Abstract This research was conducted to estimate general and specific
combining abilities for seed yield and certain yield components. Five female
(CMS) lines and five male (restorer) lines were crossed resulting in 25 hybrids
for determination of superior F1 sunflower (Helianthus annuus) hybrids
using line tester
analysis. Based on the performance and gca, the parents CMS 11/2, CMS 47/1,
RHA 68/4, and RHA 72/3 were found to be good general combiners. The crosses
CMS11/2 &× RHA68/4,
CMS11/2 × RHA69/, CMS11/2 × RHA72/3, CMS46/2 × RHA72/3, and CMS47/1 × RHA71/1
gave the highest yields in the experiment, and in addition, CMS11/2 × RHA68/4
showed significant specific combining ability for seed yield. Three other crosses
also revealed positive specific combining ability for other characters.
