Abstract: In order to provide a reference basis for the creation of strong advantage combinations and the study of high-yielding cultivation technology of hybrid wheat, the author summarizes the biological rules, which include yield components and contributions to grain yield, heterosis of photosynthetic performance and matter production, population structure, source-sink relationships, root development and so on, in the process of yield formation of hybrid wheat. The author puts forward the main strategies to further exploit the heterosis of wheat, including the excavation of potential of grain number per spike and 1000-grain weight, increase in sink-source ratio, improvement of sink-source ratio, application of precision cultivation and so on. It is hoped to provide guidance for accelerating the application of hybrid wheat.
