Yield and quality of wheat cultivars in organic and conventional farming systems - Is there an influence of the breeding history? 21
Hildermann, Isabell; Fließbach, Andreas; Mäder, Paul.
Organic farmers often use the same wheat cultivars as conventional farmers. Most of these cultivars have been bred under high-input conditions. Organically managed soils frequently do not deliver enough nutrients and fertilizers are limited. Therefore cultivars bred under high-input conditions often cannot perform to the full extent of their high genetic potential. Better nutrient uptake efficiency would be of great value for organic farms and conventional farms, producing under low-input conditions. Studies with winter wheat showed that cultivars, selected directly under organic conditions finally yielded higher under organic conditions than cultivars selected under conventional conditions [1], indicating a successful adaptation to low-input conditions...

Anpassung und Eignung von Composite Cross Winterweizen- Populationen und anderen Phänotypen auf unterschiedliche N-Versorgungsniveaus 21
Weedon, Odette; Lanvers, J.; Wersebeckmann, V.; Purwien, T.; Heinrich, Sven; Finckh, Maria R..
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...

Wenn der Boden müde wird 21
Gelencsér, Tobias; Hohmann, Pierre.
Bei einem hohen Anteil an Leguminosen in der Fruchtfolge treten oftmals ein Ertragsrückgang bei Erbsen, Ackerbohnen und anderen Hülsenfrüchten auf. Man hat es mit der sogenannten Leguminosenmüdigkeit zu tun. Am FiBL wird geforscht, wie die Krankheit erkannt werden kann und welche Massnahmen dagegen helfen.
