Method for producing Guangliangyou No.1 hybrid rice seeds

The invention belongs to the field of heterosis utilization, and particularly discloses a method for producing Guangliangyou No.1 hybrid rice seeds. The Guangliangyou No.1 hybrid rice seeds are new three-line early rice compositions produced by hybridizing a cytoplasmic male sterile line Guang 8S and a restorer line R1, wherein the female parent Guang 8S is the high-yield, high-quality and high-resistance cytoplasmic male sterile line bred by an expert Yang Zhenyu; and the male parent restorer line R1 is an inbred line. The hybrid seeds have the characteristics of high yield, stable production, high disease resistance and high biological yield.
