For proper assessment of the parents involved in the hybridization program and the determination of parental pairs, every breeder needs a proper study on the traits of interest and their interaction in the genome. To successfully combine the features in the new genome and produce new forms it is necessary to use genetically distant forms. In the study for the breeding program we have combined component, cluster, correlation and factor analyses. The results of the morphological characteristics of eight prospective local and introduced materials helped us to identify four genetically distant parental pairs. Four Bulgarian varieties, which are characterized by high productivity, were crossed with four introduced samples. The use of foreign genoplasm was necessary for their protection due to the high resistance of the foreign samples to Fusarium (Fusarium sp.) аnd the spreading bush of their habitus.
