Studied in this paper was the effect of PET1 and ANN5 cytoplasms on plant height, hectoliter mass, seed kernel content, and seed husk content of four inbred sunflower lines as well as of the crosses of the lines' sterile forms with three restorers. In the crosses, heterosis relative to the parental mean (H1) and heterosis relative to the better parent (H2) were calculated. PET1 cytoplasm affected plant height in lines L-1, L-10, and L-14, hectoliter mass in all of the lines, and on seed husk content in lines L-11 and L-10. ANN5 cytoplasm, for its part, influenced plant height in lines L-10, L-14, and L-19 and on hectoliter mass in lines L-1, L-10, and L-14. PET1 cytoplasm caused no significant increase in the seed kernel content of the lines, and ANN5 cytoplasm did not significantly increase the lines' kernel and husk contents, either. The said cytoplasms' effects on the expression of the quantitative traits under study were not equally significant in all of the crosses.
