玉米雄性不育化不育单交种利用方式的研究

Study on the Utilization Modes of Maize Male-sterile Single Hybrids

田间裂区试验结果表明,玉米雄性不育单交种与可育单交种按一定种子量比例(量比)掺和和以行数比例(行比)间种,均能显著提高玉米的产量。其中雄性不育单交种与可育单交种以量比3∶1的处理小区产量最高,其次是以行比4∶2的处理,但二者差异不显著,与其他处理相比差异显著。

Split plot experiment was designed to study the utilization modes of maize male-sterile single hybrids. The results showed that both mixing and interplanting the maize male-sterile single hybrids and fertile single hybrids according to certain quantity ratio and row ratio respectively could increase the yield of maize. The yield of the treatment planted according to 3 ： 1 quantity ratio was the highest and had no significant difference with the next one which planted according to 4 ： 2 row ratio. But there was significant difference between them and the others.
