Abstract

Seed potato certification programs include field inspections to measure variety mix during the growing season. The ability of seed potato growers to meet variety mix tolerances could be an indicator of the likelihood of future GM potato growers to meet similar tolerances. We collected variety mix data from eight states for the 2008 and 2009 crops. The portion of lots that had variety mix was 3.5% in 2008 and 3.3% in 2009. We estimate that on a tuber basis, variety mix was 0.04% in 2008 and 0.024% in 2009. Those levels of mix are well within Japan’s tolerance of 5% GM mix for imported non-GM products.

Resumen

Los programas de certificación de semilla de papa incluyen inspecciones de campo para medir la mezcla de variedades durante el ciclo del cultivo. La habilidad de los productores de semilla de papa para cumplir la tolerancia de la mezcla de variedades pudiera ser un indicador de la probabilidad de futuros productores de papa GM para ajustarse a tolerancias similares. Colectamos datos de mezcla de variedades de ocho Estados de los cultivos de 2008 y 2009. La porción de lotes que tenían mezcla de variedades fue de 3.5% en 2008 y 3,3% en 2009. Estimamos que con base a tubérculos la mezcla de variedades fue de 0.04% en 2008 y 0.024% en 2009. Esos niveles de mezcla están muy dentro de la tolerancia de Japón de 5% de mezcla de GM en productos importados no GM.
