Abstract

The percentage of starch, dry matter content (DMC) and specific gravity of roots of 28 ten-month old cassava accessions were determined. Regression and correlation made among these factors showed significant correlation between specific gravity and DM (r=0.82); between specific gravity and starch content (r=0.71); and between dry matter and starch content (r=0.99). It appeared that the higher the specific gravity, the higher the starch and the dry matter contents. For rough estimates of the percentage of starch or of dry matter content, specific gravity method would be sufficient. But, for more accurate results, determination of the percentage of root starch based on the percentage DM should be used
