ABSTRACT Isolates of Puccinia triticina collected from durum wheat from Argentina, Chile, Ethiopia, France, Mexico, Spain, and the United States were analyzed with 11 simple sequence repeat (SSR) markers in order to determine the genetic relationship among isolates. These isolates also were compared with P. triticina isolates from common wheat from North America, and an isolate collected from A...

Until now, little attention has been paid to the geographic distribution and evaluation of genetic diversity of durum wheat from the Central Fertile Crescent (modern-day Turkey and Syria). Turkey and Syria are considered as primary centers of wheat diversity, and thousands of locally adapted wheat landraces are still present in the farmers' small fields. We planned this study to evaluate the ge...

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 ...

Wheat stem rust, caused by Puccinia graminis f. sp. tritici Eriks. & E. Henn, can incur yield losses in susceptible cultivars of durum wheat, Triticum turgidum ssp. durum (Desf.) Husnot. Although several durum cultivars possess the stem rust resistance gene Sr13, additional genes in durum wheat effective against emerging virulent races have not been described. Durum line 8155-B1 confers resista...

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 ...

High Cd content in durum wheat (Triticum turgidum L. var durum) grain grown in the United States and Canada presents potential health and economic problems for consumers and growers. In an effort to understand the biological processes that result in excess Cd accumulation, root Cd uptake and xylem translocation to shoots in seedlings of bread wheat (Triticum aestivum L.) and durum wheat cultiva...

Wheat bugs are widely distributed in various areas of Europe, Asia and North Africa. Species belonging to the genus Eurygaster and Aelia pierce wheat kernels affecting protein quality. The effects of these insects’ feeding activity have been studied mainly in bread wheat (Triticum aestivum L.). This study provides information on the degradation of prolamin proteins (glutenins and gliadins) of b...

A PCR-based method was developed to distinguish between durum/common wheat and common wheat by leveraging slight differences of DNA sequence in Starch Synthase II (SS II) coded on wheat A, B and D genomes. A primer pair, SS II ex7-U/L, was designed to hybridize with a conserved DNA sequence region found in SS II-A, B and D genes. Another primer pair, SS II-D 1769U/1889L, was constructed to reco...

The data presented are related to the research article entitled "Comparison of the dietary fibre composition of old and modern durum wheat (Triticum turgidum spp. durum) genotypes" (De Santis et al., 2018) [1]. This article provides details of the structures of the major dietary fibre components, arabinoxylan and β-glucan, in semolina and wholemeal flour of old and modern Italian durum wheat ge...
