Marcy: A chipping variety with resistance to common scab and the golden nematode

Abstract

‘Marcy’ is a white-skinned, white-fleshed potato cultivar notable for its high yield, good chip color, and resistance to common scab and race Ro1 of the golden cyst nematode. It was selected from a cross made at Cornell University in 1990 between ‘Atlantic’ and Q155-3. Full-season marketable yields of Marcy have averaged 15% to 20% greater than Atlantic in 83 trials across New York, Maine, and Pennsylvania. Specific gravity of Marcy has averaged 0.008 less than Atlantic. Chip color out of 7 C storage in New York has been similar to ‘Pike’, but not as light as ‘Snowden’. Marcy tubers have an attractive oval shape, shallow eyes, and highly textured skin. Marcy was jointly released by the New York and Pennsylvania Agricultural Experiment Stations in 2002.

Resumen

‘Marcy’ es un cultivar de papa de piel y pulpa blancas, notable por su alto rendimiento, buen color de hojuelas, resistente a la sarna común y a la raza Ro1 del nematodo dorado del quiste. Fue seleccionado de un cruzamiento entre ‘Atlantic’ y Q155-3 hecho en la Universidad de Cornell en 1990. En temporada plena, los rendimientos comerciables de Marcy han tenido un promedio de 15–20% más que Atlantic en 83 ensayos en Nueva York, Maine y Pennsylvania. El peso específico de Marcy ha promediado 0.008% menos que Atlantic. El color de las hojuelas fuera del almacenamiento a 7 C en Nueva York, ha sido similar a ‘Pike’ pero no tan claro como ‘Snowden’. Los tubérculos de Marcy tienen una atractiva forma oval, ojos superficiales y piel de excelente textura. Marcy fue liberada por las Estaciones Experimentales de Nueva York y Pennsylvania conjuntamente en el año 2002.
