Genetic Characterization of the Norwegian Apple Collection

Commercial fruit production in Norway is located at around latitude 60° north, demanding a careful choice of adapted cultivars. The most comprehensive collection apple genetic resources being kept the Norwegian Apple Collection (NAC) Njøs Fruit and Berry Centre (NJØS). contains 350 accessions was recently genotyped with single nucleotide polymorphism (SNP) array. Curated SNP data were used for assessment structure diversity, pedigree confirmation, core development. In following analysis, we identified several duplicates parent-child relationships. Across geographic regions represented, equally diverse. Different methods analyzing population applied. K-means clustering Bayesian modeling approach prior assumptions revealed five subpopulations associated breeding centers. has distinct low relatedness among accessions; hence, two collections 100 each created. These new will allow breeders researchers to use NAC efficiently. results from this study suggest that could be high importance purposes.
