| Apfelzüchtung. Neue Sorten sind wichtig für die Konkurrenzfähigkeit in der Obstbranche. Bei den Zuchtzielen stehen die Fruchtqualität und die Eignung für die nachhaltige Produktion (IP, Bio) im Vordergrund. Bei der Resistenz gegen die Pilzkrankheiten Schorf und Mehltau ist eine breite genetische Abstützung wichtig. Die Kombination verschiedener Resistenzen wird an der FAW mit molekularen Markern nachgewiesen (Labor J. Frey). Neu kommt die Züchtung auf Feuerbrandresistenz hinzu. Das Marketing neuer FAW-Sorten erfolgt zusammen mit spezialisierten Firmen in der Schweiz und im Ausland. Genressourcen Obst und Gemüse. Das gesellschaftliche und politische Interesse, die Genressourcen zu sichern, ist gross. Der Bericht des EVD über die Umsetzung des globalen... |

| Crop competition is a key component of an integrated approach to weed management. Variation in competitive ability and competitive traits have been identified in many other crop species, however little work has been done on oats. Trials were carried out over four years at one organic site with five husked and three naked oat varieties. Mid-season Leaf Area Index (LAI) and tillering ability were identified as weed suppressive traits using path analysis. Differences in weed tolerance were found among varieties. Trade-offs may exist between competitive traits and yield potential which could be optimised by limiting competitive traits later in the season. Selection of competitive traits with high heritability, whilst minimising yield penalties, could... |

| Since 1998 RODELIKA is officially registered as a newly bred carrot variety. It had been developed by positive mass-selection over a 13 year period, based on an old-established variety within a farm based biodynamic system. The goal was a fine root with good health and a focus on taste and ability of maturation. Thus a selection-scheme in organoleptic characteristics sweetness and aroma was created. Numerous investigations demonstrate the very high inner quality of RODELIKA. Property rights of this open-pollinated variety are held by the charitable association Kultursaat eV as a common heritage. |

| 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... |

| Production regularity in organic apricot orchards is highly constrained by blossom brown rot caused by Monilinia spp. infections on flowers. Leaf rust (Tranzschelia spp.) development can induce early defoliation, which is detrimental to tree vigour and yield. Copper-based treatments are partially efficient against both diseases but their negative environmental impact should be considered. The choice of cultivars according to disease susceptibility criterions is a key-step towards low-input production systems. This poster presents the susceptibilities to blossom brown rot and leaf rust of 16 apricot cultivars observed during 5 years in two sites. |

| Die Sonnenblume ist die wichtigste Ölpflanze des ökologischen Anbaus. Ziel des Projektes war die Evaluierung von Sonnenblumensorten auf Resistenz gegen Grauschimmel, Korb- und Stängelfäule und gegen den Falschen Mehltau sowie auf die agronomischen Merkmale Achänenertrag, Trockensubstanz- und Fettgehalt der Achänen. Im Rahmen des Projektes wurden 16 Sorten und Testhybriden unter den Bedingungen des ökologischen Landbaus an zwei Standorten mit jeweils 3 Wiederholungen angebaut. Aufgrund des trockenen und heißen Jahres traten in den Versuchen keine Sonnenblumenkrankheiten auf. Die Sorten unterschieden sich am Standort Eckartsweier signifikant in ihrer Leistungsfähigkeit. Am Standort Honau und verrechnet über beide Standorte waren die Unterschiede zwischen... |

| Im Rahmen des BÖL wurde in 2003 das Projekt 03OE178 „Arbeitsnetz zur Weiterentwicklung der Anbaukonzepte im Ökologischen Obstbau“ initiiert. Ziel war es, eine Schwachstellenanalyse zur Optimierung der Anbaukonzepte des ökologischen Obstbaus durchzuführen. Auf dieser Basis konnten erste Ansätze zur Verbesserung vorhandener Anbaukonzepte erarbeitet werden. Dieses Projekt zeichnete insbesondere die enge Vernetzung von Praxisbetrieben, Beratung, angewandter Forschung und Grundlagenforschung sowie fachspezifischen Experten und dem damit verbundenen breiten Wissenspool aus. Um diesen bewährten Weg weiter zu verfolgen bzw. zu entwickeln, gilt es nun, diese bereits vorhandenen, aber auch weitergehende Strategieansätze in den einzelnen Regionen zu entwickeln und in... |

| Siberia's last remaining indigenous breed of domestic cattle, the Sakha Ynaga (in Yakutian language), or Yakutan Cattle, inhabit the lands surrounding the Lena River in Russia's remote Sakha Republic (Yakutia). A Finnish multidisciplinary team of researchers from MTT Agrifood Research Finland and the University of Helsinki's Aleksanteri Institute explored the genetic uniqueness of the Yakutian cattle and the effect of social and cultural factors on the survival of the breed through periods of major upheaval in Russia's history. The findings of this study have now been published in the book Sakha Ynaga - Cattle of the Yakuts. |

| Common wheat bunt (caused by the fungus Tilletia caries or Tilletia foetida) is a disease whose incidence is clearly on the rise in organic farming, jeopardising the balance of the French organic cereal sector. Control methods adapted to organic farming must be found, especially since we know that no seed treatment is 100% effective. The use of varietal resistance appears particularly promising for limiting the spread of the disease. Since 2000, an experiment whose purpose is to assess the resistance of soft wheat varieties to Tilletia caries is conducted each year by the French plant institute, ARVALIS. These experiments make it possible to identify the existence of a wide behavioural variability with respect to this pathogen among the different varieties... |

| Disease assessment is the basis for describing disease resistance characteristics of commercial varieties in national variety lists for all crops where disease is considered a problem. It is well known that ‘disease’ in a specific situation depends on a whole range of interacting hosts, pathogens and environmental conditions. However, the biological complexity conflicts with the wish to express disease resistance characteristics of a variety as a single score per disease. This problem will be illustrated by basic dynamics of growth and senescence of both host and pathogen over time. Disease expressed in terms of absolute diseased leaf area, disease relative to total leaf area or green leaf area will be discussed in general. Two particular problems in... |

| Despite a high turn-over of new peach cultivars, their suitability for organic and low-input systems remains unknown for most of them. Diseases susceptibility is an important criteria to consider since diseases control is a bottleneck to peach production in theses systems. Since 2001, 81 peach cultivars were assessed in 2 experimental sites and 7 on-farm plots. |

| One of the keystones of the organic orchard is the cultivar choice as one element of pest and disease control. However, few exhaustive data sets concerning the cultivar susceptibility to pests and diseases are available for growers. In order to identify cultivars adapted to organic production methods, the susceptibility to scab, aphids and powdery mildew and the agronomic properties of 36 cultivars were assessed in four French sites under different pedo-climatic conditions. Different levels of susceptibility to scab were observed for 23 scab Vf-resistant and 13 other cultivars. In the North of France where Vf resistance is overcome, the Vf cultivars displayed different levels of scab severity. A high variability in the susceptibility to aphids was observed... |
