Abstract: 

This research was carried out in the coastal region (Demsarkho village of of ​​Lattakia district) and in the laboratories of the Faculty of Agriculture – Tishreen University during 2021 season, for five varieties of Sunflower Helianthus annus L. (variety 90 – variety 19 – variety 9 – local variety – variety 54), which were taken from the General Commission for Scientific Agricultural Research (GCSAR), it was cultivated according to randomized completely block design with three replicates. With the aim of estimating some genetic indicators of growth, productivity  and qualities characteristics to determine the important trait or traits for effective selection to be used in breeding programs. Baladi variety which is a local adapted variety, was characterized by maturity characteristics of maturity (87.97 days), productivity (1699.62 kg / h), oil ratio (42.94%) and weight of 100 seeds (9.45 g). The variety9 has the number of leaves (71.73 leaves) and the number of seeds in the head (447.97 seeds), the length of the plant (92.65 cm). The correlation coefficient between yield and seed weight in the head was positive and highly significant (0.86 **) and this gives the possibility of selection for productivity through the selection of seed weight in the head and can be used as selection index. We propose to continue evaluating (variety9 and local variety) for several years and in more than one geographical location for their distinction between the models studied in many traits.
