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...

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...

Aiganfanmai is a dwarf tetraploid wheat landrace (Triticum turgidum var. turgidum) that stably produces the semi-dwarf trait. Plant height varies from 80-105 cm under cultivation. Compared with tall durum wheat (T. turgidum var. durum) variety Langdon, we found it to have short spikes and seeds, besides a semi-dwarf character. We crossed Aiganfanmai with Langdon to analyze the genetic basi...

Triticum genus encloses several tetraploid species that are used as genetic stocks for expanding the genetic variability of wheat (Triticum aestivum L.). Although the T. aestivum (2n = 6x = 42, AABBDD) and T. durum (2n = 4x = 28, AABB) karyotypes were well examined by chromosome staining, Giemsa C-banding and FISH markers, other tetraploids are still poorly characterized. Here, we established a...

The genus Triticum includes bread (Triticum aestivum) and durum wheat (Triticum durum) and constitutes a major source for human food consumption. Drought is currently the leading threat on world's food supply, limiting crop yield, and is complicated since drought tolerance is a quantitative trait with a complex phenotype affected by the plant's developmental stage. Drought tolerance is crucial ...

comparative assessment of genetic diversity of 122 durum wheat genotypes (triticum turgidum l. var. durum) was performed using 73 ssap polymorphic fragments, 123 aflp polymorphic loci and 104 ssr alleles. ssap and aflp data showed a clear demarcation between the cultivars and landraces and ssr data classified cultivars and landraces according to their origin. furthermore, the estimated genetic ...

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...
