Physical and Chemical Characterization of Promising Medlar Genotypes from Carsamba District (Samsun province, Turkey)

Abstract

This study was carried out on the medlar genotypes (Mespilus germanica L.) grown in carsamba dist riot of Samsun province of Turkey in 2017 and 2018. The genotypes physical and chemical traits were examined. Genotypes with fruit weight over 20 g were evaluated based on the two year average values and thus 20 genotypes were included in the study. In the genotypes. the "Weighted Rank it Scale" was made according to the two-year average values of fruit weight, fruit. flesh ratio, soluble solid content and yield potential of the trees. Result indicated that 5 studied genotypes were found to be promising. In the promising genotypes, fruit weight ranged between 28.1-31.6 g. fruit width 37.4-39.8 mm, fruit length 37.3-44.7 mm. fruit flesh ratio 87.9-91.0%, fruit flesh firmness 65.9-89.0%, seed number 4.8-5.1 per fruit. total dry matter 25.9-28.1%, soluble solid content 10.4-15.2%, vitamin C 24.1-36.7 mg 100g(-1). antioxidant activity 22.3-72.0 mmol 100g(-1), fructose content. 6202.7 - 7790.6 mg 100g(-1), malic acid content 1155.8-1495.4 mg 100g(-1) and total phenol content 37.6-71.3 mg 100g(-1)
