Seed Generation Classes and Certification Standards
Under the Seeds Act, the national seed production chain maintains strict pedigree and quality standards across distinct generation classes.
Farmers should procure blue-tag certified seeds or white-tag foundation seeds to ensure varietal purity and high germination vigor.
- Breeder seed (Golden yellow tag): Primary seed produced under direct supervision of the originating agricultural breeder
- Foundation seed (White tag): Progeny of breeder seed multiplied by ICAR institutes and state agricultural universities
- Certified seed (Blue tag): Progeny of foundation seed certified by State Seed Certification Agencies for commercial distribution to farmers
- Truthful Label (TL green tag): Commercial seeds produced and labeled by private seed companies meeting minimum germination standards
Importance of Seed Replacement Rate (SRR)
Repeatedly sowing farm-saved seeds across multiple seasons leads to genetic deterioration, varietal contamination, and weed seed accumulation.
Increasing the Seed Replacement Rate by purchasing fresh certified seed every three seasons maintains hybrid vigor and yield potential.
- Hybrid seeds: Require 100 percent seed replacement every season because hybrid progeny segregates and loses vigor
- Self-pollinated crops: Wheat, paddy, and pulses benefit from replacing seed lots at least every three to four seasons
- Genetic vigor: Certified seeds ensure uniform flowering, synchronous maturity, and enhanced disease resistance
Seed Treatment Protocol and Government Subsidies
Before drilling, seeds should undergo sequential treatment combining chemical fungicides, insecticides, and biological inoculants (FIR concept).
Central schemes like the National Food Security Mission (NFSM) and state seed missions provide financial subsidies and free seed minikits of newly released varieties.
- FIR sequence: Treat with Fungicide first, Insecticide second, and Rhizobium/Azotobacter bio-inoculant third
- National Seeds Corporation (NSC): Procure certified seeds from authorized NSC outlets and state cooperative societies
- Seed minikits: Central schemes distribute free seed minikits of newly released high-yielding varieties through Krishi Vigyan Kendras

Common questions
What is the meaning of Seed Replacement Rate (SRR)?
SRR is the percentage of total cropped area sown with certified or quality seeds relative to traditional farm-saved seeds.
What does a blue certification tag on a seed bag indicate?
A blue tag certifies that the seeds meet official national certification standards for genetic purity, germination percentage, and physical cleanliness.
Why must hybrid seeds be replaced every single season?
Seeds harvested from hybrid crops segregate genetically in subsequent generations, causing loss of hybrid vigor and dramatic yield reductions.
