About Seed Certification

Phases of Seed Certification

Certification shall be completed in six broad phases listed as under:

  1. Receipt and scrutiny of application
  2. Verification of seed source, class and other requirements of the seed used for raising the seed crop.
  3. Field inspections to verify conformity to the prescribed field standards.
  4. Supervision at post-harvest stages including processing and packing.
  5. Seed sampling and analysis, including genetic purity test and/or seed health test, if any, in order to verify conformity to the prescribed standards; and
  6. Grant of certificate and certification tags, tagging and sealing.
Field Area for Certification

There is no minimum or maximum limit for the area offered by a person for certification, provided the certified seed production meets all the prescribed requirements.

Unit of Certification

For the purpose of field inspection, the entire area planted under seed production by an individual shall constitute one unit provided:

  1. it is all under one variety;
  2. it does not exceed ten hectares;
  3. it is not divided into fields separated by more than fifty meters between them;
  4. it is planted with or is meant to produce seed belonging to the same class and stage in the generation chain;
  5. the crop over the entire area is more or less of the same stage of growth so that observations made are representative of the entire crop;
  6. the total area planted, by and large, corresponds to the quantity of seed reported to have been used; and the Certification Agency's permission had been obtained to sow a larger area by economizing on seed rate; if that the case;
  7. raised strictly as a single crop and never as mixed;
  8. not so heavily and uniformly lodged that more than one third of the plant population is trailing on the ground leaving no scope for it to stand up again thus making it impossible for the Certification Agency to inspect the seed crop at the appropriate growth stage in the prescribed manner;
  9. as far as possible, so maintained as to show adequate evidence of good crop husbandry thereby improving the reputation for certified seeds; and
  10. not grown as inter, companion or ratoon crop and inter cropping is applicable to on oilseeds and pulses crops only for production of certified seeds
Field Inspection
  1. The field inspection work which requires technically-trained personnel shall be performed by the persons who have been so authorized by the Certification Agency;
  2. Field inspection meant to verify those factors which can cause irreversible damage to the genetic purity or seed health shall be conducted without prior noticeto the seed producer;
  3. Soon after the completion of the field inspection, a copy of the report shall be handed over to the seed producer or his representative.

Harvesting, Threshing and Transportation
Seed crop meeting field standards for certification shall be harvested, threshed and transported to the seed processing plant in accordance with the guidelines issued by the Certification Agency. During these operations, seed producer will take all precautions to safeguard the seed from admixture and other causes of seed deterioration.

Seed Processing

Seed processing means cleaning, drying, treating, grading and other operations which will improve the quality of seeds. Seed from fields which conformed to the standards of certification at field stage shall, as soon as possible after the harvest will be brought at processing plant for processing. The screen aperture size specified shall be used for cleaning and grading of seeds so that typical contaminants such as weed seeds, small seeds, damaged seeds, broken and shriveled seeds, straw, chaff, leaves, twigs, stones, soil particles etc. are removed.

Seed Sampling

Soon after completion of the seed processing or after seed treatment as the case may be, the Certification Agency shall draw a representative composite sample as per procedure specified in Seed Testing Manual. The quantity of seed samples so drawn shall be sufficient to provide three samples of the size of submitted sample. The composite sample will be divided into three equal parts, and one shall be sent for analysis to a notified Seed Testing Laboratory, the second part to the seed producer and retain the third part as a guard sample.

Seed Testing

The Seed Testing Laboratory shall analysis the seed samples in accordance with the prescribed procedure and deliver the Seed Analysis Report to the Certification Agency as soon as may be, but not later than 30 days from the date of receipt of the samples unless the seed is subjected to such tests which require more than 30 days for completion of the test. The seed samples are analyzed for germination, physical purity, inert matter, moisture content and ODV test where ever necessary.

