Organic plant breeding
Provedor de dados: 21
Autores: Wolfe, Martin S.
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.

Evolutionary plant breeding for low input systems
Provedor de dados: 21
Autores: Phillips, Scott; Wolfe, Martin.
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...

Anpassung der regionalisierten Versuchsauswertung mit überlappenden Anbaugebieten für Sortenversuche im ökologischen Landbau
Provedor de dados: 21
Autores: Gruber, Harriet; Zenk, Andrea.
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...

Variety trials of broccoli in organic farms
Provedor de dados: 21
Autores: Kallela, Marja; Peltue, Tiina.
The aim of the organic variety trials on year 2004 was to find good varieties for organic broccoli production and varieties which stand covering cloths as long as possible nearly until harvest.

Untersuchung der Qualität von Saatgut sowie der Wurzel- und  Sprossentwicklung von Getreidekeimlingen
Provedor de dados: 21
Autores: Diethart, Mag. Ivoneta; Weinhappel, Ing. Manfred; Hartl, Dr. Wilfried.
Primary roots and shoots of 13 day old cereal seedlings and quality of seed were  investigated in the frame of the certification process of organic seed produced in  Austria. The germination of seed and the development of seedlings were significantly  affected by Microdochium nivale on wheat, triticale and rye and by Septoria nodorum  on wheat. The number of primary roots was found to be significantly different in wheat  varieties and genotypes but was not influenced by year and region. The number of  primary roots was also positively correlated with the kernel weight of some wheat  varieties.
