A flexible, high-throughput solution for real-world seed and plant health programs
Genetic purity testing is essential for confirming hybrid integrity, monitoring production quality, and supporting long-term breeding strategies. But as crop portfolios expand, many standard testing methods—like SSR or KASP panels—struggle to keep up with the demands of resolution, throughput, and scalability.
CSP Labs’ Genotyping by Amplicon Sequencing (GBAS) offers a practical alternative. It delivers robust, cost-effective results using targeted sequencing that bridges the gap between low-resolution tests and expensive whole-genome platforms. Each panel includes 50 or more informative SNP markers and can process thousands of samples in parallel.
Applications range from hybrid purity confirmation and contamination detection to marker-assisted breeding and varietal fingerprinting. For programs that need clarity without the overhead of complex genomic tools, GBAS is a reliable fit.
How Our Panels Are Built
Each GBAS panel begins with the evaluation of 100–200 potential SNP markers across parental or inbred lines. From there, we select markers that are homozygous, PCR-efficient, and highly differentiable. This ensures each panel provides strong, genome-wide coverage and high discriminatory power that are designed to evolve alongside your testing goals.
Panels are available for a growing list of crops, and we also offer custom development based on your breeding lines or traits of interest.

Real-World Results, Backed by AVITI™
In crops like sunflower, previous testing methods often failed to clearly distinguish between parent lines, leading to ambiguous results and unnecessary retesting. By leveraging the high-resolution power of AVITI™ sequencing, CSP Labs developed a GBAS panel that delivered consistent, reliable separation between varieties—eliminating the uncertainty that plagued earlier approaches.
This level of clarity isn’t limited to sunflower. For cucumber and pepper, GBAS outperformed legacy KASP methods by providing cleaner, more definitive results across complex genetic material.
The AVITI™ system plays a central role in making this possible. Its high Q30 scores and low cost per base enable large sample batches to be processed quickly without sacrificing accuracy. Because GBAS generates direct, data-driven SNP calls rather than subjective visuals, results remain consistent across labs and technicians—bringing greater confidence to every test.
A Scalable Option for Every Operation
Whether you’re managing large-scale seed production or a focused breeding program, GBAS can be tailored to your workflow. Customers can choose from our validated crop panels or collaborate with our team to develop a custom panel built for their specific material.
If you’re looking for a smarter, more scalable way to approach genetic purity testing, GBAS brings the clarity, efficiency, and adaptability your program needs.
