Grape Variety Registration 2026: IMIDRA Assumes Genetic Analysis and What It Means for Breeders

Key data

If you develop, market, or intend to register a new grape variety in Spain, the technical examination process prior to registration has just changed hands operationally. The Ministry of Agriculture has formalized a management delegation agreement with IMIDRA so that this autonomous Madrid body assumes the molecular marker analysis that is essential before registering any variety in the official registers. The resolution was published in the BOE on 28 July 2026 and became effective that same day.

What does this regulation establish?

The agreement entrusts IMIDRA with the material execution of molecular marker analysis that MAPA needs to carry out technical examinations of grape varieties. These examinations are a mandatory prerequisite for registering varieties in two official registers:

• Register of Protected Varieties — for obtaining breeder's rights.
• Register of Commercial Varieties — to legally market seeds or reproductive material of the variety in Spain.

The specific scope of the delegation covers the following tasks:

• Selection of comparator varieties for technical examinations.
• Detection of synonymies (identifying whether a presented variety already exists under another name).
• Control of varieties present in the market.

IMIDRA provides its El Encín germplasm bank, with more than 3,700 accessions and 7,000 genotypes, and is accredited by the Community Plant Variety Office (CPVO), which ensures that the analyses are also valid at the European level.

A key point for applicants: the ownership of competence and responsibility for administrative acts remains with MAPA. IMIDRA executes the analyses, but the registration resolutions continue to be signed by the Ministry.

Economic and operational impact

This agreement does not introduce new fees or direct costs for registration applicants. Its impact is mainly operational and efficiency-related:

• Reduction of timelines: By centralizing analyses in a specialized body with its own infrastructure (El Encín germplasm bank), external dependencies that could extend technical examinations are eliminated.
• Greater technical reliability: IMIDRA is accredited by the CPVO, which reduces the risk of technical challenges in the registration process.
• Early detection of synonymies: If your variety already exists under another name in the germplasm bank, you will know before investing in the complete registration process, avoiding unnecessary costs.
• Market control: The delegation includes control of varieties in the market, which may affect marketers operating with unregistered or misidentified varieties.

Who does it affect?

• Grape variety breeders seeking protection of their rights in the Register of Protected Varieties.
• Nurseries and marketers needing to register a variety in the Register of Commercial Varieties to legally sell reproductive material.
• Wineries and wine groups developing new proprietary varieties or working with unregistered niche varieties.
• Plant breeding companies with clonal or varietal selection programs in grapes.
• Importers of plant material intending to introduce grape varieties from other countries into Spain and requiring prior registration.

Practical example

A Rioja winery has developed a Garnacha variety with differentiated organoleptic characteristics over ten years and wants to protect it through the Register of Protected Varieties to obtain exclusive breeder's rights.

With the new agreement, the process works as follows:

1. The winery submits its registration application to MAPA.
2. MAPA delegates to IMIDRA the performance of molecular marker analysis on the presented variety.
3. IMIDRA compares the variety with more than 3,700 accessions and 7,000 genotypes from the El Encín germplasm bank to verify that it does not already exist as a synonym of another registered variety.
4. IMIDRA selects the appropriate comparator varieties for the technical examination of distinctness, uniformity and stability (DUS).
5. MAPA, with IMIDRA's results, issues the registration resolution. Administrative responsibility is entirely with the Ministry.

The result for the winery: a technically more robust and potentially faster process, backed by a body accredited by the Community Plant Variety Office.

What should companies do now?

1. Review if you have grape varieties pending registration: If you have applications in progress or planned, verify that your file is properly documented for technical examination, since molecular analyses are now executed by IMIDRA.
2. Check for possible synonymies before applying: Given that IMIDRA has the El Encín germplasm bank with more than 3,700 accessions, consider consulting beforehand whether your variety could match one already cataloged. You will avoid costs and delays.
3. Verify that the plant material you market is properly registered: The delegation includes market variety control. If you market grape reproductive material, ensure that varieties are registered in the Register of Commercial Varieties.
4. Update your internal varietal R&D procedures: If you have plant breeding programs in grapes, incorporate into your roadmap the step of molecular marker analysis through IMIDRA as part of the official registration process.
5. Consult with MAPA on the status of pending applications: If you have registration applications submitted before 28 July 2026, confirm with the General Directorate of Agricultural Production and Markets how this agreement affects your specific file.
