The most important criterion for introducing new confectionary hybrids into production is high protein yield. Breeding for increase of kernel protein content results in increased protein yield. Path coefficient analysis was performed to separate direct and indirect effects of studied traits on seed kernel protein content, and to identify traits which 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. Strong and very strong correlations were found among the largest number of examined traits. Based on the analysis of simple correlation coefficients, strong negative correlation was determined between kernel protein content and kernel ratio (-0.516*). A weak negative interdependence was determined between head diameter, seed protein content, and kernel protein content. Positive but weak correlatio...n was determined between kernel protein content and thickness of seed, length of seed, width of seed, and 1000 seed weight.
