Trueness to variety; the presence of inert matter, seed of other crops, or weed seed; germination percentage; vigor; appearance; and freedom from disease are important aspects of seed quality. means seed lots that have met the minimum standards and hence are of high cultivar purity, high genetic and physical purity, are free from noxious weeds, seed borne diseases and pests and have germination capacity; means seed lots that have met the minimum standards and hence are of high cultivar purity, high genetic and physical purity, are free from noxious weeds, seed borne diseases and pests and have germination capacity; Centre for Development of Advanced Computing, Hyderabad. Eg. Seed quality is a relative term and means the degree of excellence when compared to an acceptable standard.

Ministry of Electronics and Information Technology (MeitY). Seed quality depends upon the physical conditions that the mother plant is exposed to during growth stages, as well as harvesting, processing, storage and planting. Define seed quality.

The figure (below) shows the flow of seed from the plant breeder to the farm and the characteristics of good seed. Seed is a basic input in agriculture. Quality Seed Quality seed is defined as varietally pure with a high germination percentage, free from disease and disease organisms, and with a proper moisture content and weight.
