NABARD Seed Science Notes (ARD Syllabus): Seed Production, Seed Processing, Seed Village, Seed Certification and PYQs

These NABARD Grade A seed science notes, written for the NABARD 2026 and 2027 cycles, cover the syllabus line “Seed production, seed processing, seed village” from the agronomy block of the ARD syllabus, together with everything NABARD has asked around it: classes of seed and their tags, roguing, seed dormancy, Seed Replacement Rate, seed processing machines, germplasm conservation and seed laws. NABARD asked 10 seed-science questions from 2021 to 2025; each one is placed under its topic below, with the 2025-26 current affairs and 15 practice MCQs.

NABARD Grade A seed science syllabus for 2026 and 2027

In the official NABARD Grade A ARD syllabus, seed science sits inside the agronomy block, right after dryland agriculture: “Seed production, seed processing, seed village”. NABARD’s questions on it also reach into seed classes, certification, dormancy, seed replacement, germplasm conservation and seed laws, so these notes cover all of them.

Pattern: the seed chain (breeder → foundation) was asked in both 2023 and 2024. Seed production quality steps, processing machines and germplasm storage follow. Expect one to three seed questions per cycle. See also the earlier agronomy, meteorology and seed science PYQ analysis, or watch the NABARD ARD PYQ analysis video: Agronomy & Seed Science.

What is seed? Seed vs grain and the qualities of good seed

Botanically, a seed is a fertilised, mature ovule containing an embryo, stored food and a seed coat. In agriculture, seed is any plant part used for propagation: true seed, tubers (potato), setts (sugarcane), rhizomes (ginger) or cuttings. A grain is the same material grown for consumption.

BasisSeedGrain
PurposeSowing (propagation)Food, feed or industry
Genetic purityMust be true to varietyNot required
Viability and vigourEssentialNot required
ProductionUnder certification standards, with isolation and roguingNormal cultivation
TreatmentTreated with fungicides or bio-agentsNot treated

Characteristics of quality seed

  • Genetic purity: true to the variety, free of off-types.
  • Physical purity: free of inert matter, weed seeds and other crop seeds.
  • High germination and vigour: quick, uniform emergence in the field.
  • Optimum moisture: safe for storage (low moisture slows deterioration).
  • Seed health: free of seed-borne diseases and insects.
  • Uniform size and good test weight.

Good seed alone can raise yields by roughly 15–20%, which is why seed sits at the start of every productivity mission.

Seed production: classes of seed and the seed multiplication chain

India follows a three-generation system of seed multiplication: breeder → foundation → certified, starting from the breeder’s nucleus seed. Each class has a tag colour, and NABARD asked the chain in both 2023 and 2024.

Stage 0Nucleus seedSmall quantity of pure seed held by the original plant breederNo tag
Stage 1Breeder seedProduced under the breeder’s direct control (ICAR, SAUs)Golden yellow tag
Stage 2Foundation seedProgeny of breeder seed; produced by NSC, state seed corporations and seed farmsWhite tag
Stage 3Certified seedProgeny of foundation seed; produced by registered seed growers for farmersAzure blue tag

Truthfully labelled (TL) seed sits outside certification: the producer guarantees the label (germination, purity) without official certification. Its label is opal green. “Registered seed” belongs to the US four-class system, not India’s, and appears in NABARD only as a distractor.

NABARD Phase 1 ARD 2024

What is the progeny of breeder seed?

  1. Foundation seed
  2. Nucleus seed
  3. Certified seed
  4. Registered seed
  5. Truthfully labelled seed
Show answer
(a) Foundation seed. The same chain was asked in reverse in 2023 (“foundation seed is produced from: breeder seed”). “Registered seed” is the US class, and nucleus seed comes before breeder seed.
NABARD Phase 1 ARD 2023

Foundation seed is produced from:

  1. Nucleus seed
  2. Breeder seed
  3. Registered seed
  4. Certified seed
  5. Truthfully labelled seed
Show answer
(b) Breeder seed. Two cycles in a row tested the same link in the chain. Learn the chain both ways: parent and progeny.

