Determination of Fruit Quality Properties of Loquat Genotypes Grown In Ordu Province of Turkey

Burhan Ozturk, Ahmet Ozturk


This study was conducted to determine the quality attributes of loquat fruit grown in Ordu province of Turkey, in 2015. In the study, fruit weight, fruit sizes, color characteristics, seed and flesh weight, fruit firmness, pH, SSC and titratable acidity were investigated. The highest (35.52 g and 41.91 mm) and lowest (16.02 g and 31.13 mm) values in terms of fruit weight and fruit length were obtained from Ordu-1 and Ordu- 17 genotypes, respectively. The highest fruit width (41.05 mm) and fruit thickness (39.33 mm) were measured from Ordu-12 genotype. The b * value of the fruit ranged from 46.28 (Ordu-3) to 53.79 (Ordu-8). The seed number ranged from 1.40 (Ordu-24) to 4.80 (Ordu-19). The highest flesh weight (29.04 g) was measured from Ordu-1 genotype. The flesh weight/seed weight ratio varied from 5.04 (Ordu-25) to 2.70 (Ordu-14). Compared the other genotypes, Ordu-1 genotype was higher firmness values than other genotypes. Both the highest SSC value (14.50%) and the lowest acidity value (0.33%) were measured from Ordu-5 genotype. As a results, a wide variation was observed among examined genotypes in terms of quality characteristics.
