Summary
The possibilities of selecting individual seedlings and seedling populations for dry matter content and chip colour were examined. Tuber glucose content as measured with Reflocheck Glucose test strips was strongly correlated with the colour of the chips, but Gluko-Test strips were less reliable.
Glasshouse and field determinations of both the dry matter content and the glucose content of the seedling populations were closely related. Therefore it should be possible to select populations for both characters on the basis of the population performance in the glasshouse.
Individual seedlings could be reliably selected for dry matter content, but such selection should not be rigorous. Individual seedling selection for chip colour is not recommended.
