According to the Convention on Biological Diversity every state is responsible for the plant genetic resources (PGR) available in its territory. The PGR collecting missions are the tools for exploration of the genetic diversity in horticultural plants. Local varieties, landraces, escaped forms, wild seedlings and breed material were collected during nine expeditions organised by Pure Horticultural Research Station in the summer of 2003. The most accessions were collected for grapes, apple, sweet cherry, pear and garlic. The total amount of accessions collected in the all expeditions was 452. Some species are under the threat of extinction, such as potato onion (Allium cepa L.). It was observed that some species have broader growing area than it was considered till now. For example, sweet cherry (Cerasus avium (L.) Moench) was found in Gaizins, and black elder (Sambucus nigra L.) in Iedzeni.
