Sažetak
Seed oil content in sunflower is very important trait for seed production and breeding. Aim of this research was to estimate stability of oil content of seven single cross and seven three-way cross hybrids in different environments. The trials were set up on the three locations (Osijek- Eastern Slavonia County, Karanac- Baranja County and Feričanci- Western Slavonia County) during 2002 and 2003 growing seasons. Estimation of stability was conducted by regression coefficient and AMMI model. Oil content was lower in conditions of rainfall deficit and high temperatures in flowering time and during seed maturity process. Three-way cross hybrids had slightly higher oil content. According to regression coefficient, most of the hybrids were stable. According to AMMI model, the most stable hybrids were experimental hybrids OS-H-103 S, OS-H-219 S, OS-H-259 S, OS-H-59 T and OS-H-189 T. Hybrid Apolon had the highest oil content and it was adapted to high yielding environments. Hybrid Fakir was according to, both regression coefficient and AMMI model, adapted to low yielding environments.