Principles of seed production: genetic and agronomic

Genetic principles

  • Use the right seed source: each class must come from the class above it.
  • Isolation: keep a seed crop away from other varieties of the same crop by distance (isolation distance) or time (different flowering dates). Cross-pollinated crops such as maize need far greater isolation than self-pollinated crops such as wheat or rice.
  • Roguing: removing off-type plants, diseased plants and plants of other varieties before they shed pollen.
  • Avoid volunteer plants: choose a field not sown with the same crop in the previous season.
NABARD Phase 1 ARD 2023

Roguing means:

  1. Improving soil fertility
  2. Treating plants with biofertilisers
  3. Removing off-type plants
  4. Introducing new varieties
  5. All of the above
Show answer
(c) Removing off-type plants. Roguing protects genetic purity, which is why it is a field-inspection item in seed certification.

Agronomic principles

  • Region and season: grow seed where the crop flowers and matures well with dry weather at harvest.
  • Field selection: fertile, well-drained, free of soil-borne diseases and volunteer plants.
  • Sowing and seed rate: lower seed rates and wider spacing than grain crops make roguing easier.
  • Nutrition, irrigation and plant protection as for a healthy crop.
  • Harvest at physiological maturity, then dry, thresh and process carefully to avoid mechanical damage.

Hybrid seed production

Hybrid seed is the first-generation (F1) progeny of two genetically different parents, and must be bought fresh every season. Pollination is controlled by detasselling (maize), hand emasculation (cotton, vegetables) or cytoplasmic male sterility (CMS) using A, B and R lines (rice, pearl millet, sunflower). Read more in C4S notes on hybrid seeds.

Seed Replacement Rate (SRR) and Varietal Replacement Rate

Seed Replacement Rate (SRR) is the percentage of a crop’s area sown with certified or quality seed rather than farm-saved seed. It is the most important indicator of seed-sector performance, and NABARD asked it directly in 2025.

  • Recommended SRR norms: about 25–33% for self-pollinated crops (wheat, rice, pulses), 35–50% for cross-pollinated crops and 100% for hybrids.
  • Varietal Replacement Rate (VRR) measures how quickly old varieties are replaced by newly released ones.
  • A higher SRR is linked to higher productivity, which is why seed village and seed hub programmes target it.
NABARD Phase 1 ARD 2025

Which term measures the cultivated area sown with certified (quality) seed compared with the area sown with farm-saved seed?

Show answer
Seed Replacement Rate (SRR). Revise alongside seed multiplication ratio and VRR. Read the C4S note on SRR.

Seed certification and seed testing

Seed certification

Seed certification is a legally sanctioned system of quality control during seed multiplication. Under the Seeds Act, 1966, certification is voluntary, while labelling of notified kinds and varieties is compulsory. It is carried out by State Seed Certification Agencies, with the Central Seed Certification Board advising the government.

  1. Verify seed source
  2. Field inspection
  3. Sampling
  4. Seed testing
  5. Tagging and sealing

Field inspections check isolation, off-types, roguing and diseases. The certificate is generally valid for nine months from the date of testing, and can be revalidated for six months after retesting.

Seed testing

TestWhat it measures
Physical purityPure seed, inert matter, weed and other crop seeds
GerminationPercentage of seeds producing normal seedlings
MoistureSafe moisture for storage
Other distinguishable varieties (ODV)Genetic purity in the seed lot
Viability: tetrazolium (TZ) testQuick check of live embryos using 2,3,5-triphenyl tetrazolium chloride
Seed healthSeed-borne pathogens and insects

Seed testing follows ISTA (International Seed Testing Association) rules; India’s Central Seed Testing Laboratory functions at the National Seed Research and Training Centre, Varanasi.

Seed dormancy: causes and methods of breaking it

Seed dormancy is the state in which a viable seed does not germinate even under favourable conditions. It prevents pre-harvest sprouting but delays sowing.

CauseMethod to break it
Hard, impermeable seed coatScarification (mechanical or acid), impaction, hot water
Chemical inhibitors in seedLeaching (soaking in running water)
Immature embryo or cold requirementStratification (moist chilling)
Hormonal (high abscisic acid)Gibberellic acid (GA₃), potassium nitrate, thiourea
NABARD Phase 1 ARD 2023

Which method is NOT used to break seed dormancy?

