The National Seed Institute (INASE) has introduced significant changes to the registration process for new plant varieties through Resolution 49/2025.
Registration in the National Cultivar Registry (RNC) is mandatory for all seed varieties that are made available to the public or delivered to users with an identifying label. This registry enables the commercialization of these varieties.
The main change is the elimination of Comparative Yield Test (CYT), a measure that simplifies and accelerates the incorporation of new varieties into the market.
What Were Comparative Yield Tests (CYT)?
CYTs were a mandatory requirement for registering new cultivars in the RNC. They applied to species subject to mandatory inspection, such as cotton, rice, sunflower, corn, soybean, sorghum, bread wheat, durum wheat, barley, alfalfa, and potatoes, among others.
These tests were used to assess the agronomic performance of new varieties in comparison to already registered cultivars. They evaluated yield, resistance to diseases, pests, and adverse climatic conditions, as well as other relevant agronomic factors that influence crop productivity and stability.
The process was lengthy and costly, as tests could take between two and three years to be completed, delaying the introduction of new varieties to the market. With the elimination of CYTs, cultivar registration and commercialization are expected to become more agile.
What Is the New Registration Process?
With Resolution 49/2025, the procedure for registering new varieties has been simplified. Below is a summary of the main requirements and necessary documentation/information:
- Registration Requirements:
- The registration application must be submitted by an individual or legal entity registered in the National Register of Seed Trade and Control (RNCyFS) under the breeder (A) and/or introducer (B) category.
- For foreign applicants, the Legal Representative must fulfill the registration requirement in the RNCyFS.
- Required Documentation:
- Sworn Statement Registration Application Form.
- Information on the Cultivar (details of the applicant, sponsoring agronomist, and the establishment where the cultivar was developed).
- Description of the variety.
- Procedure for maintaining varietal purity (who performs it and how it is carried out).
- Breeding history of the variety.
- If the variety is genetically modified, information and documentation on the incorporated transgenic event.
- Document proving the legal capacity of the representative to act on behalf of the applicant.
- Document signed by the sponsoring agronomist endorsing the submitted technical information.
All documentation must be submitted in Spanish or accompanied by an official translation by a Certified Public Translator and corresponding legalizations.
The procedure is carried out through the Plataforma de Tramites a Distancia (TAD) – Argentina’s online platform for public procedures.
With this simplification, INASE aims to promote innovation in the seed industry, facilitating the development and commercialization of new varieties.
