Abstract
Fourteen United States (U.S.) seed potato certification agencies surveyed all U.S. seed potato growing areas for presence of the potato spindle tuber viroid (PSTVd). The survey included general surveillance, which involved searching for the occurrence of PSTVd in state seed potato certification records from 1990 through 2000, and a field survey, which involved testing selected crops for PSTVd infection by nucleic acid dot blot hybridization during 1999 through 2001. No PSTVd incident was documented in any of the state certification records, nor was PSTVd detected in the field surveys. All U.S. seed-growing areas were determined to be free of PSTVd. It is concluded that PSTVd has been eradicated and freedom from potato spindle tuber viroid has been successfully maintained in all of the seed potato growing areas in the United States.
Resumen
Catorce agendas de certificaci⤵ de semilla de papa de los Estados Unidos (EEUU) inspeccionaron todas las áreas de cultivo de papa de EEUU para detectar la presencia del viroide del tubérculo ahusado de la papa (PSTVd). La inspección incluyó una vigilancia general que incluia investigar sobre presencia de PSTVd en los registres de certificación de semilla de papa en el estado desde 1990 hasta fines del 2000 y una inspección de campo en campos seleccionados para detección de PSTVd por medio de la prueba de hibridación local de ácido nucleico durante 1999–2001. No se encontró información documentada de la presencia de PSTVd en ninguno de los registros de certificación del estado, ni tampoco se detectó en las areas de cultivo inspeccionadas. Se determinó que todas las areas de producción de semilla de papa estaban libres de PSTVd. Se concluye que el PSTVd ha sido erradicado y que esta erradicación del viroide del tubérculo ahusado ha sido exitosamente mantenida en todas las areas de producción de semilla de papa de los Estados Unidos.
