玉米种质资源是保障玉米产业高质量发展的战略性资源，是玉米科技原始创新和新品种选育的物质基础。玉米种质资源研究对推动玉米种业创新和玉米产业可持续发展具有十分重要的价值和意义。黑龙江地处中国最北部，独特的高纬度、高寒气候和地理条件孕育了丰富的寒带早熟玉米种质资源。本文对黑龙江省在玉米种质资源收集、保存、评价、基因挖掘及创新利用等方面的研究进展进行系统阐述，对黑龙江省玉米种质资源研究存在的问题和未来的发展方向进行探讨和展望，为黑龙江玉米种质资源的有效利用和产业发展提供参考。

Maize germplasm resources serve as strategic resources to ensure the high-quality development of the maize industry, and provide the material foundation for the original innovation and variety breeding of maize. Research on maize germplasm resources is of great value and significance in promoting innovation in the maize seed industry and sustainable development of the maize industry. Heilongjiang Province lies in the northernmost part of China, unique high latitude, cold climate, and geographical conditions have bred rich germplasm resources of early maturing maize in the cold zone. This article systematically analyzed and evaluated the research progress in the collection, preservation, evaluation, gene discovery, innovative utilization of maize germplasm resources in Heilongjiang Province. And the existing problems and future development directions of maize germplasm resources research in Heilongjiang Province were discussed and forecasted, aiming to provide a reference for the effective utilization and industrial development of maize germplasm resources in Heilongjiang Province.
