Model for prediction of heat-induced spikelet sterility in rice worldwide

We have demonstrated for the first time in the world using an international monitoring network (MINCERnet) of micrometeorology in rice paddy fields, that heat-induced spikelet sterility (HISS) in paddy fields under various climates can be uniformly evaluated by using the rice panicle temperature during flowering time instead of air temperature as an indicator. By utilizing this evaluation method, it will be possible to improve the accuracy of predictions of HISS around the world and take appropriate measures against HISS.
