In the potato breeding program of the Instituto de Investigaciones Agropecuarias (NIA), 38 cultivars and advanced lines were evaluated for their reaction against G. rostochiensis under laboratory and field conditions using infested soils at La Serena, Chile. Of the 38 materials tested, 16 were resistant in laboratory tests and 13 in field trials. A Kendall TAU B statistical analysis showed a 0.846 value at the 0.01 significance level, indicating a good correlation between both methods.
