Breeding and Genetics Barandalla, Leire [2], Ríos Mesa, Domingo José [1], Ruiz de Galarreta, José Ignacio [2], Ritter, Enrique [2]. Characterization of potato varieties from Canary Islands by microsatellite markers. A total of 57 accessions from Canary Islands (Spain) were collected and characterized using 19 SSR molecular markers. The fifty seven accessions belonged to Solanum tuberosum subsp. tuberosum, S. tuberosum subsp. andigena and S. x chaucha species. DNA extraction was carried out using the DNAeasy Plant Mini kit from Quiagen (Valencia, USA). Nineteen SSRs were used and amplification products were separated on polyacrylamide gels with a LI-COR 4200-S1 DNA Sequencer. The dendogram showed that Moras and Brasileña accessions make up the first group. The second and the third groups were formed by the Negra and Cecilia, respectively. The fourth group was formed by the Coloradas cultivars and some accessions included in the S. tuberosum subsp. andigena. The fifth group comprised two entries from La Palma and the sixth group was formed by the Negras and Conejera accessions. The seventh group comprised the Corraleras and the eighth was the most heterogeneous group. The ninth group was formed by one accession called Moruna. The next group enclosed the cultivars Palmeras and Marcialas, and the eleventh group comprised the entries Pelucas. This study will contribute to clarify the relationships between the different accessions of the Canary Islands Such collections of related accessions of the Andes are available at CIP (Peru). A comparison of SSR patterns could be helpful to identify possible origins of these cultivars from Canary Islands or help to analyse adaptive evolution in different habitats.
