| Plant breeding activity has to be considered in the context of the agricultural system. The organic agriculture (OA) is more than a way of production: it is consistent with an ethics of the place and role of the man in the nature. Working for OA means to prefer a holistic approach with a ecological vision of the plant and animal in their environment to an analytic approach with a biochemical vision of the living beings. The variety plays at least two roles in the organic way of production: (i) an ecological adaptation of the crop and the keeping of the environment equilibrium in the planting, (ii) a valorisation of products from a soil and a savoir-faire. Moreover, the breeders have to take in account the respect of the natural crossing barriers and the... |

| Organic Agriculture is especially affected by the increasing spread of stem rust in rye (Puccinia graminis f. sp. secalis) because there is a lack of resistant cultivars in Germany. To analyze the virulence situation of rye stem rust, 71 single-pustule-isolates were established and 30 of those were tested with a differential set consisting of 19 lines. The isolates could be classified into 22 different pathotypes. Only seven pathotypes could be found more than once. Most of the isolates showed a complexity of five virulences. In a preliminary analysis a Simpson index of 0,98 was found indicating a high level of diversity of German stem rust populations. Nine of 19 tested lines reacted fully resistant in seedling stage. In 2011, 70 and 30 rye populations,... |

| Wie bereits 2001 hat der Ökoring Schleswig-Holstein auch in diesem Jahr Komplettuntersuchungen von Rohproteingehalten und essentiellen Aminosäuren über SALVANA bei der Degussa durchführen können. Jochen Hochmann, Landwirtschaftskammer Schleswig-Holstein, hat Proben aus dem diesjährigen Öko-Erbsenversuch am Lehr- und Versuchszentrum Futterkamp zur Verfügung gestellt. Zu erkennen ist, dass in diesem Jahr die Rohproteingehalte im Vergleich zum Vorjahr deutlich niedriger ausfallen. Es kann im Mittel von ca. 2% geringeren Rohproteingehalten ausgegangen werden. Auch die Gehalte an essentiellen Aminosäuren liegen vielfach niedriger, insbesondere im Bereich des Lysins und Threonins. Ursache für die niedrigeren Rohproteingehalte ist insbesondere der nasse und... |

| 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... |

| Wheat genetic resources may be grown in organic farming systems or in less favourable areas for bread wheat species. Characteristics of hulled wheat species (23 varieties of einkorn, emmer wheat, spelt wheat) were studied and evaluated within a two-year trial period (which was executed on certified organic fields) and they were compared to characteristics of landraces and modern bread wheat varieties. The main aim of our study was to evaluate the potential uses of genetic resources of wheat in organic farming. The hulled wheat species were resistant to mildew and brown rust. Their grains were less contaminated with DON than the grains of the control varieties. The grain yield rate was reduced. Per hectare crude protein yield was higher in spelt and emmer... |

| 15 wheat and 4 spelt varieties suitable for ecological farming have been cultivated and tested for susceptibility to common bunt of wheat (T. caries). The 2-years randomized field trials have been carried out at 1 site, with 4 replicates and 10 m row length on naturally infested fields with T. caries. Sowing, weed control and harvesting was done by hand. The number of infested ears has been counted and the number of spores per kernel or spelt has been determined according ISTA. The infestation by wheat of the highest (Elixer, Meister) and lowest (Butaro, Florian) susceptible wheat varieties was higher than 10,000 and lower than 1,000 spores per kernel, respectively. The four spelt varieties had the lowest infestation significantly below 100 spores per... |

| Der in den meisten Bundesländern eingeschränkte Umfang an Sortenversuchen im ökologi-schen Landbau erschwert eine regionale Sortenempfehlung. Die vielfach geringere Ver-suchspräzision in diesen Anbausystemen verschärft das Problem, welches in häufig hohen Standardfehlern und großen Grenzdifferenzen seinen Ausdruck findet. Daher war es erforderlich auch für die Auswertung der Sortenversuche im ökologischen Landbau Anbaugebiete zu bilden und eine überregionale Auswertung unter Einbeziehung der Ergebnisse benachbarter Anbaugebiete vorzunehmen. Ein weiterer Schritt war die Einführung der Hohenheim-Gülzower Serienauswertung. Mit Hilfe der Regionalisierung und gegebenenfalls gewichteten Einbeziehung von Versuchsergebnissen angrenzender Gebiete (Überlappung) kann... |

| Evolutionary breeding through the introduction of composite cross populations (CCPs)encourages intra-specific diversity and increases diversity in the agricultural landscape. Increased genetic diversity in crops may help to buffer both biotic and abiotic stresses and will play an increasingly important role in unpredictable climatic conditions become more unpredictable (Østergård et al. 2009). A number of CC winter wheat populations, commercial varieties and CCP line selections were tested at the University of Kassel, under differing N input levels in order to test past adaptation and suitability to differing fertilisation levels. The CCPs have been managed since 2005 under both organic and conventional conditions without conscious selection. Genetically... |

| Eine wichtige Anpassung an den ökologischen Anbau ist eine zügige Frühentwicklung und ein Wurzelsystem, das an organische Düngung angepasst ist. Eine Halbdiallelkreuzung aus insgesamt 20 europäischen Winterweizensorten wurde 2001 hergestellt und insgesamt drei Subpopulationen aus neun Hochertragseltern (CY), eine mit 12 Backqualitätseltern (CQ) und eine aus allen Eltern (CYQ) zusammengestellt. Seit der F5 wird Saatgut unter konventionellen und ökologischen Anbaubedingungen in jeweils zwei parallelen Populationen getrennt nachgebaut. Saat jeder Generation wird bei -20o C aufbewahrt. Für die Versuche wurden Generationen F6, F10, F11, F15 in einem Feld zu F6.1, F10.1, F11.1, F15.1 vermehrt. Frisches Saatgut wurde im Hydrokultursystem zwei Wochen bei 18/12 oC... |

| DNA markører findes på kontaktfladen mellem molekylær genetik og klassisk planteforædling. De kan bruges til de følgende formål: (1) sortsidentififikation, (2) Kvantificering af genetisk diversitet, (3) molekylær detektering af enkelt-gen egenskaber, (4) molekylær detektering af kvantitative egenskaber, (5) selektion i "widecrosses". Disse anvendelsesmuligheder beskrives nærmere i artiklen. I bruges DNA-markører allered i mange forædlingsvirksomheder. I Danmark bruges dem primært til at teste of virusresistens og til at undersøge nedarvning af specifikke kromosomfragmenter gennem forædlingsprocessen. |
