Analyses are based on data collected from field experiments carried out in the years 1990-92 on podzolic soil derived from light loamy sand. The calculation of correlation and regression coefficients allowed analysing the effect of some climatic factors on the contents of dry mass, starch, sum of sugars in tubers as well as vitamin C, in tubers of 37 potato varieties. It was found that raising of temperature in the period of July-August increased the content of dry mass and sum of sugars in tubers, and at the same time decreased the content of starch and vitamin C
