Cultivars suited for organic agriculture originate from organic plant breeding. 

Organic plant breeding takes a holistic approach in which selection takes place under certified organic conditions, breeding techniques and methods are in line with the principles of organic farming, and breeding aims to establish a viable relationship between plant and living soil and climate. 

Bioverita lists organic breeders in Europe and cultivars from organic plant breeding:

Another useful resource is Engagement.Biobreeding which maps organic breeding initiatives in Europe. This geographic mapping will allow to get an overview of the present breeding activities, to improve networking and exchange between initiatives on European level and to identify breeding gaps.

Organic plant breeding is more than the absence of products of genetic engineering. 

Organic breeding respects the integrity of genome, cell and natural reproductive ability. Therefore, the use of varieties that have been bred pollen sterile by cell fusion (CMS) is not in line with the organic principles.

Organic farming associations collaborate to publish anually a common list of cell fusion free brassicae, including cultivars of cabbage, chicory, radicchio types and sugar loaf.
