-responsive gene. The gene is located on chromosome 7DS with a homeologue on ...
Institutional and farm-level challenges limiting the diffusion of new varieties from public and CGIAR centers: The case of wheat in Morocco
Low adoption of agricultural technologies slows efforts to increase agricultural productivity and enhance rural livelihoods in developing countries. A large body of literature has sought explanations for the problem, but ...
QTL mapping identifies a major locus for resistance in wheat to Sunn pest (Eurygaster integriceps) feeding at the vegetative growth stage
Sunn pest (Eurygaster integriceps Puton) is the most destructive insect pest of bread wheat and durum wheat in West and Central Asia and East Europe. Breeding for resistance at the vegetative stage of growth is vital in ...
