Spt transformation event of rice and detection method thereof

Provided is a transgenic rice plant containing a seed production technical event and the plant genome DNA flanking a transgenic sequence. Additionally provided is the fertility recovery of a homozygous recessive genic male sterile rice plant, and uses of said homozygous recessive genic male sterile rice plant. Specifically provided are rice transformation events SPT-7R-949D and SPT-7R-1425D, a primer pair, a probe pair or a reagent kit for detecting and identifying said rice transformation events, a method for using said primer pair, probe pair or reagent kit to detect a transformed plant and offspring thereof, including a construct, a tissue, an organ, a plant or a seed of a plant related to the rice transformation event, and also a method for constructing male sterile line of rice, a method for restoring the male fertility of a sterile rice plant, and a method for preparing hybrid rice.
