Abstract :Breeding for increase in 1000 seed weight, results in increased seed yield. Therefore it is considered an important criterion in the development of confectionary sunflower hybrids. In this paper, we studied mutual relationships among several quantitative traits on one hand, and between 1000 seed weight on the other. Path coefŞcient analysis was used to separate direct and indirect effects of studied traits on 1000 seed weight, and to identify traits that could be used as selection criteria in sunflower breeding. The research was conducted during three vegetation seasons on 22 NS high-protein two-line confectionary sunflower hybrids, produced within the breeding program at IFVCNS, Novi Sad, Serbia. SigniŞcant and highly signiŞcant correlations were found among the largest number of examined traits. The analysis of simple correlation coefŞcients showed a highly signiŞcant positive correlation between 1000 seed weight and length of seed insert ignore into journalissuearticles values(0.717**);, seed hull ratio insert ignore into journalissuearticles values(0.609**); and signiŞcant positive correlation with thickness of seed insert ignore into journalissuearticles values(0.549*);. A signiŞcant negative interdependence was determined between 1000 seed weight and seed protein content insert ignore into journalissuearticles values(-0.538*);. Path coefŞcient analysis for 1000 seed weight at phenotypic level showed that the length of seed and thickness of seed had a highly signiŞcant direct positive effect on 1000 seed weight insert ignore into journalissuearticles values(DE=0.849**; DE=0.748**);. Width of seed had a strong negative direct effect on 1000 seed weight insert ignore into journalissuearticles values(DE=-387*);. A weak direct negative effect of kernel protein content and seed hull ratio was established, whereas seed protein content had a weak direct positive effect on 1000 seed weight. This indicates that length and thickness of seed have high influence on 1000 seed weight
