Molecular ecological basis of high-yielding formation of rice and its application

Abstract

Abstract: 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.

Key words: Molecular cultivation science, Rice, Developmental genetics, Molecular ecology
