Maize Trial Mapping – Bioleft 2025

During this campaign, we collaboratively carried out a participatory corn evaluation network, with trials distributed in Junín, Entre Ríos, and southeastern Córdoba. The network seeks to generate collective knowledge about the behavior of different corn varieties, focusing on materials developed by farmers and non-transgenic hybrids of interest for organic and agroecological production systems.

This mapping seeks to develop a comparative and participatory evaluation of corn varieties in diverse environments, including farmers’ fields—with different interests and strategies—and institutional properties, based on jointly constructed criteria. The goal is to learn and share how the materials behave under different conditions, thereby strengthening the processes of selection and participatory improvement.

The materials evaluated in this campaign are open-pollinated varieties (OPVs). Of the nine materials under evaluation, eight were developed by farmers, one by INTA (Amancay), one material was derived from a commercial hybrid, and two commercial hybrids were used as controls.

The objectives of this work are:

To strengthen farmers’ participatory breeding capacities.
To generate useful and contextualized information on the agronomic and productive behavior of different materials in various contexts.
To systematize and collectively share learning through a freely accessible collaborative document.

The following is a list of materials under evaluation:

ALBINCO: Material developed by Claudio Demo, producer from Río Cuarto. This material is evaluated in the town of Río Cuarto.
ADELIA: Material developed by Milton Vélez, producer from Río Cuarto. This material is evaluated in the town of Junín.
QUARENTÍN: Material reproduced by Claudio Demo, producer from Río Cuarto. This material is being evaluated in the towns of Río Cuarto, Lucas González (EERR), and Junín.
CHUCUL: Material developed by Claudio Demo, producer from Río Cuarto. This material is being evaluated in the towns of Río Cuarto, Lucas González (EERR), and Junín.
FRONTERIZO: Material developed by Claudio Demo, producer from Rio Cuarto, resulting from the combination of CHUCUL and QUARENTIN. This material is evaluated in the town of Rio Cuarto.
DORADO: Material developed by Claudio Demo, producer from Rio Cuarto. This material is evaluated in the town of Rio Cuarto
ROSILLO: Material developed by Claudio Demo, producer from Rio Cuarto, resulting from the combination of CHUCUL and ALBINCO. This material is evaluated in the town of Rio Cuarto.
ORIGINAL: Material developed by Enrico Cresta, producer from Rio Cuarto. This material is evaluated in the towns of Pergamino and Rio Cuarto.
Original C1: This variant of Original developed by Enrico, selected for quality, is evaluated in Pergamino and Rio IV. It is redder than Original and has good homogeneity.
