In recent years, increasingly appreciates the importance of The Plant Genetic Resources for development and success of the plant breeding, agriculture and ecology. Collection of wild wheat species of genus Triticum, which supports, study and stored in the IPGR-Sadovo is represented by 45 plant species. It contains 783 accessions of which 160 samples are Tr. sphaerococcum, 124 Tr. turgidum, 84 Tr. monococcum, 73 Tr. spelta, 60 Tr. bоeoticum, 59 Tr. dicoccon, 30 Tr. polonicum, 22 Tr. dicoccoides, 21 Tr. timopheevi, 13 Tr. carthilicum, 12 Tr. macha, 11 Tr. compactum and 81 from other species. The maintained germplasm diversity from wild wheat species is determined by their regions of origin. The largest part of accessions are from Russia - 97 pieces, Bulgaria - 45 pieces, Germany - 38 pieces, Spain - 16 pieces, USA 13 - pieces, India - 12 pieces, etc. Particular attentions should be paid to wheat originating from Bulgaria. These are the accessions that form the category of original germplasm, whose identity must be controlled in the process of storage and reproduction. Available gene pool is the basis for successful plant breeding improvement working and maintains original germplasm for research.
