THE FUNCTION OF CYANOGENESIS IN CASSAVA
Several methods are proposed for gathering information on the function of cyanogenesis in cassava; these include studying existing data and devising new experiments. In new experiments, the following points should be considered:
- Variation in cyanogenesis, herbivore resistance and yield should be studied in crosses made specifically for the purpose.
- Cyanoglucoside concentration and -glucosidase activity should be measured regularly in both leaves and starchy roots, during the course of the experiments.
- Herbivore activity should be controlled, and at least two different levels of herbivory should be applied.
In the absence of data it is currently impossible to give guide-lines for breeding objectives regarding cyanogenesis.
