“1) “”Seed is of acceptable quality (seed health, physiological quality), and meets farmer needs (is adapted and aligned with farmer preferences).””

2) “”Based on the concepts of (1) genetic quality (including genetic purity, varieties, and biodiversity, e.g., local crop varieties); (2) health: pests and diseases are below specified threshold levels; (3) physiological quality: at the right physiological age—e.g., properly stored in the case of potato and yam or sourced from vigorous and healthy-looking crops for most other VPC (vegetatively propagated crop) seed; and (4) sound physical quality (size, shape and without mechanical damage). Quality is also shaped by acceptability of the seed to users (the users’ perception and intended use)”””
