Abstract. This study was carried out to determine yield and seed quality of 14 soybean varieties (Blaze, Ataem-7, Bravo, İlksoy, Çetinbey, Nova, Atakişi, Cinsoy, Adasoy, Umut-2002, Türksoy, Arısoy, HA.16-21 and SA-88), conducted with 3 replicates, according to the Randomized Block Experimental Design in the Osmaniye region, Turkey during 2016 growing season. Plant height, seed number per pod, first pod height, number of branches per plant, number of pods per node, number of pods per plant, harvest index, protein content, oil content, hundred seed weight, seed yield and fatty acid composition were the parameters examined. It was found that the controlled parameters values at different soybean varieties ranged as follows: plant height – between 69.47cm (Blaze) and 101.83cm (HA.16-21); number of seeds per pod – between 1.82 units/pod (Adasoy) and 2.21 units/pod (Blaze); first pod height – between 13.10cm (Blaze) and 22.53 cm (Umut-2002); number of branches per plant – between 1.07 units/plant (HA.16-21) and 3.00 units/plant (Nova); number of pods per node – between 2.43 units/node (Umut-2002) and 4.81 units/node (Adasoy); number of pods per plant – between 27.40 units/plant (Umut-2002) and 47.73 units/plant (Adasoy); Harvest Index values – between 43.99% (HA.16-21) and 54.72% (Ataem) – 55.42% (Blaze); protein content – between 36.09% (Nova) and 39.17% (Çetinbey); oil content – between 15.71% (Blaze) and 19.73% (Türksoy) – 19.82% (Arısoy); 100 seed weight – between 12.54g (Arısoy) and 19.18g (Çetinbey); seed yield – between 2470.41 kg/ha (Arısoy) and 3280.03 kg/ha (Adasoy); acid composition values: palmitic acid – from 9.97% (Türksoy) to 11.47% (Çetinbey); stearic acid – from 3.82% (Ataem-7) to 4.38% (Türksoy); oleic acid – from 22.39% (Bravo) to 28.14% (Çetinbey); linoleic acid – from 47.30% (Çetinbey) to 53.26% (Ataem-7) and linolenic acid – from 5.49% (Türksoy) to 6.88% (Bravo). The soybean varieties tested showed different advantages over the individual parameters: in terms of seed yield – Adasoy (3280.03 kg/ha) and Atakişi (3260.60 kg/ha) varieties; in terms of protein content – Çetinbey (39.17%) followed by SA-88 (38.55%) genotype; in terms of oil content – Türksoy variety (19.82%) followed by Arisoy (19.73%) variety; in terms of fatty acid composition the results are very diverse.
