Summary

Practical Recommendations
- Start an organic breeding program in your target selection environment, collect information about organic certified areas including their “cultivation history” (e.g. weed infestation from previous years)
- Mimic future cultivation system in the nursery, e.g. by combining spaced plants of target species by under-sowing with the right companion species3
- Do preventive measures for avoidance against pests and weeds in advance, e.g. reduce seed stock of weeds via repeated hoeing
- Identify important traits (e.g. early vigour to enhance weed suppression) for organic cultivation and put special focus on them in your selection2


EPrint Type:Practice tool
What problem does the tool address?:In Switzerland and Europe, if available, organically bred varieties (e.g. Cat. 1 and 2 according to the classification developed by Bio-Suisse1) should be preferred over conventional ones. However, only few organic forage crop varieties exist, and their seed availability is scarce. Breeders need to be encouraged to develop organic forage crop varieties.
What solution does the tool offer?:Being courageous and define new breeding aims
Organic forages must compete well during establishment (no chemical weed control) and should efficiently utilize nutrient resources (no mineral fertilizer)2. Quickly establishing stands of legume-grass mixtures are most appropriate, as they adequately suppress weeds and fix atmospheric nitrogen. In case of high legume ratios in the mixture, it is important to breed legumes with a low content of undesirable ingredients for animal nutrition, like phytoestrogens. For best performing mixtures, it is important to select the components directly together in order to maximize positive interactions for yield, nutritional quality, etc. One example is the selection of spaced alfalfa plants in an under-sowing with tall- and red-fescue (see Figure).
