Potato was introduced in Montenegro in the middle of the eighteenth century. Since then it has become the most important crop in plant production. During the period between 2008 and 2010 a total of 52 potato accessions was collected across Montenegro and stored in a national gene bank. In the study reported here 23 accessions from the collection were examined using microsatellite (also known as simple sequence repeats or SSRs) molecular markers with the aim to explore genetic diversity and redundancy within the germplasm. The accessions were selected on the basis of preliminary characterization of all 52 accessions for 11 lightsprout traits. Molecular characterization of 23 accessions by 12 SSR markers was carried out at SASA (Science and Advice for Scottish Agriculture) that manages a database of more than 3000 genetic profiles of potato from Europe and abroad. Comparison of SSR genetic profiles of Montenegrin collection against the existing SASA database allowed us to test the authenticity of the Montenegrin accessions. Out of the 23 accessions examined, 13 showed distinct genetic profiles of which seven showed perfect matching with known cultivars, two profiles showed strong similarity to another two cultivars, and four profiles were found unique with regards to the SASA database. Application of microsatellite markers in this study provided valuable information on the extent of genetic diversity residing within Montenegrin potato germplasm; it gave clear indications of the scale of redundancy within the collection; and helped clarify the identity of the accessions. Four accessions within the collection might incorporate unique variation and will be subjected to further agronomical examinations to assess their potential for breeding purposes.

La papa se introdujo a Montenegro a mediados del siglo 18. Desde entonces, se ha convertido en el cultivo más importante en la producción vegetal. Durante el período comprendido entre 2008 y 2010, se colectó un total de 52 accesiones a lo largo de Montenegro y se almacenó en un banco nacional de germoplasma. En nuestro estudio aquí reportado, se examinaron 23 accesiones de la colección usando los marcadores moleculares microsatélites (también conocidos como repeticiones de secuencias simples o SSRs), con el propósito de explorar la diversidad genética y redundancia dentro del germoplasma. Se seleccionaron las accesiones con base en caracterización preliminar de las 52 colectas para 11 características sobresalientes. La caracterización molecular de las 23 accesiones con 12 marcadores SSR se desarrolló en SASA (Science and Advice for Scottish Agriculture), que maneja una base de datos de más de 3000 perfiles genéticos de papa de Europa y otros lugares. La comparación de los perfiles genéticos SSR de la colección Montenegrina contra la base de datos existente de SASA nos permitió probar la autenticidad de las accesiones de Montenegro. De las 23 colectas examinadas, 13 mostraron perfiles genéticos distintos, de los cuales siete mostraron coincidencia perfecta con variedades conocidas, dos perfiles mostraron fuerte similitud a otras dos variedades, y cuatro perfiles fueron únicos en relación a la base de datos de SASA. La aplicación de los marcadores microsatélites en este estudio contribuyó con información valiosa en cuanto a la diversidad genética residente en el germoplasma Montenegrino de papa; dio indicaciones claras de la escala de redundancia dentro de la colección, y ayudó a clarificar la identidad de las accesiones. Cuatro de éstas pudieran incorporar variación única y será sujeta a análisis agronómicos posteriores para evaluar su potencial con propósitos de mejoramiento.
