摘　　要：对不育系繁殖的几个重要措施不同父母本行比、母本密度、株高差和喷施赤霉素等综合因素初步研究表明,在父母本行比为2∶2～2∶6时,行比越大,产量越高。当母本密度为11×104株/667 m2时,繁殖产量最高,抽穗50%时喷施2g/667 m2的赤霉素,对繁殖产量和母本异交结实都起一定的作用。In this paper main study was conducted on some important measures of sterile lines roproduction（different row ratio between maternal and father plants, female parent density, different parents height and spraying GA and so on）. The results showed that when the row ratio is from 2：2 to 2：6, the larger the row ratio is, the higher yield becomes. The maximum reproduction yield can be gained when the female parent dentist is 11 × 10^4/667 m^2. Spraying 2 g/667 m^2 GA in 50% spikes presenting period is good to reproduction yield and the female outcross seed set.
