2D GWAS in Potato Breeding – HZPC

In collaboration with BionomeeX

HZPC is a company specialized in the development and commercialization of potato varieties tailored to economic, societal, and environmental requirements.
They create varieties adapted for fresh markets (firm flesh, mashing, frying) as well as for industrial uses (fries, chips, etc.).

Genetic Analysis Through 2D GWAS

In collaboration with BionomeeX, we apply 2D GWAS to analyze genetic data from different potato varieties.
The goal is to identify interactions between genetic variants that influence key agronomic traits, including:

• 🛡️ Disease resistance

• 🥔 Flesh quality and texture

• 🌦️ Adaptation to regional climates

• ⚙️ Industrial productivity (yield for fries, chips, mash)

The 2D GWAS approach goes beyond classical analyses by detecting epistatic interactions between variants — revealing gene combinations that affect traits of interest and explaining part of the “missing heritability” in complex traits.

From Data to Breeding Innovation

This enables HZPC and BionomeeX to:

• 🔍 Identify optimized genetic profiles for new variety selection

• 📈 Develop more precise and predictive breeding strategies

• ⚡ Accelerate the creation of varieties adapted to market needs and environmental challenges

Toward a Smarter Agriculture

This project demonstrates how 2D GWAS can transform plant breeding by providing a detailed understanding of the complex relationships between genes and phenotypes.

It contributes to addressing modern agricultural and industrial challenges, paving the way for sustainable, data-driven, and efficient crop development.
