A lysozyme gene resistant to rice blast from the donor D2-1-2, a transgenic japonica rice line of Zhonghua 9, was transferred into the sterile line Pei'ai 64S(PA64S) and restorer line 9311 of the hybrid Liangyoupeijiu, and the restorer line Minghui 63 (MH63) of Shanyou 63 by successive backcrosslng. PCR analysis confirmed that foreign lysozyme gene was segregated with the ratio of 1 ; 1 in backcross generations of Ba 9311, B3 MH63 and Be PA64S, and with the ratio of 3 : 1 in inbred generations of B2 F2 9311, B2 F2 MH63 and B1 F2 PA64S, in...
