<jats:p xml:lang="en">Objective: In this research, evaluations of F1 fall pear hybrids, that obtained from different cross combinations, were made to contribute to our country’s agriculture and gene pool.Material and Methods: 11 hybrids investigated in this research were obtained from the cross combinations that ‘Magness’, ‘Kiefer’, ‘Williams’ and ‘Santa Maria’ cultivars were maternal and, ‘Güz’, ‘Santa Maria’ and ‘Kiefer’ cultivars were used as pollinator parents. Susceptibilities of those hybrids to fire blight disease, pomological and biochemical characteristics were determinated. Besides, sensory parameters were added to the data attained by the measurements, and promising hybrids were detected through the modified weighted ranking method.Results: Fruit width, fruit length, shape index, fruit weight, fruit firmness, soluble solid content, pH, titratable acidity, vitamin C and antioxidant activity characteristics were varied between 53.22 - 84.25 mm, 52.91 - 105.01 mm, 0.95 - 1.62, 86.51 - 317.70 g, 3.32 - 8.41 kg/cm2, %8.77 - 16.53, 3.52 - 4.73, %0.14 - 0.59, 0.53 - 3.17 mg.L-1 and %26.43 - %75.09, respectively. Eight hybrids were evaluated as promising fall cultivars through the modified weighted ranking method.Conclusions: Due to the lack of a definite solution against fire blight, the chemicals used are harmful to human health and organic cultivation is becoming more widespread, the pears with high fruit quality parameters and disease resistant hybrids will come to the fore in the near future, it is thought that the hybrids (2-12-43, 2-15-93, 2-12-47, 1-17-20, 3-36-87, 2-33-32, 2-15-33 and 1-16-130) transferred to the forward observation plot will contribute to pear cultivation by registering in the following period.</jats:p>
