The Inter-genebank potato database and the dimensions of available wild potato germplasm

Article

Abstract

The Association of Potato Inter-genebank Collaborators (APIC) constructed a database of all wild potato holdings of the most important potato genebanks in Europe, the United States, Peru, and Argentina. The Inter-genebank Potato Database (IPD) now contains data of 11,819 wild potato accessions conserved in seven potato genebanks. The collector’s number is the key identifier used to merge all databases into the IPD. A total of 7,112 different wild potato accessions were identified, which comprise 5,306 accessions with known collector’s numbers. The IPD passport database showed that almost 30% of accessions held in APIC genebanks are from Argentina, a country that comprises less species diversity than Peru and Bolivia. These latter countries are represented by 24% and 20% of accessions, respectively. APIC genebanks maintain 188Solarium taxa out of more than 230 recognized by the latest comprehensive treatment of potatoes(Solarium sect.Petota) by Hawkes (1990). About 60% of the accessions comprise only 20 taxa represented by 785 to 92 accessions each. Conversely, 2% of the accessions comprise 72 taxa and are represented by five or fewer accessions each. About 70 taxa are not available in any genebank. The IPD evaluation database comprises 5,603 records with data from more than 33,000 evaluations of wild potato accessions. Fifty-five traits are summarized, including the reactions of the accessions to 12 pathotypes or races or strains of 12 fungi, four bacteria, 12 viruses, one viroid, 13 nematodes, and seven insects; response to heat and cold stress; and content of dry matter, starch, vitamin C, amylase, reducing sugars, and glycoalkaloids. About 30% of the wild potato populations screened showed various levels of resistance to most of the diseases and pests evaluated. The IPD database is available on the Internet at www.potgenebank.org.

Resumen

La Associatión para la Colaboración entre Bancos Genéticos de Papa (APIC) ha ensamblado una base de datos de todas las especies silvestres de papa conservada en los bancos genéticos más importantes de Europa, E.E.U.U., Perú y Argentina. La Base de Datos de Papa de los Banco Genéticos (IPD) contiene datos de 11,819 entradas de papas silvestres conservada en siete bancos genéticos. Se utilizó el número de colector como el identificador clave para unir todas las bases de datos de cada banco genético. Se identificó un total de 7,112 entradas diferentes de papas silvestres que comprenden 5,306 entradas con número de colector conocido. La base de datos IPD muestra que las papas silvestres de la Argentina representan casi el 30% de las entradas conservadas en los bancos genéticos de la APIC. Argentina tiene menos diversidad de especies que Perú y Bolivia, que están representados por 24% y 20% de entradas respectivamente. Los bancos genéticos en APIC conservan 188 especies silvestres de papa de más de 230 que son reconocidas por Hawkes (1990). Alrededor de un 60% de las entradas en APIC comprenden solamente 20 especies representadas por 785 a 92 entradas cada una. En el otro extremo, 2% de las entradas comprenden 72 especies que están representadas por 5 o menos entradas cada una. Cerca de 70 especies de papas silvestres no están disponibles en los bancos genáticos. La base de datos IPD con datos de evaluación de especies silvestres comprenden 5,603 registros con más de 33,000 evaluaciones. El número de características evaluadas es de 55 incluyendo las reacciones a patotipos, razas o strains de 12 hongos, 4 bacterias, 12 virus, 1 viroide, 13 nematodes, y 7 insectos; reacción al calor y la sequía, y contenido de materia seca, almidón, vitamina C, amilasa, azúcares reductores y glicoalkaloides. Alrededor del 30% de las poblaciones de especies silvestres tamizadas mostraron varios niveles de resistencia a la mayoria de enfermedades y plagas evaluadas. Esta base de datos esta disponible en Internet www.potgenebank.org.