  1. Leaching inhibitors
  2. Scarification
  3. Auxin and abscisic acid
  4. Stratification
  5. Impaction
Show answer
(c) Auxin and abscisic acid. ABA induces dormancy; gibberellins break it. Every other option is a genuine method.

Seed processing: steps, machines and seed treatment

Seed processing converts harvested seed into a clean, uniform, treated and packed product ready for sale and sowing. It removes inert matter, weed seeds, other crop seeds and damaged seed, and upgrades the lot.

  1. Receiving
  2. Drying
  3. Pre-cleaning
  4. Cleaning
  5. Grading
  6. Upgrading
  7. Treating
  8. Bagging and labelling
  9. Storage
Seed processing machines and what they separate
MachineSeparates byUse
Scalper / pre-cleanerSize (coarse)Removes stalks, stones, large trash
Air-screen cleaner PYQ 2022Size, shape and weight (screens + air)Basic cleaner: removes inert matter, chaff, light seeds
Indent cylinderLengthSeparates long and short seeds
Specific gravity separatorDensity (weight)Removes light, immature, insect-damaged seed
Spiral separatorShape (roundness)Separates round seeds (mustard) from flat ones
Velvet roll / magnetic separatorSurface textureRemoves rough-coated weed seeds (dodder)
Seed treaterNot a separatorCoats seed with fungicide, insecticide or bio-agents
NABARD Phase 2 ARD 2022

Which machine removes inert matter and adulterants from seed?

Show answer
Air-screen cleaner. Learn each machine by the property it separates on: size, length, density, shape or surface.

Seed treatment

Seed treatment protects seed and seedlings from seed-borne and soil-borne pests and diseases: fungicides (thiram, captan, carbendazim), insecticides, and bio-agents such as Trichoderma and Pseudomonas fluorescens (NABARD 2024 asked that disease-suppressing microbes are “antagonists”). Rhizobium and PSB inoculation is a biofertiliser treatment for pulses.

Seed storage and germplasm conservation

Seed life in storage depends mainly on moisture and temperature: each fall in seed moisture and storage temperature lengthens storage life.

  • Orthodox seeds (most cereals, pulses, oilseeds) can be dried to low moisture and stored cold for long periods.
  • Recalcitrant seeds (coconut, mango, jackfruit, cocoa, rubber) die if dried, so they cannot be stored conventionally.
  • Cryopreservation stores germplasm, embryos or pollen in liquid nitrogen at about −196°C PYQ 2024.
  • National Gene Bank at ICAR-NBPGR, New Delhi; the National Seed Vault at Chang La, Ladakh (about 17,300 ft), set up by DRDO and ICAR-NBPGR, uses natural cold PYQ 2025.
NABARD Phase 2 ARD 2025

Where is India’s National Seed Vault?

  1. Chang La Pass, Ladakh
  2. Sriganganagar, Rajasthan
  3. Kapurthala, Punjab
  4. Rohtak, Haryana
  5. Shikohabad, Uttar Pradesh
Show answer
(a) Chang La, Ladakh. Natural cold storage there preserves germplasm. NABARD 2024 also asked that seeds are cryopreserved in liquid nitrogen.

Seed village: concept, Seed Village Programme and benefits

A seed village is a village where a trained group of farmers produces quality seed of selected crops and varieties to meet its own needs and those of nearby villages, at the right time and an affordable price. It is a named NABARD syllabus keyword because it is the cheapest way to raise the Seed Replacement Rate in places formal seed supply does not reach.

How the seed village concept works

  1. Select village and farmers
  2. Supply foundation or certified seed
  3. Train in seed production
  4. Grow under supervision
  5. Process, store and share or sell

Seed Village Programme (Beej Gram Yojana)

The Seed Village Programme is a component of the Sub-Mission on Seed and Planting Material (SMSP), now under the National Food Security and Nutrition Mission. Its aim is to upgrade the quality of farm-saved seed.

ComponentAssistance
Distribution of foundation/certified seed50% of seed cost for cereals; 60% for pulses, oilseeds, fodder and green manure crops, for one acre per farmer
Farmers’ training₹15,000 per group of 50–150 farmers on seed production and post-harvest seed technology
Funding pattern60:40 Centre–state (90:10 for north-eastern and Himalayan states)

Benefits of seed villages

  • Timely, local supply of quality seed at lower cost.
  • Higher SRR and productivity; faster spread of new varieties.
  • Extra income for seed-grower farmers; scope for FPOs and seed cooperatives.
  • Seed self-sufficiency and resilience after floods or droughts.

