<jats:title>Abstract</jats:title> <jats:p>Breeding apomictic apple seedling rootstocks in a country where vegetatively propagated material is grown nearly exclusively is a tremendous challenge. When the program was started 25 years ago, virus infection was widespread in apples. Used as rootstocks, seedlings have the advantage of being free from viruses, because these viruses are not seed-transmitted. In Germany, a functional system has been developed to produce and distribute pomologically valuable, virus-free (VF) plant material in quantities sufficient for the nurseryman. The standard of orchard performance for apple rootstocks is high, with the dwarfing M.9 being the most important rootstock in our country. Apomictic seedlings have to compete with this and other horticulturally excellent stocks.</jats:p>
