品种纯度检验应包括两方面内容,即品种真实性和品种纯度。品种的真实性是指一批种子所属品种、种或属与文件描述(如标签、品种描述等)是否相符。品种纯度是指品种个体与个体之间在特征特性方面典型一致的程度,用本品种的种子数(或株、穗数)占供检验本作物种子数(株、穗数)的百分率表示。现结合工作实际,介绍幼苗鉴定和植株鉴定两种方法。 Variety purity testing should include two aspects, namely, the authenticity of species and species purity. The authenticity of a variety refers to the variety of seeds, species or genus and the description of the file (such as labels, description of varieties, etc.) is consistent. Variety purity refers to the degree of typical consistency between species and individuals in terms of their characteristic traits, expressed as a percentage of the number of seeds (or plants and spikes) of the cultivars used for testing the number of seeds of the crop (number of spikes per plant). Now combined with the actual work, introduced seedling identification and plant identification of two methods.
