| 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... |

| L. angustifolius genotypes susceptible to Fusarium root rot and wilt can be grown in new lupin land without disease symptoms, however, lupin root rot and wilt pathogens build up during repeated cropping of susceptible lupins in the same field. After four lupin crops symptoms of root rot and wilt began in an inhomogeneous pattern over the field, and after another three lupin crops susceptible lupins are destroyed before flowering homogeneously over the field and caused total crop failure. The dominating pathogens isolated from diseased lupins with root rot and wilt symptoms in this field are in descending order F. oxisporum, F. solani, F. culmorum, and F. avenaceum, the latter only being isolated from young autumn sown plants. A core collection of lupin... |

| Because of the interdiction of chemical seed treatment, smut resistance is a main demand for cultivation of winter barley in organic farming. A comparison of common high yielding varieties with those chosen particularly with regard to good smut-resistance or tolerance showed no significant differences in field performance under the conditions of organic farming. Main criteria were the yield of grain and the content of protein and most important amino acids for animal nutrition (Cystine, Lysine, Me-thionine, Threonine, Tryptophan). Besides this the degree of shading weeds was estimated by means of measuring leaf areas and lengths of stalks. The leaf area proved to be the main factor. The availability of smut resistant or tolerant varieties out of organic... |

| Die Resistenzzüchtung bei Kartoffeln gegenüber Phytophthora infestans hat für die Konzeption einer nachhaltigen Landwirtschaft und im Kampf gegen den Hunger weltweit hohe Priorität. Es gibt heute gute Aussichten dafür, durch Resistenzzüchtung etwa 30% des derzeitigen Fungizideinsatzes zu ersetzen. Die Aufnahme der Merkmale relative Kraut- und Braunfäuleresistenz in Programme der Sortenzüchtung erfordert wegen des ungünstigen Erbgangs mehr als eine Verdopplung der Sämlingspopulationen, um geeignete Nachkommen selektieren zu können. Die nötigen Phytophthora-Resistenzprüfungen verlangen hohen Arbeitsaufwand und hohe fachliche Qualifikation. Der züchterische Schwierigkeitsgrad und der zu erbringende, erhebliche zeitliche Vorlauf machen die Bearbeitung dieses... |

| An zwei Standorten des Ökologischen Landbaus (Neu-Eichenberg, Nordhessen: mittlerer bis schwerer Boden; Queck, Osthessen: leichter Boden) wurden Feldversuche mit Möhren durchgeführt, um sechs samenfeste Sorten und sechs Hybriden auf ihre Anbautauglichkeit zu prüfen. Außer der Roh- und Handelswarenerträge wurden die Einheitlichkeit des Erntegutes (cv%) bestimmt und die Gehalte an Mineralstoffen (K, Ca, P, Mg) und Zuckern (D-Glucose, D-Fructose, Saccharose) analysiert. Auch sogenannte Bildschaffende Methoden (Kupferchloridkristallisation, Steigbild, Rundfilterchromatogramm) kamen zur Anwendung. Die untersuchten Hybriden erzielten Mehrerträge von 25 bis 29% und in den meisten Fällen auch gleichmäßiger lange Rüben als die Samenfesten. Die... |

| Inden for ganske få år forventes det, at GM sorter af raps vil blive dyrket i Dannmark. Raps er en af de danske afgrøder, der har det største potentiale for genspredning. Det er derfor nødvendigt at løse de sameksistensproblemer der vil opstå, når GM raps dyrkes i nærheden af økologisk raps og ikke-GM raps. I hvilken grad agerkål og spildraps og urenheder i certificeret rapsfrø bidrager til forekomsten af GM under forskellige forhold, undersøges i et igangværende projekt på Risø og KVL. |

| 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... |

| Danish wheat varieties are tested on a set of different Tilletia populations for their level of resistance. Resistance to bunt is studied by inoculating seeds artificially with different populations of bunt before sowing. 5 g of spores per kg of seeds is used, and the ”isolates” used are selected among the 50-60 different populations of bunt collected from different parts of the country. 2-3 different populations are used for inoculation the first year, and varieties showing good resistance are tested further in the following years on 3-6 new populations. The susceptible variety Herzog (up to 86% attack) and the highly resistant variety Stava (normally 0-0.2% attack) are included every year as reference. In July the number of ears with attacks of bunt is... |

| Das Forschungsvorhaben hat zum Ziel, die Sicherheit und damit die Wirtschaftlichkeit des Industriemöhrenanbaus zu verbessern. Dies soll einerseits durch die entsprechende Sortenwahl und andererseits durch direkte, den ökologischen Anbaubedingungen entsprechende Pflanzenschutzverfahren (Behandlung des Saatgutes, Ausbringen von Pflanzenstärkungsmitteln und Pflanzenschutzmitteln) geschehen. Die Vermeidung des Anbaus von für Alternaria anfälligen Sorten ist in ökologischen Anbauverfahren als Basis jeder Regulierungsstrategie anzusehen, da diese Vorgehensweise am ehesten den Vorstellungen der ökologischen Landwirtschaft entspricht. Da es im Bereich der Sorten für den Industriemöhrenanbau jedoch bisher nur mehr oder weniger starke Anfälligkeiten für Alternaria... |
