Septoria tritici blotch (STB), caused by the fungus Zymoseptoria tritici, is a major constraint in global wheat production. The lack of genetic diversity modern elite cultivars largely hinders improvement STB resistance. Wheat landraces are reservoirs untapped diversity, which can be exploited to find novel resistance genes or alleles. Here, we characterized 188 Swiss for using four Z. isolates...

Triticum tauschii) (Thomas and Conner, 1986; Whelan and Thomas, 1989) and the Cmc2 gene transferred to To diversify the genetic base of resistance in wheat (Triticum aesti6D from Agropyron elongatum (Host). Beauv. (Martin vum L.) to the wheat curl mite (WCM), Aceria tosichella Keifer, resiset al., 1976; Whelan and Hart, 1988). An unnamed gene tance to this pest was transferred from the dipolid ...

Pasta are important foods in Europe, mainly in ltaly (25 kg/capita/year), Greece, France (6 kg) and Spain . The best products (nutritional value, cooking quality, aspect) are processed from durum wheat semolina . Because of this difference in quality, and because of the new market regulation on January 1993, that will include a free circulation between the member States of pastas made of durum ...

Increasing grain yield potential in wheat has been a major target of most breeding programs. Genetic advance has been frequently hindered by negative correlations among yield components that have been often observed in segregant populations and germplasm collections. A tetraploid wheat collection was evaluated in seven environments and genotyped with a 90K SNP assay to identify major and stable...

The allelic variation at seven prolamin loci involved in quality has been studied in a set of durum wheat landraces from all the Spanish regions where this crop has been traditionally cultivated. The genetic variability was higher than that found in other germplasm collections. All the loci, except Glu-B2, displayed a genetic variability higher than 0.62, with Glu-3 the most polymorphic. In tot...

Durum wheat (Triticum durum Desf.) breeding programs face many challenges surrounding the development of stable varieties with high quality and yield. Therefore, researchers breeders are focused on deciphering genetic architecture biotic abiotic traits aim pyramiding desirable traits. These efforts require access to diverse resources, including wild relatives, germplasm collections mapping popu...

Aegilops sharonensis Eig (Sharon goatgrass) is a wild diploid relative of wheat within the Sitopsis section of Aegilops. This species represents an untapped reservoir of genetic diversity for traits of agronomic importance, especially as a source of novel disease resistance. To gain a foothold in this genetic resource, we sequenced the cDNA from leaf tissue of two geographically distinct Ae. sh...

We hypothesize that institutions such as agricultural cooperatives influence regional levels of variety diversity through input supply, processing or marketing functions. This diversity can also affect yield, a partial measure of crop productivity. We test these hypotheses with data from southern Italy, a mega-diversity spot and centre of diversity for durum wheat. Cooperatives in the southern ...
