Conteúdo: 	This study aimed to calculate correlation coefficients of  potato tuber traits between the seedling generation (SG) and the first field generation (FFG) and their implications on selection. The work was carried out at Embrapa Temperate Agriculture, Pelotas-RS, Brazil. Three pot sizes in SG and three plot sizes were tested, using ten progenies. The experiment was arranged in a split-plot design with three replications. In both gerenarions, tubers of each plant were evaluated for yield, number, skin texture, stolon insertion depth, eye depth, eyebrown prominence, shpae, flatness, curvature, pointed ends and appearance. Coefficients were significant for yield, number, shape, pointed ends and skin texture, but correlations was strong only for yield fo L pot x L plot, moderate for M pot x M plot and S pot x Splot; for number moderate for L pot x L plot, while for other pot and plot sizes they were weak; for shape, moderate for L pot x L plot, and M pot x M plot; and for other traits, coefficients were low or not significant. These results suggest that in SG, using L pots, selection could be applied for yield at strong intensity, and for number and shape at moderate intensity; while using M pots, selection could be applied for yield, number and shape, but at moderate intensity; and using S pots, selection could also be applied at moderate intensity, but only for yield.
