| In context of a larger project dealing with the traits of barley that are related to organic farming (BAR-OF), we performed an association mapping in order to dertermine the genetic loci linked with the respective traits. In two subsequent years (2002 and 2003), we used field results from 96 barley lines and varieties, partially overlapping between the years. The lines/varieties were grown on three Dansih locations (Flakkebjerg, Foulum and Jyndevad). For Foulum and Flakkebjerg, we observed both fields grown under organic and conventional regime; for Jyndevad only fields cultivated under organic conditions were ecploited. Neither in the organic nor in the conventional fields; diseases were controlled chemically. In the resulting five environments per year,... |

| In a variety mixture, competition between component varieties as well as differences in performance of the components may lead to changes in the proportion of component varieties between seed sown and seed harvested. This will imply that farm saved seeds of variety mixtures will constitute an evolving population. How much changes are found over a short period of years and in different environments? In 2002, six 3-component variety mixtures of spring barley were constructed based on altogether 14 mostly high-yielding varieties. The six mixtures and derivatives of these were included in the large Danish BAR-OF variety trials in the years 2002-2005 (Østergård et al. 2005). Here, a subset of this material is considered: only trials from 2003 and 2004 at the... |

| 455 wheat varieties and breeding lines were grown in the field,contaminated with 7 to 11 different races of common bunt. Based on the reaction of the lines to the different virulence races, it was possible to group the lines by differential varieties with known resistance genes, indicating that they may have one or two of the resistance genes Bt1, Bt2, Bt5, Bt7, Bt13, BtZ or Quebon-resistance. Based hereof, genetic markers will be developed using a genome-wide association study (GWAS). |
