Özet:

This study was conducted in 2017 and 2018 in order to identify hopeful genotypes in the population of the Mespilus germanica (Mespilus germanica L.) that grows naturally in the districts of Samsun or Tekkeköy (Turkey). The study selected genotypes with a weight of 15 g or more of fruit. There were 33 genotypes in the study. In the genotypes examined, a reasonable classification method was used to determine the genotypes of the fruit, the fruit meat ratio, the total amount of dry substance, the amount of water-soluble dry substance and the amount of vitamin C, taking into account the hopeful genotypes. In the first year of the study (2017) the fruit weight 15.08-25.44 g, the fruit volume 14.36-24.11 mL, the fruit meat ratio 78.63-92.41, the total amount of dry material 64.20-78.01, the SCHM content 8.4-17.6, the vibrable acid 0.50-0. 98, the amount of vitamin C is 9.60-40 mg 100 g-1; in the second year (2018) the weight of the fruit is 15.13-22.15 g, the volume of the fruit is 15.51-23.05 mL, the proportion of the fruit is 74,03-94.45, the total amount of the dry substance is 67,25-79.24, the content of the SCHM is 6.8-15.9, the vibrable acid is 0.27-1.34, the amount of vitamin C is 7.0-34.0 mg 100 g-1. In the study, the genotypes 4, 25 and 5 that were in the very good group, were determined as hopeful, taking the highest score as a result of the 'Rated Rating'.
