Being one of the most important oil crops in the world main goals in sunflower breeding are
increased seed and oil yield per hectare. Bearing in mind breeding direction and global importance
of this oil crop objective of this study was to evaluate general combining ability (GCA) of six
sunflower genotypes and specific combining ability (SCA) of their crosses as well as to estimate
components of genetic variability for seed yield/plant. Genotypes were crossed according to
incomplete diallel method (without reciprocals) and fifteen F1 progenies were derived. Both,
additive and non-additive, genetic components were significant in seed yield expression but
according to GCA/SCA ratio additive component was more important. The highest GCA value was
recorded in G1 genotype, while the highest SCA value was recorded in combination G2xG3, for
seed yield. Analysis of components of genetic variability revealed that dominant gene effects (H1)
were more important than additive (D...) and frequency of dominant genes was greater than recessive
ones. Dominant and recessive genes were not equally distributed among parents as presented by the
H2/4H1 ratio which was different than 0.25 (0.17). According to average degree of dominance
(1.14) superdominance was the case in seed yield expression.
