摘要 建国50 年来,山东玉米科技工作者在遗传育种、栽培理论与技术、病虫防治等方面进行了大量研究并取得显著成就。在省级以上学术刊物发表论文500 多篇,出版书籍23 部。1978~1998 年取得省部级以上科技成果奖96 项。选育优良自交系20 多个,育成杂交种100 多个。科技进步推动了生产发展。1949 ~1999 年,山东玉米播种面积扩大1 .93 倍,单产提高5 .23 倍,总产增加17 .3 倍。21 世纪初,山东玉米遗传育种研究将围绕提高单产和改善品质两个主要目标开展工作。产量指标为900 ~1000kg/666 .7m2 ,并培育各种增值玉米。各种现代高新技术将被广泛应用于育种过程。生产技术水平也会有较大提高,全省玉米平均产量将达到500kg/666 .7m2 以上。本文围绕上述目标。 Since the founding of our People's Republic,maize science and technology workers of Shandong Province have made numerous studies in many fields such as inheritance and breeding,theories and techniques of cultivating,prevention and cure of plant diseases and insect pests and so on.Prominent achievements have been acquired.These could be reflected by 96 awards of science and technology from 1978 to 1998,more than 20 selected inbred lines and over 100 bred hybrids.From 1949 to 1999,planting area of maize in Shandong Province has been expanded by 19.3 times,unit yield increased by 5.23 times,and total yield increased by 17.3 times.At the beginning of 21st century,increasing yield per unit area and improving quality are the central targets for studies on maize inheritance and breeding of Shandong Province.Hybrids that have potential yield 900~1000kg/666.7m 2 and value enhanced corn varieties for special purpose will be cultivated.Modernized hi-technology will be applied in breeding and maize productive technology level will be rose greatly.In future ,maize average yield will reach more than 500kg/666.7m 2.According to these targets,emphasized tasks of science and technology research of maize in Shandong Province are put forward in this paper.
