把玉米自交系繁殖纳入回交群体模式，设计了玉米自交系选型留雄（确立轮回亲本群）保纯繁殖程序，在Ｍｏ１７保纯繁殖实践中应用收到良好效果，优越性突出。运用群体遗传学原理，通过回交群体遗传分析，揭示了群体基因与基因型及其频率等参数取决于基因型的基因对数与世代数，总趋势是随世代的推移，逐步回归最终同一于其轮回亲本群的规律，对玉米自交系选型留雄保纯繁殖程序予以有力的理论支持
The breeding of maize inbred lines into the backcross population model, designed maize inbred lines selected male (established reincarnated parent group) of pure breeding program, application in Mo17 purebred practice received good results, superiority prominent. Using population genetics, through backcross population genetic analysis revealed that the group of genes and genotypes and their frequency and other parameters depends on the genotypes of gene pairs and generations, the trend is with the passage of time, and gradually return to the same in the final The reincarnation of the parental group of the law of maize inbred lines selected male reproductive pure progeny to give a strong theoretical support
