品种真实性和纯度是保证良种遗传特性充分发挥的前提,是正确评定种子质量的重要指标。品种纯度的高低对于农业产品的质量和品质都有较大影响,近年来,农业部、省站、市站都高度重视对农作物品种纯度的抽查、检验。因为生产、经营假劣种子影响很大,不但会造成减产,同时也影响种子企业的声誉。因此品种真实性和品种纯度检验在种子生产、加工、贮藏及经营贸易中,具有重要意义和应用价值。电泳技术是测定品种纯度的一种快速检验方法。
The authenticity and purity of varieties are the preconditions for ensuring the genetic characteristics of elite seeds and an important indicator for correctly evaluating the quality of seeds. The purity of varieties has a great impact on the quality and quality of agricultural products. In recent years, the Ministry of Agriculture, provincial stations and municipal stations all attach great importance to the sampling and testing of the purity of agricultural varieties. Because of the great impact of producing and selling counterfeit seeds, it will not only result in the reduction of production, but also affect the reputation of seed enterprises. Therefore, the authenticity of varieties and varieties of purity test in the seed production, processing, storage and trade management, has important significance and application value. Electrophoresis is a rapid test to determine the purity of a variety.
