Kombinacione sposobnosti za visinu biljke i prečnik glave 10 sterilnih A-linija, 3 restorera,
RF linije i njihovih (10x3) F1 hibrida je ispitivano metodom linija x tester. Značajne razlike su
utvrđene između A linija, RF-linija (testeri) i njihovih hibrida. Najveću prosečnu visinu biljke
je imala linija MI-A-57 (198, 17 cm) i hibrid MG-MI-1 x MI-A-57 (239 cm), a najmanju linija PL-
DI-13 (79, 67 cm) i hibrid MG-MI-4 x PL-DI-13 (152, 67 cm). Linija PL-DI-52 (24, 47 cm) i
hibrid MG-MI-4 x MI-A-57 (25, 37 cm) imali su najveći prosečni prečnik glave, dok je …

(Helianthus annuus L.)-Genetika, vol., No. 45, No. 2, 289-296. Combining abilities for plant
height and head diameter of ten sterile A-lines, three restorers-RF lines and their (10x3) F1-
hybrids were examined by line x tester method. Significant differences were found between
A-lines, RF-lines (testers) and their hybrids. The highest mean for plant height had line MIA-
57 (198.17 cm) and hybrid combination MG-MI-1 x MI-A-57 (239 cm), and the lowest mean
had line PL-DI-13 (79.67 cm) and hybrid MG-MI-4 x PL-DI-13 (152.67 cm). Line PL-DI-52 …
