Preservation of old varieties and wild relatives of crop plants is a global priority, recognized by the UN (2015), FAO (2011), the Convention on Biological Diversity (UN CBD, 2010), and the EU Biodiversity Strategy for 2030. These genetic resources offer adaptive capacities to address climate change impacts on food security amid projected population growth to over 9 billion by the end of the century. According to FAO (1998), 75% of plant genetic diversity has been lost due to intensive agriculture, urbanization, and trade in wild plants. In Bulgaria, anthropogenic pressure and changes in land use have led to the near-extinction of local species.

The project aims at sustainable management of maize and perennial fodder grass genetic resources (old local varieties, tripsacum, teosinte; Lolium perenne, Festuca pratensis, F. arundinacea, F. rubra, Festulolium, Dactylis glomerata, Agropyron cristatum, A. desertorum). Results include: enrichment of collections at the National Genebank of IPGR-Sadovo; a database with taxonomic, eco-geographical, and evaluative characteristics; enhancement of breeding processes through expanded genetic diversity; reporting at scientific forums.

This will support farmers and breeders, promoting climate-resilient varieties, reducing genetic erosion (CBD Target 13), and boosting team capacity for future projects, including young researchers' dissertations. The outcomes align with Bulgaria's National Strategy for R&D 2017-2030 and priorities for food security and environmental protection.
