摘　　要：高产竞赛已经在国际上广泛开展,涵盖玉米、小麦、大豆、水稻等粮食作物,且国际上的成功经验表明,开展高产竞赛可以有效促进良种良法配套,增强品种培育能力,提升作物产量。在我国粮食安全面临新挑战的形势下,如何借鉴其他国家的成功经验以提升我国粮食增产潜力,需要进一步探索。国家玉米种业技术创新中心以“良种+良法”为核心的高产技术推广链,发展高产基因+高产品种的生物育种创新链,贯通小面积试验到大面积应用的增长链,实现全国范围内可复制、可推广的玉米高产模式,助力种业振兴发展。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.
