Abstract

Phenotypic and molecular characterization of apple (Malus × domestica Borkh) genetic resources in Greece

Highlights

  • Malus × domestica Borkh. is the crop with the highest economic impact of the Rosaceae family (FAO, 2015) and among the most important fruit crops of temperate zones

  • This study shows the results of an investigation on the morphology and Natural Environment – Dept. of Forest Genetics and Tree the genetic diversity for 19 apple cultivars, which are preserved in an ex situ collection in Naous-Breeding, University Campus – 54124 – Thessaloniki

  • Approach and the genetic distance clustering approach grouped the apple cultivars according to their type

Introduction

Malus × domestica Borkh. (apple) is the crop with the highest economic impact of the Rosaceae family (FAO, 2015) and among the most important fruit crops of temperate zones. (apple) is the crop with the highest economic impact of the Rosaceae family (FAO, 2015) and among the most important fruit crops of temperate zones. The use of molecular markers to identify the genetic makeup of a species and a variety has become one of the most important means to characterize and manage germplasm collections of fruit species. Microsatellites, or SSRs, are the DNA markers of choice to uncover the genetic diversity between and within fruit species (Gupta et al, 1996), due to their high polymorphism level, abundance and co-dominant inheritance and reproducibility, as well as relative easiness of analysis (Madesis et al., 2013). Many authors used this technique to determine the genetic diversity in order to identify duplicates and genetic relationships within and between
