Cassava is one of the most important crops for tropical countries. It has a wide range of use such as feed, food and industry purposes. The demand of the growing population encourages increasing crop production. Some of the objectives in breeding for this crop is to produce cassava with high yield, starch and harvest index, low hydrocyanic content, wide adaptation, resistance to pests and diseases and others.
Cassava is a monoecious crop – male and female flowers are separate from each other. Female flowers open first followed by male flowers (1-2 weeks after). Naturally, self- and cross-pollination occur in cassava.
Before doing pollination, check if the condition is favorable. It’s better if the sky is clear and there is low chance of rain for the whole day.
Prepare materials (i.e. glassine bag, uncoated paper clip, marker).
The first step is to determine female flowers that will open that day in the morning. One sure way to know that the female flower will open in the afternoon of the same day is to open one petal of an unopened female flower in the morning and check a drop of nectar on the basal part of the pistil. After selecting the female flower that is about to open in the afternoon, cover it with glassine bag and secure with a clip.
