    摘要:

    试验以不育农大108×高油5580、不育农大108×高油6528、不育农大108×高油4515、不育潞玉13×高油5580、不育潞玉13×高油6528、不育潞玉13×高油4515为材料对普通玉米高油化三利用技术进行研究。不育普通玉米和高油授粉者种植行比为3∶1和3∶3。试验得到以下结果:6个组合杂交当代子粒油分含量增加明显,说明利用普通玉米高油化模式可改进普通玉米品质;以不育农大108普通玉米为母本有一组合产量增加幅度较大,但油分增加幅度不大,说明组合选择较合理,但种植行比还有一定的空间;以不育潞玉13为母本的组合产量和油分均增加,说明不育潞玉13可作为当地高油玉米三利用技术的主推品种。

    Abstract:

    TEU(three effects utilization) model is an important measure to produce high oil grain with normal corn hybrid by oil xenia effect.To study its effects in maize production,4 pairs of CMS normal hybrids and high oil pollinator,namely Cms-ND108×HO5580(1),Cms-ND108×HO6528(2),Cms-ND108×HO4515(3),Cms-Luyu13×HO5580(4),Cms-Luyu13×HO6528(5) and Cms-Luyu13×HO4515(6) were used with large plot in the experiment.The row ratio of CMS normal hybrids and pollinator was 3∶1 and 3∶3.The results showed that oil content of seed of 6 combinations was significantly increased.This indicated that quality of common maize grain could be improved by growing it with high oil cultural pattern.The yield of a combination with Cms-ND108 as mother was greatly increased but oil content was slightly increased,which indicated that the combination was proper but row ratio should be changed.The yield and oil content of combinations with Cms-Luyu13 as mother was both increased.This indicated that Cms-Luyu13 should be widespread in local TEU model of high oil corn.
