Mudurnu-Bolu’daki Elma Genotiplerinin Morfolojik Özellikleri

Abstract

This research was carried out in the Mudurnu district of Bolu province to determine the morphological and chemical properties of 17 apple genotypes. Fruit and seed properties and soluble solids content, pH, titratable acidity, and fruit peel color (L*, a*, b*, Chroma*, and hueº) were examined. Descriptive statistical analysis, principal component analysis, and hierarchical clustering analyses were used to determine the morphological and chemical properties of the genotypes. Fruit weights were determined as 29.06-126.3 g, fruit diameter as 30.55-74 mm, fruit flesh firmness as 2.4-7 kg/cm², soluble solids content as 12-18.21%, and pH as 2.93-5.3 in the examined genotypes. It was determined that G3 and G19 genotypes differed from the other genotypes regarding the examined properties. The genetic diversity identified in this study provides a valuable foundation for breeding programs aimed at developing new apple cultivars that are adapted to regional conditions and meet market demands. Particularly, the distinct genotypes such as G3 and G19 are significant due to their potential use as parents in future selection studies or hybridization programs.
