Progress and perspective of molecular design breeding

Abstract

Food is the most fundamental demand for human beings and the key factor that determines social development. In the future, world food security is still facing challenges. Molecular design breeding is an important approach to solving the problem of future food security. However, there are still many bottlenecks and problems in the theory, technology and standardization of molecular design breeding. To face the demand of future agriculture and food safety production, we summarized the food security problems that China and the world are facing, the development course of breeding technology and the achievements of molecular design breeding in China. We also pointed out the development trend of molecular design breeding in the future, and discussed the bottlenecks and countermeasures faced by molecular design breeding in China. In the end, focusing on the key questions in the scientific and technological innovation in future molecular design breeding, we laid out suggestions on the strategic planning of molecular design breeding towards 2035. The review provides important insights for future agricultural science and technology development.
