The paper presents current data on the area of organic farms all over the world and in Europe as well as factors influencing the development of this farming system. Among many factors affecting the development of organic production, issues related to the cultivation of varieties are very important in the economic, social and legal context, including methods of breeding allowed for organic farming, conditions for their registration and admission to cultivation and the specificity of certified seeds production. Legal regulations have an impact on the agricultural practices and directions of transformation in organic farming. However, law and procedures must be changed and updated due to the science development and in response to the growing needs of the population. Comparing the conditions and possibilities of breeding varieties and seed production in an organic and conventional system, practically at each stage, organic production is in a worse position. In the light of the possibilities offered by modern genetics, the methods allowed in breeding varieties for ecological purposes, limited to only some techniques are insufficient”. However, they give the opportunity to bring specific values for all modern agriculture as well as the development of science, especially epigenomics.
