摘　　要：In order to improve the panicle extrusion of photo- and thermo-sensitive sterile line ‘Pei＇ai 64S＇ by using elongated uppermost internode （eul） gene of the wide compatibility rice mutant ‘02428h＇, a new photo- and thermo-sensitive sterile line ‘P8hS＇ characterized with elongated uppermost internode was developed by transferring the eui gene into Pei＇ai 64S through three successive backcrossing, Compared with Pei＇ai 64S, the plant height of P8hS was 35.6 cm higher resulted from the elongation of the uppermost and the second internodes from the top. The panicle extrusion of Pei＇ai 64S was completely improved and positive effects were found on the main economic characters of P8hS and its hybrids by introducing euigene into Pei＇ai 64S.In order to improve the panicle extrusion of photo- and thermo-sensitive sterile line ‘Pei＇ai 64S＇ by using elongated uppermost internode （eul） gene of the wide compatibility rice mutant ‘02428h＇, a new photo- and thermo-sensitive sterile line ‘P8hS＇ characterized with elongated uppermost internode was developed by transferring the eui gene into Pei＇ai 64S through three successive backcrossing, Compared with Pei＇ai 64S, the plant height of P8hS was 35.6 cm higher resulted from the elongation of the uppermost and the second internodes from the top.
