Harnessing Pangenome Analysis to Accelerate Genetic Gain in Agricultural Breeding Programs
Unlock the full potential of your breeding populations with KhufuPAN™ - the most comprehensive pangenome analysis platform for precision agriculture.
Redefining Trait Discovery
As the global agricultural sector responds to challenges such as climate change, population growth, and resource sustainability, the need for advanced genetic tools in crop and livestock improvement has never been more urgent.
Traditional reference-based genome analysis, long a cornerstone of breeding programs, is increasingly limited in scope and often fails to capture critical genetic variation.
To overcome these limitations, HudsonAlpha Institute for Biotechnology has developed KhufuPAN™, a high-resolution pangenome analysis platform. KhufuPAN enables breeders to comprehensively analyze genomic variation across founder populations, offering unprecedented insight into genetic diversity and uncovering previously inaccessible trait-associated variants.
The Genomic Bottleneck in Modern Breeding Programs
The application of genomic tools in agriculture has significantly enhanced breeders' ability to select for favorable traits. By identifying regions of the genome associated with characteristics such as yield, resilience, nutrient use efficiency, or disease resistance, breeders can make more informed selection decisions.
KhufuPAN: A Pangenomic Framework for Precision Breeding
HudsonAlpha's KhufuPAN platform delivers a graph-based pangenome, a comprehensive representation of all DNA sequences within a species, including both core and accessory genomic content.
Complete Genomic View
Captures structural variation, SNPs, and presence-absence variants across founder lines for unprecedented insight into genetic diversity.
Precision Detection
Identifies genetic variants not present in standard reference genomes and uncovers trait-associated markers in complex and variable regions, improving alignment and variant calling accuracy across diverse germplasm.
Actionable Insights
Provides customizable reports tailored to inform selection, mating, and advancement decisions with improved accuracy. These insights empower breeders to make data-driven decisions, optimize breeding strategies, and enhance genetic gain.
Built using the streamlined Khufu data analysis framework developed by Dr. Josh Clevenger and his team, KhufuPAN identifies and integrates structural variation, single-nucleotide polymorphisms, and presence-absence variants across founder lines.
Advantages over Reference-Based Approaches
Reference genomes provide a standardized scaffold for genetic comparisons, but they fall short in representing the total variation present in a species. KhufuPAN has been designed to overcome key limitations faced by traditional genomic tools.
Traditional vs. KhufuPAN Approach
Traditional Reference Approach
- Single sequence for alignment
- Misses structural variation
- Ignores accessory genes
- Decreased variant calling accuracy
- Biased toward reference genotype
KhufuPAN Pangenome Approach
- Graph representation of all lines
- Captures insertions, deletions, inversions
- Includes complete genome content
- Improved alignment and detection
- Genotype-agnostic analysis
Applications in Founder Populations and Trait Discovery
The KhufuPAN platform is particularly valuable in breeding programs based on narrowly selected founder populations. Accessory genomic components (genes or genomic segments present in some individuals but absent from the reference) can play key roles in traits related to environmental stress, biotic resistance, or metabolic profile.
By including these in the pangenome graph, breeders gain a more complete view of their germplasm and can select parent lines or crosses that maximize the probability of retaining beneficial genetic elements.

Proven Results Across Global Breeding Programs
KhufuPAN has been successfully deployed in breeding programs for crops and animals across continents and climates.
In collaboration with the Groundnut Improvement Network for Africa, KhufuPAN was used to create a comprehensive pangenome resource representing founder lines from across the continent. This breakthrough work is improving local adaptations of peanut varieties, enhancing yield stability and resilience to climate challenges specific to African agricultural conditions.
Our pangenome graphs revealed previously hidden genetic variation associated with critical traits including fruit size, flavor profiles, and pathogen resistance. These discoveries are directly guiding targeted breeding decisions, resulting in more efficient selection processes and improved cultivar development timelines.
