Abstract
Jemseg is an early sizing variety of early maturity. It has outyielded the variety Warba for total and marketable yield when dug at 80 days from planting. It has moderate resistance to common scab, is immune to virus X and has high resistance to virus Y, plus resistance to virus S.
Jemseg was originated at Fredericton, New Brunswick, and is a product of the potato breeding program of Agriculture Canada. The variety has been under test in New Brunswick for 10 years as seedling F67072. It has also been tested extensively in the Maritime Provinces and throughout Canada through the facilities of regional and national evaluation trials.
Jemseg was selected from a progeny of a cross between the variety Sable and a Fredericton seedling F55069. Sable is an early variety developed at Fredericton. F55069 is a Fredericton seedling bred for X immunity and scab resistance. Jemseg was first grown in the field in 1967. The pedigree follows:
Resumen
Jemseg es una variedad de madurez precoz y cuyos tubérculos alcanzan un tamãno grande en una etapa temprana del ciclo vegetativo. En cosechas realizadas a los 80 días de la siembra, Jemseg superó a la variedad Warba en rendimientos total y comercializable. Tiene una resistencia moderada a la sarna común, es inmune al virus X y tiene alta resistencia al virus Y además de su resistencia al virus S.
Jemseg fué obtenida en Fredericton, New Brunswick por el programa canadiense de mejoramiento de papa. La variedad ha estado sometida durante 10 años a pruebas en New Brunswick con la denominación de seedling “F67072”. Ha sido también extensivamente probada en las provincias marítimas y a través de Canadá, contando con las facilidades de los ensayos de evaluaciones regionales y nacionales.
Jemseg fué seleccionada de una progenie del cruce entre la variedad Sable y el “seedling” de Fredericton F55069. Sable es una variedad precoz desarrollada en Fredericton. F55069 es un seedling de Fredericton que combina inmunidad a virus X y resistencia a sarna común. Jemseg fué sembrada por primera vez en el campo en 1967.
