The investigation was conducted on the experimental field of the Agricultural University - Plovdiv, during the period2010 - 2013 year. The present study includes 24 local and foreign genotypes two-row barley. For the first time havebeen assessed advantages of perspective genotypes as initial material by applying the “Model of quantitative andcomplex assessment” of the breeding lines and varieties in relation to their use in different barley breeding directions.The model was created as a methodology, approach and mathematical expression by Prof. Georgiev (2013) and can beapplied in all cultures. Based on this model there was established the advantages of studied genotypes in thecorresponding direction and combination of beneficial traits in each of them. As a result may be selected the mostperspective varieties for barley breeding, implementation in practice and selection the trends in the most suitableparental forms for hybridization.Analysis of the results reveal five of studied cultivars: Caravela (102.17 p.), Kaskadior (101.30 p.), Neda (103.83 p.)and Gorast (101.0 p.) which exceed the standard (Obzor-95.63 p.) with the highest comprehensive overall assessment,which make them useful for direct application in the malting barley breeding .The advantages of using method was thatallow us not only to estimate the common comprehensive assessment of the studied genotypes as a initial material, butIt gave us the possibility to see exactly in which breeding areas they have strong express traits.
