Sentinel (FV8957-10) is a new yellow-fleshed potato cultivar that produces a high yield of attractive round to oval tubers at early harvest. Sentinel is suitable for fresh market use and chip processing. It was selected at the Lethbridge Research Centre of Agriculture and Agri-Food Canada, AB from a cross made at the Potato Research Centre of Agriculture and Agri-Food Canada, NB between breeding clones F72218 and F47024. Sentinel has erect medium-height vines and produces uniform tubers of medium-size with a light buff skin, light yellow flesh and shallow eyes. In multi-date-harvest trials, Sentinel produced similar or higher marketable yield compared to Atlantic and NorValley in southern Alberta. When harvested at 80 days after planting, Sentinel produced similar or greater yield than Superior and Conestoga at test sites across western Canada. Specific gravity of Sentinel was less than Atlantic and Conestoga but higher than NorValley and Superior, whereas chip colour was similar to Atlantic and lighter than NorValley or Superior. Sentinel showed little tendency to slough or to darken after cooking. It showed clear foliar and tuber symptoms when infected with bacterial ring rot. Sentinel is moderately susceptible to verticillium wilt, early blight, fusarium wilt and common scab and susceptible to late blight.

Sentinel (FV8957-10) es una nueva variedad de papa de pulpa amarilla que produce alto rendimiento de tubérculos ovales atractivos en cosecha temprana. Sentinel es deseable para uso en mercado fresco y para proceso de frituras. Se seleccionó en el Centro de Investigación Agrícola Lethbridge de Agri-Food Canadá, AB, de una cruza hecha en el Centro de Investigación de Papa y Agricultura de Agri-food Canadá, NB, entre los clones de mejoramiento F72218 y F47024. Sentinel tiene follaje erecto de media altura y produce tubérculos uniformes de tamaño medio, con una piel marrón claro, pulpa amarilla clara y ojos superficiales. En las cosechas de ensayos multi fechas, Sentinel produjo rendimiento similar o más alto comercial comparada a Atlantic y NorValley en el sur de Alberta. Cuando se cosechó a los 80 días después de la siembra, Sentinel produjo rendimiento similar o mayor que Superior y Conestoga en lugares de prueba por todo el oeste de Canadá. La gravedad específica de Sentinel fue menor que Atlantic y Conestoga, pero más alta que NorValley y Superior, mientras que el color de la hojuela fue similar al de Atlantic y más claro que el de NorValley o Superior. Sentinel mostró ligera tendencia a desprendimiento de la piel o a oscurecimiento después de cocinada. Mostró síntomas claros en follaje y tubérculos cuando se infectó con la pudrición anular bacteriana. Sentinel es moderadamente susceptible al marchitamiento por Verticillium, tizón temprano, marchitez por Fusarium y la roña común, y susceptible al tizón tardío.
