玉米杂交制种花期方案的研究

Study on Flowering Phase Adjusting Designs in Maize Crossing Breeding Seed Propagation

通过3年,时间对玉米杂交制种花期调节方案“母等父”与“父略早于母”进行了对比研究,结果表明,用“父略早于母”的花期调节方案比用传统的“母等父”产量有较大的提高。

Through five -year comparison of two flowering phase adjusting designs of＂the female parent waiting for the male panent＂ and＂ the male parent a little bit earlier than the female＂ in maize cross breeding seed propagation, the results showed that the latter design had relative higher yield than the formal one.
