    Strawberries are cultivated worldwide due to their unique flavor and important bioactive compounds. In this study, the aroma profiles of the 'Sabrina' and 'Osmanli' strawberry cultivars and eight selected hybrid genotypes derived from their cross were investigated using liquid-liquid extraction followed by gas chromatography-mass spectrometry (GC-MS). Both aroma and pomological characteristics were determined and compared among the parental cultivars (Osmanli and Sabrina) and selected genotypes. The total aroma content varied between 4650 mu g/kg in 'Sabrina' variety and 29272 mu g/kg in 'Osmanli' variety. The highest aroma quantity among the hybrids was determined in the genotype '2-10' (18769 mu g/kg). It was observed that the characteristic aroma of the 'Osmanli' variety was due to its high concentrations of esters compounds. As a result of the sensory analysis, the most liked genotype was determined as the genotype '2-10' which contained high amounts of esters. Additionally, unlike the Osmanli variety, this genotype has hermaphroditic flower structure, which is quite important in strawberry cultivation. It also had a 70 % increase in fruit size and a 50 % increase in fruit flesh firmness compared to the 'Osmanli'. This study shows that the breeding studies are crucial in strawberries to increase consumer satisfaction and market value; thus, the continuation of these studies is highly recommended.
