摘　　要：Dear Editors,Heterosis utilization is an effective way to improve crop yield.Hybrid rice typically out-yield inbred rice varieties by 10%and show better stress resistance,and they have been widely adopted in Asian countries since the 1980s(Cheng et al.,2007).To produce rice F1 hybrid seeds(HSDs),male sterile lines(MSLs)are grown side by side with restorer lines(RLs)in order to receive the RL pollen.This seed production system faces challenges in maintaining the seed purity of the HSDs owing to the physical proximity of MSL and RL plants in the field.Traditionally,MSLs and RLs are planted in alternate rows to enable physical separation of seeds during harvesting.
