Winter Wheat Genetic Resistance Screening for Sustainable Crop Production

Overview

This offering provides access to genetic resources screening capabilities focused on identifying winter wheat genotypes with natural resistance to fungal leaf, stem, and head diseases. The Research Plant Breeding Centre has over 40 years of experience breeding winter wheat varieties adapted to low fertilizer and pesticide application, making this service valuable for partners seeking to reduce chemical inputs while maintaining crop productivity.

By screening genetic collections of winter wheat from diverse geographic and genetic origins, valuable genotypes with genetic resistance to major fungal diseases can be identified. This approach addresses the growing need to adapt crops to new disease races and reduce chemical application across production regions.

Technical specifications

Screening capabilities:

• Field-based resistance assessment against harmful fungal diseases under natural conditions
• Laboratory analysis for molecular DNA markers linked to resistance traits
• Evaluation of physiological traits that may contribute to resistance mechanisms
• Genotype screening across winter wheat collections of different geographic and genetic origins
• Integration of field observations with molecular marker data to identify valuable genotypes

Key applications:

• Identifying genetic resistance sources for breeding programs
• Minimizing genetic erosion in seed, field, and in vitro collections
• Supporting sustainable agriculture through reduced pesticide dependency
• Developing varieties adapted to evolving disease pressures

Technology readiness level

The screening methodology is established and operational, built upon four decades of breeding research. Current validation includes comprehensive field analysis at the Research Plant Breeding Centre for resistance assessment and physiological trait evaluation, complemented by laboratory molecular marker analysis at the Laboratory of Ecological Genetics and Plant Biotechnology. The approach is ready for collaborative screening projects and applied breeding partnerships.
