Argentina

Argentina has a diverse potato production system supported by its wide range of climates, soils and growing seasons. Commercial production is concentrated particularly in Buenos Aires Province, with important production also occurring in Córdoba, San Luis, Tucumán, Mendoza, Jujuy, Salta, Santa Fe, Río Negro, Chubut and other provinces. The country can produce potatoes at different times of the year, allowing supplies to reach domestic markets across multiple production windows. The southeastern part of Buenos Aires, particularly around Balcarce, is recognized as the country's principal potato-producing region and has some of its highest yields.

Argentina's potato industry serves both the fresh market and processing sector. The southeastern Buenos Aires production area has favourable soil and climatic conditions for commercial potato cultivation, while irrigation, improved seed quality, fertilizers and crop protection have contributed to productivity improvements. Production is organized into early, semi-early and semi-late crops, with northern provinces contributing to earlier supplies and Buenos Aires, Córdoba, Mendoza, Río Negro and Chubut contributing to later production. This geographical distribution helps maintain potato availability over much of the year.

The country also has an important potato breeding and germplasm conservation program led by the Instituto Nacional de Tecnología Agropecuaria (INTA). INTA's Balcarce program has developed cultivars adapted to Argentine production conditions and different end uses, including fresh consumption and processing. Examples include Huinkul MAG, Serrana INTA, Pampeana INTA, Frital INTA, Calén INTA, Araucana INTA, Keluné INTA and Newen INTA. However, introduced cultivars remain important in commercial production, with Spunta being one of the major foreign varieties grown in Argentina. Argentina also maintains native Andean potato diversity in its northern regions, including varieties such as Tuni, Negra Ojosa, Colorada, Runa, Moradita and Sani.

Potatoes have a long history in Argentina because the country lies within the broader Andean region where cultivated potatoes originated and diversified. Indigenous communities in the Andes cultivated and selected potatoes long before European arrival, and Andean potato diversity extended into northern Argentina. Historical and archaeological research associates the development and spread of potato cultivation in the southern Andes with pre-Columbian societies, while modern research recognizes northern Argentina as part of the natural distribution of Andean potato diversity.

Commercial potato cultivation in Argentina became established during the late 19^th century. A study of the country's potato industry identifies 1872–73 as the beginning of commercial cultivation, initially in the horticultural region around Rosario in Santa Fe Province. During the 20^th century, production expanded geographically and benefited from improved cultivars, irrigation, fertilizers, disease management and higher-quality seed. Argentine potato breeding became particularly important from the 1940s, when INTA began developing locally adapted varieties. In 1948, Huinkul MAG became the first Argentine potato variety registered through the national breeding program, marking an important stage in the development of domestic potato genetics and seed production.
