However, due to the sudden change of the external conditions, the flowering will still be missed. In order to prevent this problem from occurring, flowering forecast can be carried out, that is, 3 to 5 representative points are selected in the farming system, and 2 to 3 representative parental and parental lines are taken at each point.
