Registrable Plant Varieties and Exclusions from Protection

Updated 11 October 2026 · Fact-checked

A new plant variety is registrable under the PPVFR Act, 2001 if it is novel, distinct, uniform and stable (section 15) and has an acceptable denomination. Section 29 bars registration on grounds such as public order or harmful technology, and section 13 requires registered varieties to be entered in the National Register of Plant Varieties.

Understand Registrable Varieties and Exclusions from Protection

The PPVFR Act, 2001 protects plant varieties through breeders' rights. A variety is a plant grouping (not a micro-organism) within a single botanical taxon of the lowest known rank. It is defined by the expression of characteristics from a given genotype, can be distinguished from other groupings by at least one characteristic, and stays unchanged after propagation. The definition also includes propagating material, extant, transgenic, farmers' and essentially derived varieties.

Not every variety gets protection. Section 15(1) says a new variety is registered if it meets four tests: novelty, distinctiveness, uniformity and stability. Students call these NDUS, and the last three together are often called the DUS test. Each test has a statutory meaning in section 15(3).

Novelty is about commercial sale. At the filing date, the propagating or harvested material must not have been sold or disposed of, by or with the consent of the breeder, for exploitation: in India earlier than one year before filing; outside India earlier than six years for trees or vines, and four years for other plants. Trials without sale do not affect novelty. Common knowledge gained in some other way also does not defeat novelty.

Distinctness means clearly distinguishable by at least one essential characteristic from any other variety that is common knowledge in any country at the filing date. Uniformity means sufficiently uniform in essential characteristics, allowing for variation expected from the way it is propagated. Stability means essential characteristics stay unchanged after repeated propagation, or at the end of each cycle for a particular propagation cycle.

An extant variety (for example one notified under section 5 of the Seeds Act, 1966, a farmers' variety, or one in common knowledge or the public domain) is registered under section 15(2) within a specified period. It need meet only the criteria of distinctiveness, uniformity and stability specified in the regulations. Novelty is not required.

Section 29 then lists exclusions, and section 13 sets up the National Register of Plant Varieties, kept at the head office of the Registry under the control and management of the Authority. Each branch office keeps a copy.

Key rules to remember

Registrability of a new variety (s.15(1)): Registrable = Novel + Distinct + Uniform + Stable; All four criteria must be met for a new variety. The denomination must also pass s.15(4).
Novelty periods (s.15(3)(a)): India: not sold earlier than 1 year before filing. Abroad: trees or vines 6 years; other plants 4 years; Counted back from the date of filing. Sale or disposal by or with the breeder's consent for exploitation is what matters; trials do not count.
Extant variety (s.15(2)): Extant variety = DUS only (as per regulations), within a specified period; No novelty test. Extant varieties include those notified under the Seeds Act, 1966, farmers' varieties, common knowledge and public domain varieties.
Distinctness (s.15(3)(b)): Clearly distinguishable by at least one essential characteristic from any variety of common knowledge in any country; A variety applied for in a convention country becomes common knowledge from that application date if it leads to a grant or entry in the official register.
Denomination bars (s.15(4)): No registration if denomination: cannot identify the variety; is only figures; misleads or confuses; is not different from existing denominations; deceives the public; hurts religious sentiments; is barred under the Emblems and Names Act, 1950; or is wholly or partly a geographical name; Proviso: a geographical name may be registered if the Registrar considers its use an honest use.
Exclusions (s.29): s.29(1) public order, morality, life and health, environment; s.29(2) only notified genera or species; s.29(3) harmful technology including GURT and terminator technology; s.29(5) deleted genera or species get no protection; s.29(4): the Central Government cannot delete a genus or species from the notified list except in the public interest.
National Register (s.13): Register at head office of Registry; managed by the Authority; copy at each branch office; Entries: names of registered varieties, breeders' names and addresses, breeders' rights, denomination particulars, seed or propagating material with salient features, and other prescribed matters.

How to solve Registrable Varieties and Exclusions from Protection questions

Use this order for any question on registrability, exclusions or the Register. It follows the provision, analysis, conclusion pattern the examiner expects.

1Classify the variety from the facts: new variety, extant variety, farmers' variety or essentially derived variety. This decides which tests apply.
2Check whether the genus or species is notified under section 29(2). For other than extant and farmers' varieties, only notified genera or species can be registered.
3Apply the section 29(1) and 29(3) exclusions: harm to public order, morality, life, health or environment, or any harmful technology such as terminator technology.
4For a new variety, test novelty with the correct period (1 year in India; 6 years for trees or vines abroad; 4 years for others abroad). Note any trials or common knowledge.
5Test distinctness, uniformity and stability one by one using the statutory wording. For an extant variety, test only DUS.
6Test the denomination against each ground in section 15(4), including the geographical name proviso.
7State the consequence: registration is allowed or refused, and registered particulars are entered in the National Register under section 13. Give a clear one-line conclusion.

Quickest way: Four-gate check plus exclusion screen

When to use it: Short-answer or case questions where you have limited time and need a structured answer in a few minutes.

Write the label: new or extant variety.
Screen first: s.29 exclusion or unnotified species? If yes, conclude refusal and stop.
Run NDUS for new varieties (DUS for extant) and quote the key test words and periods.
Check the denomination in one line against s.15(4).
Conclude, and add that registration leads to entry in the National Register under s.13.

