摘要
A breeding method of a polyploid rice photo-thermo-sensitive genetic male sterile line includes determining a diploid rice line with photo-thermo-sensitive genetic male sterility or PMeS characteristic as a parent; carrying out hybridization on a diploid photo-thermo-sensitive genetic male sterile line and a diploid PMeS gene line, carrying out doubling culture on a young ear of a hybrid plant into a hybrid tetraploid; back-crossing the hybrid tetraploid with a tetraploid photo-thermo-sensitive genetic male sterile line; selecting a tetraploid male sterile plants from the back-crossed progeny, self-crossing during a low-temperature and short-day fertile period, and then carrying out composite hybridization with another tetraploid rice line having PMeS gene; selecting tetraploid male sterile plants, and detecting the stability of tetraploid male sterile plants after multiple generations of continuous self-crossing; and determining the stable and consistent tetraploid rice sterile line as the polyploid rice photo-thermo-sensitive genetic male sterile line, named as PSXXX.
