Abstract:

High-yield contests have been widely conducted globally, covering major food crops such as maize, wheat, soybeans, and rice. Successful experiences from international cases demonstrate that organizing yield contests may effectively promote the integration of superior seeds and agronomic practices, enhance crop breeding capabilities, and improve crop yields. Given the new challenges to food security in our country, it is necessary to explore how to draw on successful experiences of other nations to enhance our own potential for increasing crop production. The National Center of Technology Innovation for Maize adopts a high-yield technology dissemination chain centered around “quality seeds and good practice”, develops a biotechnological breeding innovation chain of high-yield genes and high-quality seeds varieties, and establishes a growth chain that spans from small-scale trials to large-scale applications. The goal is to establish a nationally replicable and scalable high-yield maize model, contributing to the vitalization and development of the seed industry.

Key words: high-yield contests, maize, yield increase, biotechnological breeding, seed industry vitalization.
