Abstract
Investigations were carried out with 14 hybrid create in frame of the Agricultural Institute Osijek breeding program. Trials were established as randomize block design in four replication during three years (2002-2004) in region of Osijek. Following traits were analyzed: plant height, 1000 kernel weight, hectolitre mass, grain and oil yield and oil content. Heritability, genetic gain and path analysis correlation between investigated traits and oil yield were evaluated. Investigation hybrids showed significant difference for all analyzed traits. High value heritability for plant height, 1000 kernel weight, hectolitre mass and oil content were evaluated. Heritability for grain and oil yield showed lower value. The biggest genetic gain showed plant height and oil content, and the lowest grain and oil yield. The strongest direct effects to oil yield were assessed for grain yield and oil content.
