Detailed procedures for variety development through AICRP, multilocation testing (IVT/AVT 3-year trials), workshop identification, variety release process via CVRC (All India) and SVRC (state-specific), notification by Government of India, NSC/APSSDC/APSSCA functions, and committee composition for variety releasing decisions.
Covers seed production importance, historical development (Swedish seed association 1886, AOSCA 1969), India’s seed production evolution, NSC/SSC/SSCA establishment, Seed Act 1966 provisions, statuary bodies (Central Seeds Committee, Central Seed Certification Board, CSTL, SSTL), seed law enforcement, inspector powers, and offenses/penalties.
