Genetic Identity and Diversity of Apple Accessions within a Candidate Collection for the Norwegian National Clonal Germplasm Repository

In order to best conserve, as well utilize, traditional apple germplasm in Norway, an heritage cultivar collection was established Ullensvang, western which aims become the National Clonal Germplasm Repository. The establishment of preceded by a molecular study that aimed genotype large number accessions maintained various ex situ sites and south-eastern using rather small set eight SSR markers. However limited, marker managed identify synonyms, homonyms, duplicates within among investigated collections. this study, 171 from Ullensvang were genotyped 20 different Approximately half have been previously markers, enabling assessment whether use larger would yield more accurate characterization. Based on obtained data, determined hold key part overall genetic diversity Norwegian germplasm. Furthermore, twelve additional markers able differentiate several groups originally thought be provide detailed insight into structure
