C admium (Cd) is a nonessential heavy metal that can cause kidney problems. Diet is the main source of Cd for nonsmokers, with cereal products, including pasta, accounting for up to 20% of the daily intake of Cd. The current official standard for maximum level of Cd in durum wheat grain as stated by the Codex Alimentarius Commission is 0.2 ppm. The European Union has adopted this level as the m...

heat stress is one of the main obstacles for crop production in many areas of the world including southwest of iran. in order to evaluation the effect of heat stress on yield, yield component, and mopho-phenological traits of wheat, an experiment was conducted during 2010-2011 under normal (optimum sowing date) and heat stress (late sowing date) conditions on 11 wheat genotypes including yavaro...

ABSTRACT A total of 78 isolates of Puccinia triticina from durum wheat from Argentina, Chile, Ethiopia, France, Mexico, Spain and the United States and 10 representative isolates of P. triticina from common wheat from the United States were tested for virulence phenotypes on seedling plants of 35 near-isogenic lines of Thatcher wheat. Isolates with virulence on lines with leaf rust resistance g...

Brassicaceae oilseeds can serve as potential feedstocks for renewable biofuels to offset demand for petroleumbased alternatives. However, little is known about oilseed crop yield potential and N use in semiarid, wheat (Triticum spp.)-based cropping systems that dominate the northern Great Plains (NGP). A 5-yr study was conducted in northeast Montana to investigate the yield potential of a direc...

The action of species cytoplasm specific (scs) gene(s) can be observed when a durum (Triticum turgidum L.) nucleus is placed in the Aegilops longissimum S. & M. cytoplasm. This alloplasmic combination, (lo) durum, results in nonviable progeny. A scs gene derived from T. timopheevii Zhuk. (scs(ti)) produced compatibility with the (lo) cytoplasm. The resulting hemizygous (lo) scs(ti)- durum line ...

MicroRNAs (miRNAs) are small non-coding RNAs that play critical roles in plant development and abiotic stress responses. The miRNA transcriptome (miRNAome) under water deficit stress has been investigated in many plant species, but is poorly characterised in durum wheat (Triticum turgidum L. ssp. durum). Water stress during early reproductive stages can result in significant yield loss in durum...

After nitrogen stress, phosphorus is the second most widely occurring nutrient deficiency in cereal systems around the world. The objectives of this study were: (1) to look at the effect of changes in phosphorus use efficiency and responsiveness on grain yield and quality of triticale and durum wheat with respect to an old tall durum wheat of the early 1940s, Barrigon Yaqui. A two-year field ex...

in western canada, durum wheat cultivars (triticum durum) have low to moderate lev-els of seed dormancy and are susceptible to pre-harvest sprouting. the aim of this study was to evaluate the dormancy level of canadian durum wheat cultivars and to identify tetraploid wheat accessions with elevated levels of seed dormancy. first, the level of seed dormancy and length of after-ripening of 17 nort...
