Genetic Characterization of a Plum Landrace Collection from La Palma, Canary Islands

A plum collection located in the island of La Palma, Canary Islands, composed twenty-nine European and Japanese plums was analyzed using nine simple sequence repeat (SSR) highly polymorphic loci. First, a cytometry flow analysis performed to determine ploidy level. Sixteen accessions turned out diploid thirteen hexaploid. According morphological characteristics, fourteen sixteen were assigned Prunus salicina, two P. cerasifera. All hexaploid domestica. The 29 compared SSR markers with twenty-two domestica maintained at CITA germplasm Zaragoza, Aragón, Spain. principal component (PCA) clustering approach grouped according species geographical location, while some synonyms homonyms found within Palma accessions. components explained 80.3% (67.3% 13%, respectively) total variance. tree generated UPGMA hierarchical Bruvo distance main clusters level assignment. STRUCTURE clearly differentiated from those collection. results obtained could be used for management conservation purposes this valuable local germplasm.
