| 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... |

| Heritable variation is at the heart of the process of evolution. However, variation is restricted in breeding for uniform crop populations using the pedigree line approach. Pedigree lines are successful in agriculture because synthetic inputs are used to raise fertility and control weeds, pests and diseases. An alternative method promoted for exploring the value of variation and evolutionary fitness in crops is to create composite cross populations. Composite cross populations are formed by assembling seed stocks with diverse evolutionary origins, recombination of these stocks by hybridization, the bulking of F1 progeny, and subsequent natural election for mass sorting of the progeny in successive natural cropping environments. Composite cross... |

| This report was presented at the UK Organic Research 2002 Conference. To a major extent, organic farming depends currently on plant and animal varieties that have been bred for non-organic farming and that are often not suited to organic production. This position is inconsistent with a holistic approach to organic agriculture. Organically-bred plant varieties are needed to develop both the potential of organic agriculture and its integrity. A first attempt at developing a concept for organic plant breeding methodology has been proposed. A novel approach to breeding for organic production has also been started. Further development needs a parallel approach to animal breeding for organic systems. |
