Summary and Conclusions

The specific gravity of three concentric zones within tubers of 19 potato varieties was determined over the two-year period 1956–1957. During this study, a clear pattern emerged. In varieties where specific gravity of the entire tuber was high there was a large difference in spcific gravity between zone three (pith) and the two outer zones. In varieties with low specific gravity this difference was comparatively small. There was generally little difference in specific gravity between zones one and two. Specific gravity of zone three was relatively uniform between varieties.
