Abstract:
The success of any breeding program is conditioned by the availability of a large, diverse and valuable germplasm fund.
Its usefulness depends on the proper, complete identification of the genetic resources required in the breeding work.
Identification of the most valuable parents requires an exhaustive study of varietal characteristics and accurate evaluation of all the available genotypes.
This paper gives an overview of the genetic variability within the sour cherry national collections in Romania, and a rationale for prioritizing the use of certain genotypes in controlled hybridizations.
