Abstract

Eramosa is a first early maturing potato cultivar, producing marketable yields comparable to Superior and Jemseg in early harvest trials in Ontario, Canada. Eramosa has produced marketable yields in the range of 15–25 tonnes per hectare in 75–80 days from planting. Tubers are blocky, smooth, semi-flattened with shallow eyes, and have white skin and flesh. Boiling and baking quality is acceptable and specific gravity is similar to Jemseg in early harvest trials (average of 1.070). Field chip quality is acceptable although generally not as light in colour as Superior or Conestoga. Eramosa has good field tolerance to PLRV but it is susceptible to PVY. Eramosa is moderately resistant to scab.

Compendio

Eramosa es el primer cultivar de papa temprana, que produjo rendimientos comparables a los de Superior y Jemseg en ensayos de cosecha temprana en Ontario, Canadá. Eramosa ha producido rendimientos comerciables que varían de 15 a 25 toneladas por hectárea en75 a 80 días después de la siembra. Los tubérculos son macizos, lisos semiaplanados con ojos superficiales y tienen piel y carne blancas. Su calidad en la cocción y en el horneado es aceptable y su gravedad específica en los ensayos de cosecha temprana es similar a la del cultivar Jenseg (promedio de 1,070). La calidad para preparar papa frita a la inglesa es aceptable aunque generalmente de color no tan claro como en el caso de Superior o Conestoga. Eramosa tiene una tolerancia de campo buena al PLRV, pero es susceptible al PVY. Eramosa es moderadamente resistente a la sarna común.
