Sažetak
Within the sunflower breeding program of the Agricultural Institute Osijek, each year is created some few hundred of new hybrid combinations. The best combinations passing through the net of micro and macro trials on different locations in more years. In one of those researches were five registered hybrids (Apolon, Favorit, Olio, Fakir and Orion), and two experimental hybrids ((189A x 5B) x O3 and 219A x O3). The field trials were set up towards a completely randomized block design in 2002 and 2003 year, on the three locations in the Republic of Croatia (Osijek, Karanac and Feričanci). Six traits of the sunflower hybrids were analyzed: plant height, mass of 1000 grains, hectoliter mass, grain yield, oil content and oil yield. Shorter plant height had hybrids Apolon and Favorit. The largest values of 1000 grain mass had hybrids Orion, then Fakir and Olio, and the highest hectoliter mass had Apolon, then Favorit and Olio. By grain yield were pointed out hybrids Fakir, Apolon and 219A x O3, and for oil content Apolon, (189A x 5B) x O3, Favorit and 219A x O3. The largest oil yield had hybrid Apolon (2107 kg/ha), then 219A x O3 (1951 kg/ha), and Fakir (1931 kg/ha). Beside that were analyzed direction and strength of connection among above mentioned traits and oil yield. Among mass of 1000 grains and oil yield as well as hectoliter mass and oil yield were found very low positive correlation. Between plant height and oil yield correlation was medium positive, and only among grain yield and oil yield is established completely positive correlation.
