Abstract

The production of Andean potato (Solanum tuberosum spp. andigena) is an important resource in the Andes region of northern Argentina. Roots of this plant, with origin in the department of Iruya (Province of Salta), have been recently found attacked by cysts of the genus Globodera. Morphological and morphometric studies at different life stages, as well as the sequence analysis of the internal transcribed spacer (ITS) of the ribosomal DNA showed that the population considered belongs to the species G. pallida. This nematode is one of the main pathogens of potato crops in the world. Although the European and Mediterranean Plant Protection Organization (EPPO) indicated a restricted distribution of the nematode in the country, there is no accurate reference to confirm its presence. Hence, this work is the first record of the nematode in continental Argentina. Complementary studies should be conducted to evaluate its distribution in the Andean region and its effect on potato production
