| 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,... |

| Common bunt, caused by Tilletia caries and T. foetida, is a fungal disease of wheat world wide. Infection, occurring via seed borne teliospores, is generally controlled by the application of seed treatments prior to sowing. Farming systems like organic agriculture with a very limited range of organic seed treatments available rely heavily on common bunt resistance genes within wheat. In the framework of the BIOBREED project an association study in winter wheat was conducted, aiming at the identification of genetic loci linked to resistance towards common bunt in wheat. 152 European wheat cultivars were phenotyped for their resistance reaction for the two consecutive years 2011/12 at Agrologica research station at Mariager. Infection was scored as percent... |

| This paper represents a part of the continuing breeding program for resistance to true loose smut in barley in Bulgaria. It is also a continuation of the paper presented on the 8th European Symposium on organic farming in Kassel 2005. Research on seed-borne diseases started in Bulgaria on barley in the 1960´s at the Institute for barley Re-search in Karnobat. Breeding research especially for a later use in organic farming in Bulgaria started 1998 with the present international project managed by Dr. Todorova. 56 dihaploid lines were derived from F1-hybrids of two barley crosses between resis-tant and susceptible Bulgarian and foreign cultivars bearing the resistant genes Run12 and Run13. The DH progenies were tested in 5 generations for loose smut... |

| Die Verfügbarkeit von ökologisch vermehrtem Saatgut bzw. der Sortenauswahl wird insbesondere bei Gemüse als unzureichend eingestuft. Die verwendeten Sorten sind bei vielen Gemüsekulturen zum überwiegenden Teil Hybriden, die für eine on-farm-Erhaltung ungeeignet sind oder im Falle von aus Zellfusion stammenden CMS-Hybriden nicht mehr fertil und auf Betrieben der Ökolandbauverbände per Richtlinie verboten sind. Diese beiden Aspekte der Saatgutfrage waren maßgebend für die Realisierung dieses Projektes. Mit dem Ziel, die Eignung der Sorten für den ökologischen Gemüsebau zu prüfen, wurden 164 Saatgutmuster noch verfügbarer Populationssorten der Kulturen Kohlrabi (15), Möhren (86) und Porree (63) am europäischen Saatgutmarkt erworben und als Ausgangsmaterial... |

| State of the Art: There is an increasing consumer demand for residue-free, thus organic table grapes from regional production. The cultivation of this fruit species, however, is delicate in humid climates and experience to advice growers still lacking. Definition of the problem: Developing and introducing a new culture of table grapes under Swiss climatic and economic conditions. Project aims: Study of the possibility to produce organic Table Grapes under Swiss climate and economical conditions Methodology: On farm trials, consumers taste test, variety testing and plant protection strategies in replicated field trials. Results, conclusion, state of the art: A quality organic production of Muscat Garnier and Muscat de la Birse has been established.... |

| Die Krankheitserreger Botrytis cinerea und Xanthomonas fragariae sind von besonderer Bedeutung für den ökologischen Erdbeeranbau, gegen die derzeit keine wirksamen Mittel zugelassen sind. Eine Bekämpfung ist nur mit indirekten pflanzenbaulichen Maßnahmen oder dem Einsatz von Pflanzenstärkungsmitteln möglich. Resistente oder tolerante Sorten mit spezieller Eignung für den ökologischen Anbau wären ein effizienter Ansatz zur Verbesserung der ökologischen Erdbeeranbaus. Das beantragte Projekt hat das Ziel, ein bereits bestehendes Programm zur Züchtung von Erdbeersorten für den konventionellen Anbau an die Bedürfnisse des ökologischen Landbaus anzupassen. In diesem Fall werden als Selektionskriterien Resistenzen bzw. Toleranzen gegen die beiden o.g.... |

| Das hier beschriebene Projekt ist Teil eines Verbundvorhabens, das folgende Teilprojekte umfasst: FKZ 11NA001, FKZ 11NA002, FKZ 11NA003, FKZ 11NA004, FKZ 11NA005, FKZ 11NA006, FKZ 11NA007, FKZ 11NA008. Alle in Organic Eprints archivierten Projektbeschreibungen und Veröffentlichungen zu diesem Verbundvorhaben finden Sie unter folgendem Link: http://orgprints.org/cgi/saved_search?savedsearchid=1386. Mit dem Anbau von Sojabohnen in Deutschland sind Vorteile verbunden, die derzeit aufgrund der nicht hinreichenden züchterischen Anpassung der Sojapflanze an unsere Klimate kaum nutzbar sind. Das Forschungsvorhaben macht es sich zum Ziel, einen substantiellen Beitrag zur Verbessserung dieser Situation zu leisten. So soll durch Züchtung geeigneter Sorten... |

| TThree winter wheat composite cross (CC) populations were created in 2001 in the UK consisting either of 20 modern wheat parents (called A population), a subset of 12 high quality parents (Q), or a subset of 9 high yielding parents (Y). Seed of the F4 was transferred to the University of Kassel in 2005 and the populations were grown since then under organic and conventional conditions in well separated large (>100 m2) plots in two parallel sets (12 populations total) without conscious selection applied. In the conventional system fungicides and insecticides were not applied to expose the populations to natural pest and disease pressure. In addition, since the F8 two A populations have been maintained as broadcast sown populations without mechanical weed... |

| Estudos relacionados à desenvoltura de germinação e produção de espécies nativas são essenciais, uma vez que garantem a preservação delas, consequentemente alavancam as questões socioambientais e culturais das comunidades. É nesse intuito que este presente estudo teve como proposta avaliar a germinação de sementes da cagaita (Eugenia dysenterica DC.), espécie frutífera, nativa do Cerrado brasileiro, apreciada pela população, por se tratar de um fruto com potencial diverso. Por ser uma espécie com sementes recalcitrantes, o seu armazenamento para reprodução é considerado um desafio, necessitando de condições que mantenham sua qualidade fisiológica. Sementes dessa espécie apresentam elevado grau de umidade, entre 47% e 53% ao serem dessecadas, perdem... |

| Im Vergleich zum konventionellen Landbau müssen die regionalen Unterschiede von Klima und Bodenbeschaffenheit im ökologischen Landbau mehr berücksichtigt werden. Eine eigene Züchtung für diese Vielfalt der Anbaubedingungen war nicht nur notwendig, weil der Züchtungsfortschritt im konventionellen Landbau immer weniger den Bedürfnissen im ökologischen Landbau entspricht, sondern auch, weil die neueren Züchtungsmethoden – bis hin zur Gentechnik – nicht mit dessen Prinzipien vereinbar sind. Beim Winterweizen sind aus biologisch-dynamischer Züchtung inzwischen anbauwürdige Sorten und Zuchtstämme vorhanden, die für sehr unterschiedliche Standortbedingungen gezüchtet worden sind. Diese „Öko-Sorten“ wurden nun in einem einjährigen Versuch mit Sorten aus der... |
