Molecular Characterization of Prunus Cultivars from Romania by Microsatellite Markers

In Romania, Prunus species have great economic and social importance. With the introduction of new cultivars arises need to preserve characterize local germplasm. Thus, a set 24 polymorphic SSRs were selected for overall characterization, including 10 peach, 11 apricot 5 nectarine cultivars. The average number alleles per locus (Na = 1.958), in addition observed (Ho 0.299) expected heterozygosity (He 0.286) lower or comparable those reported similar studies, probably explained by smaller analyzed restricted geographic area. Among 26 genotypes total 101 identified, which 46 55 40 nectarine, respectively. Six from six loci (CPPCT-030, Pchgms-003, Pchgms-004, Pchgms-010, UDP97-401, UDP98-405) common all taxonomic groups. most informative BPPCT-025, Pchgms-021 UDP96-001 peach; BPPCT-001 nectarine; BPPCT-002, Pchgms-020 apricot. Clustering genetic similarity analysis indicated that degree interspecific divergence peach was less than These results will be useful prevent confusion between cultivars, improve breeding strategies benefit management bred Romania.
