Abstract

Results of line x tester analysis for 15 sunflower genotypes of the Agricultural Institute Osijek are presented in this paper. Three A lines (cms) and three Rf testers with different oil content level (low, medium, high) in all combinations (nine crosses) were crossed in 2010. In 2011, the lines, testers and their crosses were sown in
field trials at two locations (Karanac and Osijek). The oil content was determined after harvesting, whereas line x tester analysis was conducted based on the obtained results. Variance of lines and testers, which refers to the general combining ability (GCA) was much higher than the variance of line x tester, related to specific combining ability (SCA). It showed on dominant role of the additive component of genetic variance in the inheritance of oil content. Statistically significant differences were not determined between the GCA and SCA effects. The highest values of GCA for oil content had line 2 (medium oil content) and tester 6 (high oil content) at both locations. The largest contribution for oil content had lines (57.81 and 51.28 %) followed by testers (28.88 and 26.27 %) and the lowest accounts for interaction (13.31 and 22.45 %) at both locations
(Karanac and Osijek).
