| The possibilities to balance environmental conditions in organic farming systems are strongly restricted as the input of nutrients is limited and no soluble fertilisers and synthetic pestizides are used. These systems require cultivars that are able to adapt to stressful, less controlled and therefore highly variable environments. This study sums up the results of winter wheat cultivars tested under marginal and fertile soil conditions on organic farms in Switzerland. Three were derived from organic, three from conventional breeding programs and two old cultivars. Across three marginal sites, there was a slight trend towards higher yields of the organically bred cultivars. This difference was statistically signifi cant at the lowest yielding site. However,... |

| Winterweizensorten für den Biolandbau müssen an sehr variable Umweltbedingungen angepasst sein. Acht biologisch und konventionell gezüchtete Weizensorten wurden 2007 im DOKLangzeitversuch in CH-Therwil in zwei bio-dynamischen Systemen (BIODYN 1 und BIODYN 2) auf Loess und 2008 auf bio-dynamischen Betrieben in Rheinau (SH) (Sand mit hohem Kiesanteil), Fehraltorf (ZH) (sandiger Lehm) und Vielbringen-Worb (BE) (sandiger Lehm) an marginalen Standorten getestet. |

| Bunt is one of the most devastating diseases of wheat, in Europe and Northern America mainly caused by Tilletia caries and T.controversa, in the warmer climates of the Near East by T.foetida. The generally obligate biotrophic pathogen is trans-mitted by contaminated seeds or can ersist in the soil. Infection occurs at the very first moments after germination of the grain. Once penetrated into the plant, the fungus grows endophytically, remaining undetected until early maturity stages when grains are replaced by spores. Besides yield losses, the malodorant spores contaminate the grains impairing their use as seeds or as food, thereby leading to serious economic losses. Usually the disease is controlled by the use of seed dressings and the use... |

| Winterweizensorten mit Eignung für den Biolandbau müssen an sehr variable Umweltbedingungen angepasst sein. Möglichkeiten, diese Bedingungen in biologischen Anbausystemen zu kontrollieren, sind stark begrenzt, da die Nährstoffzufuhr limitiert ist und keine chemisch synthetischen Pflanzenschutzmittel und leichtlöslichen Mineraldünger eingesetzt werden. Die Züchtungsziele für den Biolandbau weichen teilweise deutlich von den Zielen für den konventionellen Anbau ab. Von besonderer Bedeutung im Biolandbau sind Bestockungsvermögen, Regenerationsfähigkeit nach mechanischer Unkrautbekämpfung, rasche Nährstoffaufnahme, Unkrautunterdrückungsvermögen, Pflanzenhöhe und Resistenz oder mindestens Toleranz gegenüber Blatt- vor allem aber Ährenkrankheiten, ein gut... |

| Winter wheat cultivars for organic farming have to be adapted to highly variable environments. Yield and yield stability, the nutritional value and the bread making quality are here of major importance. Particularly, seed quality, tillering capacity, regeneration ability after harrowing, weed suppression ability, resistance or tolerance against diseases and improved nutrient use efficiency (NUE) under limited nutrient conditions need to be improved by specific breeding efforts (Kunz et al., 2006; Löschenberger et al., 2008). Ten winter wheat cultivars were grown in 2007 in two organic systems of the DOK long-term experiment in CH-Therwil. Eight of these cultivars were tested in 2008 at three organic farms in different pedo-climatic environments in... |
