Summit Plant Labs

Summit Plant Laboratories, Inc. (SPLI) offers potato clean stock, certified seed potato minitubers, tissue culture propagation, seed health testing, and plant pathology services to breeders, seed producers, greenhouse operators, and field crop farmers. Its potato activities are concentrated in the early phases of the seed potato supply chain, generating disease-indexed plant material and generation-zero minitubers for further multiplication and commercial potato production. The firm also owns patented potato varieties and offers breeding and genetic repository services.

Summit Plant Laboratories was founded in 1987 in Fort Collins, Colorado, and is an independent, family-owned, and locally run plant laboratory. The firm specialises in wholesale micropropagation, clean-stock manufacturing, and seed health testing, and its headquarters, laboratory, and greenhouse are all in Fort Collins. Its core crop concentration is on potatoes, hops, and mint, but its tissue culture skills extend to other crops and plant initiatives.

Summit Plant Laboratories combines tissue culture and greenhouse production technologies to create clean seed stocks. Its potato minitubers are defined as verified, generation-zero nuclear seed grown from tissue-cultured material in a controlled greenhouse environment. The company's in-vitro plant library comprises a large number of potato cultivars, with more types accessible based on production requirements and advance notice.
