· Essential in maintaining crop uniformity and performance
❌ (a) Absence of inert matter: This relates to physical purity, not genetic purity.
❌ (b) Absence of weed seed: Also a component of physical purity, important but unrelated to genetic identity.
❌ (d) Absence of defective seeds: Defective or shriveled seeds are counted in seed viability tests, not genetic purity.
