Multivariate characterization of breeding value and evaluation of genetic divergence in 5 blackcurrantt (Ribes nigrum L.) varieties are presented. In the study general combining ability effects (GCA) estimated over two years in a full-diallel cross design (Griffing's method) for fruit yield per plant, yield-contributing traits and resistance traits have been elaborated. The multivariate analysis of variance (MANOVA) according to the fixed Grifing's model and canonical variate analysis for GCA effects have been used. The paper is thought mainly as experimental, methodological study on effective using and usefulness of the suggested statistical procedure in researches for plant breeding purposes. The showed results could be also meaningful for blackcurrant breeding
