用１６个玉米自交系同Ｃ型、Ｙ型和ＹⅡ型雄性不育系测交、回交，以了解不育系的恢保关系；将Ｃ型不育系测交Ｆ１中的可育株自交，同时与Ｃ型不育系回交。以分析Ｃ型不育系恢复性的遗传行为。结果表明，５００３、３３０、白３３０、０３５－６、木６－１１等５个自交系为Ｃ型不育系的恢复系，３２－２、贞３６７、ｉ－１等３个自交系保持Ｃ型不育系的不育性；ＴＲ３７０２、７７－１、承１０－９、５００３、４４９、交５１等６个自交系保持Ｙ型不育系的不育性；贞３６７、１０７－１为ＹⅡ型不育系的恢复系，ＴＲ３７０２、青Ｃ２、０３５－６、３３０、５００３等５个自交系保持ＹⅡ型不育系的不育性。３２－２对Ｃ型、承１０－９对Ｙ型、５００３对Ｙ型和ＹⅡ型的回交Ｆ１全部不育，可用连续回交法转育成新不育系。Ｃ型不育系测交Ｆ２出现可育与不育的３∶１育性分离，回交一代出现１∶１的育性分离，表明恢复性受一对显性基因控制。
16 maize inbred lines with C type, Y type and Y Ⅱ type male sterile line measured cross, backcrossed to understand the relationship between male and female lines of CMS; F1 CMS sterile line measured cross in F1 Selfing, at the same time backcrossed with the C-type CMS. To analyze the restorative genetic behavior of C-type CMS lines. The results showed that five inbred lines (5003,330, 330,035-6 and 6-11) were C-CMS lines, three inbred lines (32-2, Zhen367 and i-1) Maintaining sterility of C-CMS lines; sterility of Y-CMS lines were maintained in 6 inbred lines such as TR3702, 77-1, 10-9, 5003, 449, 1 was the restorer line of YⅡ CMS line, and the sterility of YⅡ type CMS line was maintained in 5 inbred lines such as TR3702, Qing2,0,05-6,330 and 5003. 32-2 pairs of C type, bearing 10-9 pairs of Y type, 5003 pairs of Y type and Y Ⅱ type of backcrossed F1 all sterile, continuous backcross method can be used to transform into a new sterile line. C-type CMS line F2 showed fertile and sterile 3: fertility segregation, backcross generation appeared 1: 1 fertility separation, indicating that the recovery by a dominant gene control.
