| Lupin as a grain crop has been restricted in growing area to more continental conditions due to their indeterminate growth form, which in maritime Northern European areas causes excessive vegetative development, late and uneven ripening and lodging. However, new reduced branching types provides better possibilities for adaptation to these conditions, and preliminary results indicates potential seed yields up to 5-6 tons per ha in the narrowed leafed lupins (Lupinus angustifolius) and an acceptable stable and early ripening. Due to full susceptibility to anthracnose (Colletotrichum gloeosporioides) in white (L. albus) and yellow (L. luteus) their introduction in these environments is doubtful. In these growing areas Botrytis (Botrytis cinerea) and fusarium... |

| Weeds, with their negative influence on both yield and quality, constitute a major problem in the organic production of quinoa, a potential new seed crop for protein feed and human consumption in Europe. To attain effective weed control, mechanical weeding strategies, such as weed harrowing and inter-row hoeing, were studied. Weed harrowing operates over the entire plot with flexible tines, affecting both crop and weeds, whereas inter-row hoeing is performed between the rows, aiming only at the weeds. The study showed that both hoeing and harrowing reduced the quinoa density in one out of two years, whereas there was no effect on quinoa density in the other year. Yield was increased by both methods, but hoeing increased yield more than harrowing due to... |

| Fusarium wilt can cause total crop failure. Evaluation of Ffusarium resistance in heavily infected soil were performed in a grenhouse where the dominant fusarium species in the soil in descending order was F. oxysporum then F. avenaceum, F. culmorum, F. solani, F. gibbosum. Large fusarium wilt presure was observed and fully susceptible lines were completely destroyed by Fusarium wilt caused by F. oxisporum. Segregation in F2 and F3 in L. angustifolius showed that resistant genotypes have two dominant non-allelic resistance genes to wilt. We call this gene Relation to fusarium oxisporum (Rfo1,Rfo2). Susceptible genotypes have either two wild genes (++ ++) or one wild and one dominant resistant gene (++ Rfo2 Rfo2, or Rfo1Rfo1 ++). Crossing ‘++ Rfo2Rfo2’ to... |