The cooperative route was strengthened by Bharatiya Beej Sahakari Samiti Ltd (BBSSL), the national multi-state seed cooperative approved in January 2023, which NABARD asked about in the 2024 ESI paper. For pulses, ICAR seed hubs play a similar role.

Seed science current affairs for NABARD Grade A 2026

Draft Seeds Bill, 2025

The Ministry of Agriculture released the Draft Seeds Bill, 2025 on 12–13 November 2025 for public comment, to replace the Seeds Act, 1966 and the Seeds (Control) Order, 1983. Key proposals:

  • Mandatory registration of seed varieties after Value for Cultivation and Use (VCU) testing; varieties notified under the 1966 Act are deemed registered.
  • Registration of dealers, distributors, producers, processors and nurseries; QR-coded traceability.
  • Graded penalties: trivial, minor and major offences; major offences (spurious or unregistered seed) up to ₹30 lakh fine and three years’ imprisonment.
  • Farmers may continue to save, exchange and sell farm-saved seed, except branded seed.

Status check: earlier Seeds Bills (2004 and 2019) never became law. The government said in January 2026 that it would take the new law to Parliament; confirm whether it has been introduced or passed before your exam. Read the background in Government plans amendments to the Seed Act.

National Mission on High Yielding Seeds

Announced in the Union Budget 2025-26 (1 February 2025), with ₹100 crore for 2025-26. Its three aims: strengthen the research ecosystem; develop and propagate high-yielding, pest-resistant and climate-resilient seeds; and make more than 100 seed varieties released since July 2024 commercially available. The same Budget announced a second gene bank with 10 lakh germplasm lines.

Other seed developments

  • 109 high-yielding, climate-resilient and biofortified varieties of 61 crops were released by the Prime Minister on 11 August 2024.
  • SATHI portal (Seed Traceability, Authentication and Holistic Inventory), launched in April 2023, tracks seed through the supply chain to curb spurious seed.
  • Plans for modern seed breeding facilities: see India to set up 5 modern seed breeding facilities.

How to prepare seed science for NABARD Grade A 2026 and 2027

  1. Learn the seed chain with tag colours, parent and progeny, both ways.
  2. Learn production quality steps: isolation, roguing, certification stages, seed tests.
  3. Learn processing machines by the property each separates on.
  4. Learn seed village as concept + programme + assistance + benefits; it suits a Phase 2 descriptive question.
  5. Add current affairs: Seeds Bill 2025, NMHYS, gene bank, SATHI, BBSSL.
  6. Solve all 10 PYQs and the 15 MCQs above, then revise the facts table.
Common traps: “registered seed” as an option (US class, not Indian); ABA vs GA₃ in dormancy; certification voluntary vs labelling compulsory; orthodox vs recalcitrant seed; and the year-to-year status of the Seeds Bill.

NABARD seed science: frequently asked questions

What is the seed science syllabus for NABARD Grade A?

The NABARD ARD syllabus lists “seed production, seed processing, seed village” in its agronomy block. NABARD’s questions also cover classes of seed and tags, roguing, seed certification and testing, dormancy, Seed Replacement Rate, germplasm storage and seed laws.

Is seed science important for NABARD Grade A 2026?

Yes. NABARD asked 10 seed science questions from 2021 to 2025, including two or three in each recent cycle, and the breeder-to-foundation seed chain came in both 2023 and 2024. For NABARD 2026, add the current affairs too: the Draft Seeds Bill 2025, the National Mission on High Yielding Seeds and the second gene bank.

How many seed science questions come in NABARD Grade A?

NABARD asked 10 seed science questions from 2021 to 2025, usually one to three per cycle, mostly in Phase 1 ARD. The breeder-to-foundation seed chain was asked in both 2023 and 2024.

What are the classes of seed in India?

Nucleus seed, breeder seed (golden yellow tag), foundation seed (white tag) and certified seed (azure blue tag). Truthfully labelled seed carries an opal green label and is not officially certified.

What is a seed village?

A village where a trained group of farmers produces quality seed of selected crops for its own needs and nearby villages.
