Introduction Seed as the foundation of agriculture: Determines crop productivity and food security. Need for improved varieties to combat climate change, pests, and diseases. Variety release & notification: Formal process to ensure only scientifically evaluated varieties reach farmers. Objective: Understand legal, scientific, and procedural aspects in India.
Definition of Variety A variety is a plant grouping within a species with distinct and stable characteristics. Defined under Seeds Act, 1966 and PPV&FR Act, 2001. May be conventional, hybrid, or genetically modified.
Objectives of Variety Release Introduce high-yielding, resilient cultivars. Encourage genetic diversity in cropping systems. Validate adaptability to different agro-climatic zones. Enhance farmer income and food security. Enable systematic seed production and certification.
Types of Varieties Research varieties: Developed by ICAR, SAUs, or private firms. Hybrids: Crosses that offer heterosis (hybrid vigor). Farmers’ varieties: Indigenous and traditionally selected. GM varieties: Contain transgenic traits (e.g., Bt cotton). Public vs private: Based on origin of breeding institution.
Institutions Involved ICAR: Coordinates breeding via AICRPs. CVRC: Approves varieties of national significance. SVRC: Approves state-specific varieties. DAC&FW: Issues notifications. PPV&FR Authority: Registers varieties and ensures breeders’ rights.
Variety Release: Overview Breeding: Identification through scientific crossing and selection. Evaluation: Multi-location and multi-year trials. Proposal Submission: By sponsoring institutions. Committee Review: CVRC/SVRC evaluate and approve. Release Announcement: For cultivation recommendation.
Stages of Testing Initial Evaluation Trial (IET): Preliminary performance data. Advanced Varietal Trials (AVT I & II): Conducted for at least two years. Agronomic Trials: Determine optimal sowing date, spacing, nutrient dose. Biotic & Abiotic Stress Screening: Resistance to stress factors.
Multi-location Trials Conducted under AICRP across agro-climatic zones. Ensure wide adaptability and performance stability. Trials include standard checks for comparison. Data analyzed by crop experts.
Criteria for Release Yield: 10–15% improvement over best check. Quality traits: Grain quality, oil content, etc. Stress resistance: Biotic and abiotic. Stability & Adaptability across years and regions. End-use suitability like milling, cooking, etc.
Proposal Submission Submitted by breeder or institute to CVRC/SVRC. Includes performance data from IET/AVT. DUS test reports and agronomic trial results. Photographs, breeding history, and pedigree.
Central vs. State Release CVRC: For varieties suitable in >1 agro-climatic zone or >2 states. SVRC: For state-specific varieties. Difference lies in scope, not in procedure.
Variety Notification Provides legal status to the variety under Section 5 of Seeds Act. Mandatory for seed certification and marketing. Published in the Official Gazette of India.
Steps for Notification Proposal to Seed Division, DAC&FW. Reviewed by Central Sub-Committee on Crop Standards. Notification issued via e-Gazette. Added to official Seed Variety List.
Difference: Release vs Notification Release: Recommendation for cultivation (by CVRC/SVRC). Notification: Legal approval for seed sale (by DAC&FW). Notification mandatory for seed certification.
Role of DUS Testing Required under PPV&FR Act, 2001. Ensures Distinctiveness, Uniformity, and Stability. Conducted by DUS Testing Centers.
Farmer's Varieties Recognized under PPV&FR Act. Registered based on novelty or traditional use. Can be released and notified if performance is proven.
Challenges in Current System Long duration for multi-year testing. Limited infrastructure and bureaucratic delays. Underutilization of farmer's knowledge.
Recent Developments SeedNet portal and online Gazette notifications. Biofortified and climate-resilient varieties. Involvement of private sector in trials.
Future Directions Digital DUS testing and AI integration. Genomics-assisted breeding. Greater farmer participation and PPP models.
Conclusion Ensures quality, productivity, and safety in agriculture. System involves scientific rigor and legal oversight. Future: Speed, inclusion, and innovation.
