Abstract

This study was carried out to determine the correlation between agronomic traits and seed yield of sunflower cultivars and also to determine the direct and indirect effect of analyzed traits on seed yield. The primary task in sunflower breeding programs is increasing the seed yield and creates new hybrids with high potential for seed and oil yield. Field trials were set up according to randomized block design during two growing seasons (2013 and 2014), on research area of Faculty of Agriculture, "Goce Delchev” University in Ovche Pole locality, Republic of Macedonia. As an experimental material were used 20 sunflower varieties. 1 000 seed weight, length and width of grain, oil content, oleic acid content and seed yield were analyzed. For 1 000 seed weight was obtained highly positive and significant correlation with seed yield and grain width. On the other hand, 1 000 seed weight showed negative and significant correlation with oil content. This trait expressed the biggest positive direct effect on seed yield Key words: sunflower, correlation coefficient, path analysis, agronomic traits
