Identification of Citruses from Montenegro Based on Microsatellite Clustering Analyses

Abstract

AbstractA set of 32 citrus genotypes were selected from Montenegro collection and analyzed by the use of 11 microsatellite markers. Analyses harvested 72 different alleles having 6.5 alleles per locus and discovered presence of 23 unique genotypes. Distance analysis and model-based clustering revealed both the presence of 4 groups: satsuma (Citrus unshiu Marc.) mandarins, clementine (Citrus reticulata) mandarins, sweet oranges (Citrus × sinensis) and lemons (Citrus limon). Distance based clustering enabled the differentiation between red and yellow flashed fruits due to the presence of allele 158 on the locus AC01 in blood oranges. Specific goal of the study was to clarify the identity of 3 local citrus genotypes through observing their relationships within well-established clustering with the rest of genotypes being known citruses. Local orange ‘Domaca Pomorandza’ grouped with other sweet oranges but could not be differentiated from ‘Navelina’ and ‘Skagss Bonanza Navel’. ‘Gorka Pomorandza’ had unique fingerprint and showed to be sour orange. Local lemon ‘Mjesecar’ showed to may be belonging to the Femminello group of lemons. Genetic characterization of local genotypes will serve for cultivar recognition and their future improvement.
