Abstract: The recent progresses and the main problems in development of breeding materials and breeding methodology of hybrid rice, and its developmental trend were reviewed. The research fields include improvement of current male sterile lines, exploitation of novel male cytoplasm, development of restorer lines with high combining ability, genetic basis of heterosis formation and approaches to breeding super high yielding of hybrids, etc. The research should be focused on application of biotechnology in development of breeding materials and breeding methodology in combination with conventional hybridization technique in the 21st century.