Seed Standards of Genetic Purity
  1. All the certified seed lots shall conform to the following Minimum standards for generic purity unless otherwise prescribed:
  2. Class Standards for Minimum Genetic Purity (%)
    Foundation 99.00
    (i) Varieties, composites, synthetics & multilines 98.00
    (ii) Hybrids 95.00
    (iii) Hybrids of cotton, TPS, muskmelon, brinjal &tomato 90.00
    (iv) Hybrid castor 85.00
  3. Grow-out Test

The Certification Agency shall conduct grow-out test to determine genetic purity of a seed lot whenever it is a pre-requisite for grant of the certificate and also on the seed lots where a doubt has arisen about the genetic purity. The grow-out test can be complemented by certain related laboratory tests. The Grow-Out-Test shall be conducted as per the procedure specified in IMSCS.

Recleaning, Resampling and Retesting

When a seed lot does not meet the prescribed seed standards, the Certification Agency on the request of seed producer may permit recleaning, resampling and retesting. The recleaning, resampling and retesting shall be permitted once. The seed lots recorded substandard in germination up to 25% less than the standard germination will be eligible for recleaning, resampling and retesting.

Packing, Tagging, Sealing and Issuance of the Certificate
  1. On receipt of Seed Analysis Report and the results of the grow-out test wherever prescribed, and if seed lot has met prescribed standards, the Certification Agency shall ensure packing, tagging and sealing and issuance of certificate expeditiously. An authorized official facsimile signature of the Certification Agency will be affixed on each certification tag indicating the official's name and designation and the container is sealed and then Certificate in Form no II is issued for the lot for marketing.
  2. Advance tagging may be permitted at the discretion of the Certification Agency with proper safeguards.
Refusal for Certification

The Certification Agency shall have the authority to refuse certification of any seed production field or any seed lot that does not conform to the Minimum Standards prescribed for that particular crop, either for field or for seed or for both. Such refusal will be subject to any appeal made to the Appellate Authority constituted, under Section 11(1) of the Seeds Act, 1966.


All Appeals against the decision of the Seed Certification Agency shall be made to the convener of the Appellate Authority, within 30 days of rejection. Every memorandum of appeal shall be in writing and shall be accompanied by

  1. A copy of the decision of the Certification Agency against which it has been preferred and shall set forth concisely and under distinct heads, the grounds of objection to such decision without any argument or narrative and
  2. A bank draft for Rs.100/-(Rupees One Hundred Only) in favour of "The Member - secretary, Telangana State Seed certification Agency" payable at Hyderabad towards fee to be credited to the Agency funds.
Validity Period of the Certificate

The validity period shall be nine months from the date of test at the time of initial certification. The validity period could be further extended for six months provided on retesting seed conforms to the prescribed standards in respect of physical purity, germination and insect damage for all seeds except vegetative propagating material for which lot shall be re-examined for seed standards specified for respective crop.


Validation is the process designed to verify the conformity of certified seed lots to the standards of Certification on expiry of the period up to which the initial certification or previous validation of the lot is valid up to .The validity period shall be nine months from the date of test at the time of initial Certification. The validity period could be further extended for 6 months provided on retesting seeds conforms to the prescribed standards in respect of physical purity, germination and insect damage. A seed lot will be eligible for extension of the validity period as long as it conforms to the prescribed standards.

The Seed producer who intends to get certified seed further validated shall approach concerned Senior Seed Certification Officer along with necessary details, documents and requisite fee before expiry of validity period.

Revocation of Certificate
If the Certification Agency is satisfied, either on reference made to it in this behalf or otherwise that
  1. The certificate granted by it under Section 9(3) of the Act has been obtained by misrepresentation as to an essential fact; or
  2. The holder of the certificate has, without reasonable cause, failed to comply with the conditions subject to which the certificate has been granted or has contravened any of the provisions of the Act or the Rules made there under, then, without prejudice to any other penalty to which the holder of the certificate may be liable under the Act, the Certification Agency may, after giving the holder of the certificate an opportunity of showing cause revoke the certificate, under the provisions of Section 10 of the Act.
Retention of Certification Records

The Certification Agency shall preserve in order all the documents including the guard samples pertaining to certification of each seed lot for one year from the date of grant/ extension of the certificate and two years in respect of rejected seed crops or lots from the date of communication of rejection unless and otherwise required for longer period.
