摘要: 玉米雄性不育化制种与常规玉米制种相比,具有免除人工去雄、降低生产成本、提高种子质量等优点,最大限度地发挥杂种优势。根据玉米雄性不育化制种特点,研究了恢复型玉米雄性不育杂交种ST501亲本的特征特性以及影响不育化制种质量及产量的各项因素,从亲本质量、花期调整、合理密植、科学施肥、病虫害防治、人工辅助授粉、适时收获等环节,提出了产量4500~5250公斤/公顷优质高产制种配套技术。

Abstract: Maize sterility seed production in maize with many excellences to common Seed production ,it con avoid emasculation by hand, reduce the seed production cost and improve seed quality ,it also can amplify heterosis mostly .Study the characteristics of the parents of heterosis restoring hybrids ST501 and the mainfactor that affects the yield and quality of seed production .Advance the selectivepreference cultivation combination for yields 4500kg to 5250kg per ha. From the preference cultivation combination for yields 4500kg to 5250kg per ha. From themain factor of the quality of the parents ,florescence regulation ,planting densities,prescribed fertilizer supplying, preventing diseases and insects ,artificial pollination ,timely gaining.
