At The Rocinante Lab, we integrate cutting-edge technologies, including molecular genomics, phenomics, physiology, pathology, statistics, and breeding, to develop innovative strategies for creating superior crop varieties. Our research emphasizes genomic prediction and selection, association mapping, and the characterization of allelic diversity.
Expanding our global perspective, leverage advanced machine learning and artificial intelligence
methodologies to enhance the accuracy and efficiency of our breeding programs. By focusing on optimizing the selection and mating of individuals, we aim to accelerate genetic gains and improve trait performance across diverse environments.
Our work encompasses a variety of crops, including small grains, sunflower, and berries, reflecting our commitment to addressing global food security challenges through interdisciplinary and data-driven approaches.

There have been many scientific reports evaluating models and accuracy of GAB in plant breeding programs. However, the information on how, when, and why to apply GAB tools in real plant breeding programs is scarce. The main reason for this lack of information is that most plant breeding programs are private, and also GAB applications are in relatively new tools. Here, we aim to apply knowledge driven genomic prediction tools from a empirical public breeding program that will help to deliver general guideline applications of this technology.
Building on previously developed genomic tools, this project aims to revolutionize our understanding of wheat-Septoria tritici blotch interactions. We're validating predictive models through controlled greenhouse challenges of 200 wheat lines with 100 pathogen isolates, then extending to field conditions with fresh Spanish isolates. Through genome-wide association studies, we're pinpointing resistance loci and developing forecasting tools for pathogen aggressiveness. Our goal is rapid knowledge transfer to breeders and farmers through workshops, training sessions, and publications. Impact: Enabling breeders to develop durable disease resistance by understanding the genetic architecture of both host and pathogen.
This project addresses the growing demand for sustainable, high-value spelt wheat. Through comprehensive stakeholder engagement with farmers and agri-food industry, we've identified three critical needs: low-input high-yield varieties for farmers, nutritious organic grains for food processors, and promotion of soil health and biodiversity. We're conducting varietal assessments, genotype-by-environment studies, and genome-wide association analyses to develop resilient spelt strains that deliver economic, environmental, and social benefits.
In colaboration with University of Cordoba we are aiming to implemente genomic tools to improve genetic gain on traditional olive tree breeding. A fundamental challenge in breeding is balancing genetic gain against diversity loss. How do we achieve maximum improvement while preserving variation for future progress? Our OGM research leverages stochastic simulations and real-world implementations to support breeders in selecting superior crosses. This approach accelerates development of resilient, high-yielding crops while maintaining long-term genetic diversity—essential for sustained breeding progress. Paradigm shift: Moving from selecting individual plants to optimizing entire mating strategies for multi-generational impact.
This innovative partnership applies cutting-edge genomic selection to fast-track blueberry cultivar development for water stress and warm climates. Over three breeding cycles, we're phenotyping 200-400 seedlings annually for key traits (phenology, vigor, fruit quality) while conducting high-throughput genotyping. Our iteratively refined predictive models enable early identification of superior genotypes, drastically reducing field trial requirements and accelerating breeding cycles. Innovation: Demonstrating genomic selection's power beyond traditional field crops—expanding to high-value horticultural species.
Wheat (the second most important crop worldwide) yields are not currently increasing at comparable rates to those achieved in previous decades. Exploitation of the full range of available genetic resources (pre-breeding) could help develop new varies that will be needed in the future. The emergent technologies based on Artificial Intelligence and Machine learning are interesting tools to handle the huge volumes of genotypic and phenotypic data that are generated from agronomic and biological experiments. The aim of this PhD project is to develop statistical and programming tools to exploit and decode the hidden patterns underlying data and apply this knowledge on real breeding problems in both academical and industrial fields.
This project aims to provide a benchmark guideline on genomic assisted breeding for Syngenta sunflowerbreeding program by building tools and models that augment current practices capitalizing on advances in genomics, phenomics, imaging technologies, and machine learning.
