种子质量是指种子这种特殊商品所要满足人们使用种子所要求的特征特性
的总和。种子质量包括两个方面，一是种子的品种属性，二是种子的播种品质。
品种属性指品种纯度、丰产性，抗逆性、早熟性、产品的优质性及良好的加工工
艺品质等。播种品质是指种子的充实饱满度、净度、发芽率、水分、活力及健康
度等。高质量的种子应当兼有优良的品种属性和良好的播种品质，缺一不可。
评价种子质量有多个指标，其中尤以品种纯度最为重要，品种纯度指品种在
特征特性方面典型一致的程度，用本品种的种子数占供检本作物样品种子数的百
分率表示。在检测品种纯度之前首先要查明所检品种的真实性。种子的真实性是
指供检品种与文件记录 ( 如标签等 )是否相符。此外评价种子质量的指标还有
种子净度、水分、发芽率、健康度等。
种子质量标准对种子的要求并不包括种子质量的全部内容，在我国只是种子
的纯度、净度、水分、发芽率四项指标。因此符合种子质量标准的种子（即合格
种子）并不证明种子没有质量问题。特别是一些很重要的品种属性如丰产性、适
应性、抗逆性及健康状况等没有在种子质量标准中体现。 质量指标是指生产商
必须承诺的质量指标，按品种纯度、净度、发芽率、水分指标标注。国家或地方
种子质量有标准的，生产商承诺的指标不能够低于规定的标准。
