Release of Variety in India

The release of a variety is the official approval process through which a newly developed crop variety is evaluated and recommended for cultivation in India. It ensures that only high-yielding, stable, disease-resistant, and quality varieties reach farmers.

Objectives of Variety Release

• Increase crop productivity.
• Identify superior varieties.
• Ensure disease and pest resistance.
• Improve quality and adaptability.
• Maintain genetic purity.
• Support certified seed production.

Need for Variety Release

A scientific release system ensures that only well-tested and superior varieties are cultivated. It protects farmers from poor-quality seeds and improves agricultural productivity.

Organizations Involved

• ICAR – Coordinates agricultural research and variety evaluation.
• AICRP – Conducts multi-location testing of new varieties.
• State Agricultural Universities (SAUs) – Develop and evaluate crop varieties.
• Central Agricultural Universities (CAUs) – Conduct regional crop improvement research.
• Indian Institute of Seed Science (IISS) – Research on seed quality and technology.
• Central Seed Committee (CSC) – Advises the Government on release and notification.
• Central Sub-Committee – Examines and recommends varieties for central release.
• State Variety Release Committee (SVRC) – Releases varieties for individual states.
• Department of Agriculture & Farmers Welfare – Issues official notification.
• PPV&FRA – Registers varieties and conducts DUS testing.
• National & State Seed Corporations – Produce and distribute quality seed.

Methods of Variety Development

• Mass Selection
• Pure Line Selection
• Pedigree Method
• Bulk Method
• Backcross Breeding
• Mutation Breeding
• Hybrid Breeding
• Marker-Assisted Selection (MAS)
• Genome Editing (CRISPR)

Requirements for Variety Release

• High yield
• Stable performance
• Disease and insect resistance
• Abiotic stress tolerance
• Good quality traits
• Distinctness, Uniformity and Stability (DUS)

Stages of Variety Testing

1. Station Trial
2. Initial Evaluation Trial (IET)
3. Advanced Varietal Trial-I (AVT-I)
4. Advanced Varietal Trial-II (AVT-II)
5. Adaptive Research Trial
6. Front Line Demonstration (FLD)

Proposal for Release

The breeder submits complete information including pedigree, breeding method, yield performance, disease resistance, quality traits, DUS data, and seed availability for evaluation.

Variety Release Process

Parent Selection → Hybridization/Selection → Station Trial → IET → AVT-I → AVT-II → Disease & Quality Evaluation → Release Proposal → Committee Approval → Government Notification → Breeder Seed → Foundation Seed → Certified Seed → Distribution to Farmers

Types of Release

• Central Release: Recommended for cultivation in more than one state.
• State Release: Recommended for cultivation within a specific state.

Variety Notification

After approval, the Government of India officially notifies the variety under the Seeds Act, allowing certified seed production and commercial cultivation.

Seed Production Chain

Nucleus Seed → Breeder Seed → Foundation Seed → Certified Seed → Farmers

Importance of Variety Release

• Improves agricultural productivity.
• Ensures quality seed availability.
• Promotes disease and stress-resistant varieties.
• Maintains varietal purity.
• Supports food and nutritional security.

Conclusion

The variety release system in India is a systematic process that ensures only scientifically tested, high-performing, and genetically stable crop varieties are released for cultivation. It plays a vital role in sustainable agriculture and national food security.
