Ecuadorian potato landraces: Traditional names and genetic identity

Ecuadorian potato landraces (Solarium tuberosum L.) are an important genetic resource, but they have been poorly described. Simple Sequence Repeats (SSR) markers were applied to 152 landraces to assess the genetic diversity of potatoes collected in three areas of high diversity: the Carchi, Chimbora...

Las papas nativas ecuatorianas (Solarum tuberosum L.) son recursos genéticos importantes, pero se han descrito pobremente. Con el fin de estudiar la diversidad genética de estas papas se aplicaron marcadores de Secuencias Simple Repetidas (SSR) en 152 papas nativas colectadas en tres áreas de alta diversidad: provincias de Carchi, Chimborazo y Loja. Estos marcadores SSR fueron previamente aplicados en el genotipeo de más de 800 variedades de papas europeas. El número de alelos y valores del Contenido Informativo del Polimorfismo (PIC) de los marcadores fueron comparables entre las europeas y nuestro estudio; sin embargo, el traslape de alelos fue pequeño. La relación entre nombres locales de las papas nativas y la identidad genética, basada en datos SSR, mostró que había algunas papas nativas con diferentes nombres que tenían perfiles moleculares idénticos. Dicha relación también mostró que papas nativas con nombres idénticos, pero obvias diferencias en la morfología del tubérculo, fueron casi siempre diferentes genéticamente. No hubo un agrupamiento claro del material colectado de acuerdo con las regiones investigadas, lo que sugiere un movimiento extensivo de semillas de papas a lo largo de Ecuador. 2018-02-01T17:16:12Z 2018-02-01T17:16:12Z 2017 Revista Artículo 0187-7380 *EC-INIAP-BEESC-MGC.
