The activities on collecting and regeneration were carried out by above mentioned institutions.

Each member of working group collected certain number of accessions. Accessions collected during the 2005 and 2006 were put in the joint collection field at College of Agriculture in Križevci 2007 where identification made. For most of them regeneration were made and the seed was prepared for long term storage.
