主要农作物产量性状的遗传网络解析学术交流及战略调研

The major research project of "Dissection of Genetic Networks Controlling Yield Traits in Major Crops" aims at the major demand of food security and the frontier fields of life science. In integration phase, the project focuses on the network analysis of specific common traits for main crop, the genetic mechanism of yield and quality in rice, construct genetic network of key traits for maize yield and quality, genetic network analysis of yield and quality traits in wheat, molecular design breeding of main crops. The genetic regulatory network of crop architecture development and grain formation of maize, rice and wheat is analyzed and clarified. The interaction regulation rules between major genes and genes affecting for yield and quality traits are analyzed and clarified, which provides theoretical basis for high-yield and high-quality molecular design breeding. For the nuclear problems of the project, we held academic exchanges and seminars, summarized the research progress, compiled the final evaluation summary report, research results report and strategic research report of the project. Expand the impact of the project in the field of academia, and enhance the initial innovation of genetic breeding in major crops.
