关于玉米种子纯度鉴定方法分析

Analysis on the Method of Corn Seed Purity Identification

摘要: 玉米是禾本科玉蜀黍属植物，截止2020年，每年消耗一亿多吨用作粮食、饲料和工业原料，为了提高玉米的质量和产量、保护玉米品种权，种子管理者需要探索更加标准、有效的玉米种子纯度检验技术。本文通过比较分析种子形态鉴定法、幼苗形态鉴定法、小区种植鉴定法、生化鉴定法和分子标记检测技术这几类常用玉米种子纯度鉴定方法的优缺点及适用范围，为选择结果准确、简便易行、节约成本的方法提供理论依据，并对每种方法的优缺点进行评价，同时对未来种子纯度鉴定的发展趋势进行展望。

Abstract: Corn is a plant of the genus Poaceae. By 2020, it will consume more than 100 million tons per year as food, feed and industrial raw materials. In order to improve the quality and output of corn and protect the rights of corn varieties, seed managers need to explore more standard and effective Corn seed purity inspection technology. This paper analyzes the advantages and disadvantages of the commonly used corn seed purity identification methods, such as: seed morphological identification method, seedling morphological identification method, plot planting identification method, bi-ochemical identification method and molecular marker detection technology, and the scope of application. The cost-saving and cost-saving methods provide theoretical basis, and evaluate the advantages and disadvantages of each method, and at the same time forecast the future development trend of seed purity identification.
