Wheat occupies a special role in global food security since, addition to providing 20% of our carbohydrates and protein, almost 25% the production is traded internationally. The importance wheat for was recognised by Chief Agricultural Scientists G20 group countries when they endorsed establishment Initiative 2011. tasked with supporting research community facilitating collaboration, information resource sharing helping build capacity address challenges facing an increasingly variable...
Summary Infection with endophytic fungi (Acremonium spp.) was detected in wild populations of Lolium spp. from 15 20 European countries. Of 523 examined, 38% contained no infection, 48% 1–50% infection and 14% 51–100% infection. Level slightly but significantly associated abundance the sward. For data France, significant correlations were obtained between level five climate variables; highest evapotranspiration (0.66, P < 0.001) water supply deficit (‐0.66, 0.001). A model established...
Genomic selection is focused on prediction of breeding values candidates by means high density markers. It relies the assumption that all quantitative trait loci (QTLs) tend to be in strong linkage disequilibrium (LD) with at least one marker. In this context, we present theoretical results regarding accuracy genomic selection, i.e., correlation between predicted and true values. Typically, for individuals (so-called test individuals), are markers, using marker effects estimated fitting a...
Five genomic prediction models were applied to three wheat agronomic traits—grain yield, heading date and grain test weight—in breeding populations, each comprising about 350 doubled haploid or recombinant inbred lines evaluated in locations during a 3-year period. The accuracy, measured as the correlation between estimated value observed trait, was range of previously published values for yield (r = 0.2–0.5), trait with relatively low heritability. Accuracies weight, high heritabilities,...
We develop a simple mathematical model to explain the lower than expected levels of infection wild perennial ryegrass populations in France by endophytic Neotyphodium fungi (formerly named Acremonium). Indeed, seed-borne endophytes are considered as mutualistic symbionts, because they increase survival, growth and flowering rates their hosts, should therefore be present at very high frequencies all host populations. However, recent surveys have shown that 70% harbour such France. Moreover,...
Having a well-known history of genome duplication, rice is good model for studying structural and functional evolution paleo duplications. Improved sequence alignment criteria were used to characterize 10 major chromosome-to-chromosome duplication relationships associated with 1440 paralogous pairs, covering 47.8% the genome, 12.6% genes that are conserved within sister blocks. Using micro-array experiment, genome-wide expression map has been produced, in which 2382 show significant...
Cross‐validation (CRV) methods were designed to simulate genomic selection (GS) for yield in a wheat ( Triticum aestivum L.) breeding program with data of 318 genotypes grown over an 11‐yr period at six locations France. Two methods, CVSWO (cross‐validation‐specific without location as factor) and CVSW factor), included 11 folds, each comprising during specific year representing target populations, while the remaining folds other 10 yr represented training populations. These compared CVRWO...
