摘　　要：介绍了 10多年来在水稻产量形成的发育遗传及其分子生态学基础的研究成果 ,分析了传统上应用比较生理学研究作物高产形成的优点与不足 ,强调应积极引进其它学科的研究内容及其方法 ,深化对作物栽培科学问题的认识 .提出了根据作物不同发育阶段的基因作用规律及其性质 ,研究制定相应措施 ,及时调控那些受显性遗传效应机制和加性效应基因与环境互作同向表达的性状是实现高产稳产的技术关键 ,认为这是作物遗传生态栽培学的主要特色与技术创新 .This paper introduced the developmental genetics and its molecular ecological basis of high yielding formation of rice in the past decade,and analyzed the advantage and the shortage of comparative physiological approach traditionally used in the research work on crop cultivation. It was emphasized to actively introduce the research contents and its methodology from relative disciplines to deeply understand the scientific issue,and suggested that the key to realize stable and high yielding of rice was to develop a rational cultivation system based on the properties of genetic effects on the traits in different developmental stages by controlling and regulating the traits governed by dominant effect genes and additive effect genes × environment in same direction,which was considered as the main characteristics and the technological innovation of modern crop genetic ecological cultivation science. Finally,the development trend of crop cultivation science shifting to molecular crop cultivation science was predicted and discussed.
