We eliminate the risks and variables of commercial cultivation by providing our customers with verified, stable genetics and vigorous, disease-free clones.




Leading-edge technology for cultivar and pathogen identification for growers, breeders, and nurseries.



Our experienced team has been focused on perfecting plant propagation for decades. 3 Rivers Biotech has tissue culture protocols for over 1,000 different plant species that we utilize to bring innovation to the agricultural industry.

The Pacific Northwest is our home, but we ship premium tissue cultured plants all over the US and world. From Washington to Florida, we’re here to help farmers and late-stage nurseries de-risk their operations, scale their production safely, and reap the benefits of clean starting material.

Almost every clonally-produced crop has moved to tissue culture plant starts for a reason. Plants that are starting disease-free tend to be highly vigorous throughout their life cycle and focus more energy on growth and secondary metabolite production, augmenting the performance of the crop and economic return.

We work with established breeders and plant varieties in every region of the US to ensure that our genetics will help you succeed where you grow.

How we add value
to our customers

Financial Performance

Stable genetics and vigorous, disease-free plants to maximize the value of the finished product (small berries, healthy vigorous tropicals)

Every plant is is derived from tissue culture, giving the piece of mind to know that all pathogens have been removed

Our process is highly scalable, allowing you to continually and sustainably grow your operations

Risk Mitigation

Clonal plants are consistent to avoid genetic variation of your valuable crop.

Reduce risk of crop failure and diminishment from pest and pathogen pressures.

Reduce chance of failing strict pesticide testing with clean, laboratory produced plants.

Pathogen Detection – Genie Lab

Plant pathogens can affect all plant tissues and wipe out entire operations. Many infections can go undetected in asymptomatic plants only to decimate crops in the later stages of growth, such as hop latent viroid (HLVd). The quickest and most sensitive method to test for pathogens is a genetic analysis known as polymerase chain reaction (PCR). Our pathogen detection service screens samples with PCR for unique genetic markers of fungal, bacterial, and viral cannabis pathogens to providing clean plants and peace of mind.

Currently, our lab provides accurate, high throughput pathogen testing on plant tissue for the agricultural and horticultural industries. We are expanding to other small fruits in the near future.

We perform an 11-virus panel, a foliar/bud-rot panel, a foliar/stem panel, a root-rot panel, a Fusarium panel, a Pythium panel, a Phytophthora panel, and a biocontrol agent panel test on plant tissue to find out what is affecting your plants.

Current turnaround time for testing samples is NEXT DAY in most cases – please contact us for an estimate

Cultivar Identification

Genetic markers capable of affordably and conclusively verifying strains based on genetic heritage have long been sought. To that end, we have developed a DNA fingerprinting platform providing the tools necessary to verify cultivar identity, determine a cultivar’s position within the a family tree, and test for undesirable mutations arising during clonal propagation.

We provide high throughput genetic identification to the horticultural industry.

Genotyping identifies a variety or group of closely related varieties (or strains) based on a piece of genetic code unique to that individual or group.

Varieties can slowly change over time (strain drift). The genetic markers we use have high mutation rates and serve as proxies to let a grower know when a strain needs to be re-introduced from a backup.

Plant Tissue Culture Services

Genetic Storage

Back up valuable production or seed lines. Off-site storage to secure germplasm in the event of a catastrophic facility failure (ex. Power outage, fire, HVAC failure). Clean copies provided back regularly.

Clean Mother Stock

Regular provision of clean mother stock to support internal propagation programs. Ensure quality performance using cuttings derived from tissue culture mother plants. De-risk operations by decreasing pathogen loads in facility nursery operations.
