Resumo: | For further optimisation of organic agricultural systems, more focus is required on  organically produced seeds and the development of better adapted varieties.  Organic plant breeding and seed production need to comply with the concept of  naturalness as applied in organic agriculture, which not only includes the nonchemical  and agro-ecological approaches, but also the integrity of life approach.  As organic environments are less controllable and are more variable, breeding  should aim at improved yield stability and product quality by being adapted to  organic soil fertility as well as sustainable weed, pest and disease management.  Also the ability to produce economicacceptable seed yield avoiding seed-borne  diseases should be included. On the short term, organic plant production can gain  better yield stability by increasing within-crop diversity by the use of mixtures of  conventionally bred varieties or crop populations. Because of expected genotype  by environment interaction more research is needed to define the best selection  environment for selecting organic varieties. To arrive at better adapted varieties for  organic farming systems the role of practical participatory plant breeding may be  crucial.  Although organic farming is clear on excluding the use of genetically modified  organisms and their derivates, the use of molecular markers is still under debate.  Questions arise with respect to their efficiency in selecting the most important  organic traits, such as yield stability, and on the compounds and substances to  produce and apply them. A major concern for a GM-free organic agriculture is an  increasing contamination with genetically modified organisms in organic  production and products, i.e., the problems related to co-existence of GM and non-  GM agriculture. This paper discusses some important factors with regard to  possible impact of co-existence on organic farming. Perspectives to a global scale  of organic plant breeding and seed production are given from a European point of  view.
