Sažetak
The aim of this research work was to assess height, stability and adaptability of oil yield in several Croatian sun- flower hybrids. Trials were conducted on three locations (Osijek, Karanac and Feri anci) during vegetation years
2002 and 2003. In the research work nine experimental and five recognized sunflower hybrids of Agricultural Institute Osijek were included. Four parameters were used for analysis of stability and adaptability: ecovalence, regression coefficient, deviation from regression, Francis and Kannenberg model. The results showed differences between hybrids in oil yield, stability and adaptability. High oil yield, stability and wide adaptability have hybrids: Apolon, Olio, (59A x 5B) x O3 and (253A x 5B) x O3. There were no significant correlations between kernel and oil yield and stability parameters. It indicates possibility for creation of hybrids with high and stabile yield and wide general adaptability. Highly significant correlation between ecovalence and deviation of regression showed that it is possible to assess stability with just one parameter.
