A locus on chromosome 5b carries a gene encoding a metal transporter (tdhma3-b1) with a non-functional variant causing high accumulation of cadmium in grain. The high-cadmium allele, widespread among durum cultivars but undetected in wild emmer accessions, increased in frequency from domesticated emmer to modern durum wheat. The rapid cloning of tdhma3-b1 rescues a wild beneficial allele and demonstrates the practical use of the svevo genome for wheat improvement.

This study reports the new powdery mildew resistance gene pm68that would be a valuable resource for improvement of both common wheat and durum wheat. The co-segregated markers (xdw05–xdw11) developed here would be useful tools for marker-assisted selection (mas) in breeding.
Considering the main distribution area of durum wheat in the mediterranean area, which is characterized by rainy winters and dry summers, the genetic improvement of stress-related traits was usually approached by breeding directly for yield in potential environments subject to low abiotic stress.
Kota, durum wheat is always sown in the spring, though in the milder climates of the world there are strains of winter durum wheat. (1) kubanka, glumes yellowish white, smooth, flow ering glume awned, berries amber color, large, thick in proportion to their length, sutures narrow, m-curving.
Durum wheat quality durum wheat (dw) grain is used to prepare various products in different parts of the world. The acceptability of a new dw variety is greatly influenced by its quality characteristics. Table 3 lists the major products from dw and their quality requirements.
Carotenoids are essential in the human diet for their important functions in health. Besides, they are responsible for the yellow pigments desirable for industrial quality in durum wheat. The remarkable carotenoid content of durum wheat endosperm is mostly due to lutein. However, lutein esters have not been previously detected in durum wheat as in other cereals such as common wheat, tritordeum.
Simultaneous improvement of protein content and grain yield by index selection is possible but its efficiency largely depends on the weighting of the single traits. The genetic architecture of these indices is similar to that of the primary traits. Grain yield and protein content are of major importance in durum wheat breeding, but their negative correlation has hampered their simultaneous.
Another important mapping population was developed at the international maize and wheat improvement center (cimmyt) by crossing a synthetic (amphihexaploid) wheat (aegilops tauschii [syn. Triticum tauschii] x altar 84 durum) to a spring bread wheat cultivar opata 85 and was genotyped at cornell university in the united states.
A small percentage of red kernels was found in the original shipment and red kernels still persist in the variety. - kubanka is grown chiefly in north dakota, south dakota, and in several other.
If the yield of kubanka (durum) averages 25 percent higher than the yield of marquis (common), in areas repre sented by brookings, highmore and eureka, the price of common wheat (hard red spring) must be something more than 25 percent higher than that of durum, in order to be as profitable to produce.
Synthetic hexaploids made by crossing the wild goatgrass wheat ancestor aegilops tauschii, and various other aegilops, and various durum wheats are now being deployed, and these increase the genetic diversity of cultivated wheats.
The increased economic importance of durum wheat stimulated efforts towards the genetic improvement of this crop by using different methods such as intraspecific and/or interspecific hybridization and mutagenesis.

The cimmyt durum wheat breeding program has done an incredible job in combining several resistance genes to the same genetic background. Many of the durum wheat lines carried multiple-race stem rust resistance genes. These durum wheat lines can be evaluated for their performance in important agronomic traits including yield and quality.
