Abstract:
     A method for selectively culturing three lines of hybrid corn rice with ultra-strong dominance by distant hybridization between paddy rice and corn includes such steps as respective sexual hybridization of the sterile line of hybrid rice with the selfing line and recovery line of corn, and continuous respective backcross of the obtained first hybrid generation with the selfing line and recovery line of corn to obtain the sterile line, maintenance line and recovery line of corn rice, which have ultra-strong dominance, high resistance to stress and high yield.
