| The resistance of spring barley varieties to powdery mildew, leaf rust, leaf scald and net blotch was characterized by using results from inoculated small-plot nurseries and larger survey plots subject to natural infection. The experiments were conducted in different environments. Both trial types often yielded complementary results with respect to the ranking of varieties suggesting that a recommended variety characterization should include both naturally infected survey-type trials and nursery trials in which the most relevant pathogen isolates and/or isolate mixtures or populations are used for inoculation. Average and median values of the diseased leaf area of a variety were highly correlated with each other and with the genotype main effect determined... |

| Fifty-five spring barley varieties from the German official varieties list were tested for their susceptibility to loose smut (Ustilago nuda) and covered smut (Ustilago hordei) under a simulation of natural infection conditions. For loose smut infection cv. ‘Lawina’ with about 5 % infected plants was used as spreader. In the trial with covered smut 1kg of seeds were shaken with 1g of spores to contaminate the surface of barley seeds before sowing. Only ‘Steffi’ stayed absolutely free from loose smut during two infection cycles at two locations. With an average of 12.6 % plants with loose smut ‘Danuta’ was the most susceptible. Most susceptible to covered smut were ‘Tunika’ with 13.2 % and hulless ‘Taiga’ with 15 % infected plants. Thirteen varieties... |

| Ziel des Projektes ist die Evaluierung von in Genbanken befindlichen genetischen Ressourcen der Brassicaceen auf Resistenz gegen die Mehlige Kohlblattlaus (Brevicoryne brassicae). Es sollen hierbei Formen gefunden werden, die entweder direkt für den ökologischen Anbau geeignet sind oder die Basis für eine Züchtung resistenter Sorten bilden. Der Schwerpunkt soll dabei auf der "Brassica Core Collection" der europäischen Genbanken liegen. Eine kontinuierliche Prüfung von Brassicacea-Jungpflanzen im Gewächshaus (ca. 600 Genotypen), die künstlich mit der Mehligen Kohlblattlaus besiedelt werden, soll die Vorauswahl potentiell resistenter Formen ermöglichen. Diese selektierten Formen sollen im Freiland unter ökologischen Anbaubedingungen geprüft und hinsichtlich... |

| Besides other legumes lupins belong to the local protein crops usuable as feeding stuff in ecologic farming. Therefore an important breeding aim is to provide lupins with high and stable protein content. A non-destructive analysis using near infrared transmittance spectroscopy was developed for determination of protein in single seeds of lupins. Calibration and validation equations were calculated on the basis of 300 single seeds of 3 blue lupins (‘Azuro’, ‘Bolivio’, ‘Boregine’) growing at 3 ecological locations. The estimation of protein content was possible in a range of 15-44% protein with a coefficient of determination (r²) of 0,907 and a standard error of prediction (SEP) of 1,86%. The equation was applied to evaluate the protein content of single... |

| I afhandlingen beskrives principperne for økologisk plantebeskyttelse og der argumenteres for, at en plantesygdom som stinkbrand primært bør forebygges frem for at blive bekæmpet i et økologisk dyrkningssystem. Stinkbrandens biologi analyseres med henblik på at finde mulige forebyggende dyrkningsmetoder. Endvidere undersøges mulige bekæmpelsesmetoder, som er tilpasset økologisk jordbrug. Det konkluderes, at der findes forebyggende metoder, og at det er sandsynligt, at en systematisk udnyttelse af disse vil kunne forhindre hovedparten af problemerne med sygdommen. Det konkluderes endvidere, at der er muligheder for bekæmpelse i økologisk jordbrug, som kan bruges som sikkerhedsnet under dyrkningssystemet. I afhandlingen gengives 6 eksperimentelle... |

| Das Forschungsvorhaben hat zum Ziel, die Wirtschaftlichkeit des ökologischen Säzwiebelanbaus zu verbessern. Dies soll einerseits durch eine standortgerechte Nährstoffversorgung und andererseits durch eine den ökologischen Anbaubedingungen entsprechende Sortenwahl geschehen. Weiterhin sollen die Sorten unter definierten Lagerbedingungen auf ihre Lagereignung geprüft werden. Die Versuchsdurchführung auf Praxisbetrieben, die Durchführung von Feldtagen und Besichtigungen sowie die Einbeziehung der Beratung sollen helfen, die Ergebnisse schnellstmöglich in die Praxis umzusetzen. Auf diese Weise kann die regionale Erzeugung von Zwiebeln erhalten und gestärkt werden. Eine Zusammenarbeit mit dem Forschungsprojekt 03OE056/2 Neue Anbaustrategien bei Zwiebeln als... |

| Fusarium spp. present on spring wheat seeds can infect seedlings and cause reduced plant densities and higher wheat infestations. In the current project, variation between commercially available spring wheat cultivars in their tolerance to Fusarium seedling blight was investigated in a pot and a field trail. Additionally, initial growth rates of cultivars were measured to investigate possible relations with tolerance. Preliminary analysis shows presence of tolerance differences between the spring wheat cultivars in the pot and field experiment. This difference was relatively robust (experiment x cultivar interaction was not significant). Preliminary analysis also showed a relation between tolerance and initial growth rates of cultivars in the field... |

| Increasing trend in organic farming does not seem to have yet attracted the attention of many plant breeders. On the other side, in every cropping system, for every species, best performing cultivars are needed in each macro-ecology. Considering dif-ferent cropping systems, such as open or glasshouse production, main or second crop alternatives, plant breeders have to focus on the genotype-environment and genotype-input interactions. Organic farming is in need of tailor-made genotypes for almost every crop. In fact, in the near future the same amount of organic registered cultivars will be needed as the conventional cultivars. Conducting an immediate single or combined “seed-bed – pot – field test” might be a logical start to de-termine organic... |
