Analysis of durum wheat germplasm adapted to different climatic conditions

Durum Wheat (Triticum Durum Desf.) Lines Show Different Abilities to Form Masked Mycotoxins under Greenhouse Conditions

Deoxynivalenol (DON) is the most prevalent trichothecene in Europe and its occurrence is associated with infections of Fusarium graminearum and F. culmorum, causal agents of Fusarium head blight (FHB) on wheat. Resistance to FHB is a complex character and high variability occurs in the relationship between DON content and FHB incidence. DON conjugation to glucose (DON-3-glucoside, D3G) is the p...

Participatory design of livestock systems adapted to new climatic conditions

Climate change progressively makes obsolete the current agricultural production strategies built with respect to previous landmarks of average and extreme climatic situations. In order to remain viable in the expected climatic context farming systems will need to evolve both in their structure and management. Because farmers and extension services are the primary actors in agricultural producti...

Genetic Diversity Revealed by Single Nucleotide Polymorphism Markers in a Worldwide Germplasm Collection of Durum Wheat

Evaluation of genetic diversity and genetic structure in crops has important implications for plant breeding programs and the conservation of genetic resources. Newly developed single nucleotide polymorphism (SNP) markers are effective in detecting genetic diversity. In the present study, a worldwide durum wheat collection consisting of 150 accessions was used. Genetic diversity and genetic str...

Variability in glutenin subunit composition of Mediterranean durum wheat germplasm and its relationship with gluten strength

The allelic composition at five glutenin loci was assessed by one-dimensional sodium dodecyl sulphate polyacrylamide gel electrophoresis (1D SDS-PAGE) on a set of 155 landraces (from 21 Mediterranean countries) and 18 representative modern varieties. Gluten strength was determined by SDS-sedimentation on samples grown under rainfed conditions during 3 years in north-eastern Spain. One hundred a...
