Early-morning flowering (EMF) helps rice plants to escape heat stress damage under field conditions. EMF traits and spikelet sterility were estimated from indica cultivars originating from 13 tropical and 20 subtropical countries. None of the tested 289 cultivars had the EMF trait. EMF trait introgressed into popular rice cultivar showed high environmental stability.
