陇南市作为甘肃省玉米地方种质资源的重要分布区域，保存了具有独特遗传多样性的玉米地方品种，但近10 a已有部分品种发生遗传异化或丢失，当前玉米地方品种面临严重的保存危机。为保障甘肃省玉米产业的高质量发展乃至西北旱作农业可持续发展，势必开展陇南玉米地方品种种质资源保护的针对性研究。通过综述陇南玉米地方品种分布及特点、商业玉米品种推广种植布局演变情况、玉米地方品种种植现状以及陇南玉米地方品种种质资源保存利用情况等等，提出了构建多层级保种体系、区域适应性种质创新、陇南传统保种体系优化、种质资源共享创新等陇南玉米地方品种种质资源保存与利用的建议。

As a key distribution area of local maize germplasm resources in Gansu Province, Longnan has preserved local maize varieties with unique genetic diversity. However, over the past 10 years, some varieties have undergone genetic drift or have been lost, and local maize varieties are now facing a severe conservation crisis. To ensure the high-quality development of the maize industry in Gansu Province and the sustainable development of dryland agriculture in Northwest China, targeted research on the conservation of Longnan local maize germplasm resources is imperative. This paper reviews the distribution and characteristics of Longnan local maize varieties, the evolution of planting layout in commercial maize varieties, the current status of local variety cultivation, and the preservation and utilization of local maize germplasm in Longnan. Suggestions are proposed for establishing a multi-level conservation system, developing regionally adaptive germplasm, optimizing traditional preservation systems in Longnan, and innovating germplasm resource sharing mechanisms to promote the conservation and sustainable utilization of local maize germplasm resources in Longnan.
