Intersubspecies hybrid rice have strong hetero-sis but low seed-setting rate. Researches haveshowed that most of unfilled and partially-filled grains occurred in late-floweringspikelets on the base of a panicle, which usual-ly maintain quiescent state for a period afterflowering. It was demonstrated that the rea-son for this was the “apical dominance” ratherthan the shortage of nutrients. Filling of the
