Focus Areas
Plant breeding program consulting
Topcross Genomics provides strategic consulting for plant breeding programs, from early-stage population design to advanced selection schemes. Services include breeding program design, field trial planning, trait prioritization, and integration of molecular tools such as marker-assisted selection and genomic selection. With extensive experience in hemp and specialty crops, we help clients optimize breeding pipelines for yield, quality, disease resistance, and market-driven traits.
Custom bioinformatic analyses & pipeline development
We deliver custom bioinformatic analyses tailored to breeding and research objectives, including genome assembly, comparative genomics, variant discovery, trait mapping (QTL, GWAS, BSA), and population genetic analyses. Other common services include:
- Designing custom genotyping assays and molecular marker systems for trait tracking, quality control, and IP protection
- Developing user-friendly analysis pipelines in R, Unix, and Python for sequencing and phenotyping data
Training, Education, Technology Transfer
Topcross Genomics provides training and knowledge-transfer services to help teams effectively use modern breeding and genomics tools. This includes workshops and one-on-one training in data interpretation, experimental design, and applied genomics, as well as support for internal documentation and workflow adoption. We help organizations build in-house capacity by translating complex scientific methods into practical, usable systems for breeders, technicians, and R&D staff.
