Abstract
Breeding for impact resistance in potato is common at the end of a bre eding scheme, where there is no more variability for it. The purpose o f this study was to propose an objective progeny test using a pendulum and single-year data. Data were recorded over a 5-year period using 2 75 progenies, organized in small factorial and hierarchical designs. T he variability of response of the additive variance made it impossible to generalize parental choice. However, once the crosses were made, t he high degree of variability among the progenies and the high level o f broad-sense heritability in every case suggest that selection can be carried out efficiently using single-year data.
