The studies were conducted in the Experimental field of the Institute of Plant Genetic Resources (IPGR) in Sadovo during the period 2008-2010. Ninety-eight accessions of Tr. aestivum L., stored for more than 20 years in the National gene bank of IPGR-Sadovo, were investigated. The samples were evaluated on morphological and agronomic traits according to international descriptors lists. Both correlation and multiple linear regression analyses were implemented to establish statistically proven interdependencies of the main yield structural components. PC-analysis was applied to group accessions according to similarity on the basis of five traits in two components in the factor plane. An assessment information database of regenerated accessions was created.
