Abstract: A procedure for the development of a male sterile rice,Minke 104S,was established.The low-temperature-sensitive,genic sterile SE152S was used as the main parents.The lower generations of the segregated population obtained through crossing and backcrossing were planted in high altitude Huyuan Village in Shaxian County,where the average day-length was long and temperature low.The sterile lines were generation-added in Hainan Province and Shaxian County to obtain Minke104S with stable infertility.The breeding procedures are presented for possible breeding applications on the development of photo/thermo-sensitive,male sterile rice lines.
