品种纯度鉴定包含两方面内容:其一是品种的真实性,即所检品种是否名实相符,是否符合该品种的特征特性;其二是品种的群体内个体之间特征特性是否一致。符合本品种特征特性,基本一致的个体占供检本作物样品总数的百分率,即为本品种纯度。玉米品种纯度鉴定方法依据其所用方法性质的不同,可分为形态鉴定法和电泳鉴定法。 1 形态鉴定法有差异,才能鉴别。在鉴定品种时,必须千方百计找出种子、幼苗、植株形态特征特性的差异。据其差异,
Purity identification of cultivars includes two aspects: one is the authenticity of the cultivars, that is, whether the tested cultivars match the characteristics of the cultivars; whether the characteristics of the cultivars conform to the characteristics of the cultivars. In line with the characteristics of this species characteristics, basically the same as a percentage of the total number of samples for the seized crop, the purity of the species. Purity identification of maize varieties based on the nature of the method used can be divided into morphological identification and electrophoresis. A morphological identification of differences in order to identify. In the identification of varieties, we must make every attempt to find out the seed, seedling, plant morphological characteristics of the differences. According to their differences,