Common mistakes in Registrable Varieties and Exclusions from Protection

Applying the novelty test to extant varieties.
Students memorise NDUS as one block and forget that section 15(2) asks only for DUS for extant varieties.
Fix: Link extant variety to DUS only, under regulations, within a specified period.
Mixing up the novelty periods, for example saying four years in India.
The three periods (1, 6, 4) sound alike and are easy to swap.
Fix: Remember: India is one year; abroad is four years, six for trees and vines.
Treating novelty as 'never published or known anywhere'.
Students import the patent idea of novelty.
Fix: Plant variety novelty is about commercial sale or disposal by or with breeder's consent. Trials and common knowledge from other sources do not defeat it.
Stating that section 29 bans all varieties with biotechnology.
Students overstate the terminator technology rule.
Fix: Section 29(3) bars varieties involving technology that is injurious to the life or health of humans, animals or plants. The Explanation says such technology includes genetic use restriction technology and terminator technology.
Ignoring the denomination test and the honest-use proviso.
The focus stays on NDUS, so the section 15(4) grounds are skipped.
Fix: Always add a denomination line. Remember that a geographical name is barred unless the Registrar finds honest use.
Saying the Register is kept at every office as the master copy.
Students blur head office and branch office roles.
Fix: The Register is kept at the head office of the Registry under the Authority's control. Each branch office keeps a copy.

Worked examples

Example 1

Green Fields Seeds Ltd., Pune, developed a new rice variety and sold its seed in India on 1 March 2026 with its own consent. It files an application for registration on 10 January 2027. Is the variety novel? Would your answer change if the first sale had been in India on 1 March 2025?

Show the solution

Provision: under section 15(3)(a)(i), a new variety is novel if, at the filing date, its propagating or harvested material has not been sold or disposed of by or with the breeder's consent for exploitation in India earlier than one year before filing.
Analysis, first case: the sale on 1 March 2026 is about ten months before the filing date of 10 January 2027. That is within one year, so it is not earlier than one year before filing.
So the sale does not defeat novelty, and the variety can still satisfy the novelty test.
Analysis, second case: a sale on 1 March 2025 is about ten months more than one year before 10 January 2027. That is earlier than one year before filing.
The sale then defeats novelty, and the variety cannot be registered as a new variety.

Answer: In the first case the variety is novel because the Indian sale was within one year before filing. In the second case it is not novel, because the Indian sale was earlier than one year before the filing date.

Example 2

Agri Genetics Pvt. Ltd. applies to register a cotton variety developed with a technology that makes the plant's seeds sterile in the next generation. Advise whether it can be registered, and state what happens to a variety that is registered.

Show the solution

Provision: section 29(3) says no variety involving any technology injurious to the life or health of human beings, animals or plants shall be registered, notwithstanding section 29(2) and sections 15(1) and (2).
The Explanation says 'any technology' includes genetic use restriction technology and terminator technology.
Analysis: seed sterility in the next generation is the feature of genetic use restriction or terminator technology. Even if the variety passes the NDUS tests under section 15, section 29(3) overrides them.
Section 29(1) is a further ground if commercial exploitation must be prevented to protect public order, morality, human, animal and plant life and health or the environment.
Consequence for a registered variety: the facts do not involve registration, so the Register under section 13 would show no entry for this variety.
Conclusion: registration must be refused.

Answer: The variety cannot be registered. Section 29(3) overrides the NDUS criteria for varieties involving injurious technology, and its Explanation expressly includes genetic use restriction technology and terminator technology. Because registration is refused, no entry for the variety is made in the National Register of Plant Varieties.

Exam tips

Write the section numbers: 15 for criteria, 29 for exclusions, 13 for the Register. Examiners reward correct section references only when you are sure of them.
In case questions, always date-check the novelty periods against the filing date, and say whether the variety was sold in India or outside.
State the extant variety rule explicitly: DUS under regulations, within a specified period. This is a frequent differentiator.
For 'explain section 29' questions, cover all five sub-sections briefly, including the public interest limit on deleting genera or species.
Close with one sentence on the National Register contents when the question asks about registration consequences.

Practice questions from Protection of Plant Varieties

Registrable Varieties and Exclusions from Protection: frequently asked questions

What is the DUS test in plant variety protection?

DUS stands for distinctness, uniformity and stability, defined in section 15(3)(b) to (d). A new variety must also be novel, so the full set is NDUS. An extant variety needs only DUS as per the regulations.

What is an extant variety and how is it registered?

An extant variety is one available in India that is notified under section 5 of the Seeds Act, 1966, is a farmers' variety, is a variety of common knowledge, or is otherwise in the public domain. Under section 15(2) it is registered within a specified period if it meets the DUS criteria specified in the regulations.

What does section 29 of the PPVFR Act say?

Section 29 excludes certain varieties. Registration is barred where prevention of commercial exploitation is necessary to protect public order, morality, life and health or the environment. Only notified genera or species can be registered (other than extant and farmers' varieties). Varieties involving injurious technology, including terminator technology, cannot be registered.

What is recorded in the National Register of Plant Varieties?

Under section 13, the Register records the names of all registered varieties, the names and addresses of their breeders, the breeders' rights, the denomination particulars, the seed or propagating material with salient features, and other prescribed matters. It is kept at the head office of the Registry under the Authority, with a copy at each branch office.
