Tissue Culture Laboratory

Solan has invested in its own Tissue Culture laboratory for the specific purpose of production of potato plantlets to meet its mini tuber order requirements as placed by Australian potato seed producers. The laboratory is able to hold up to 70 000 plantlets at any one time prior to release to the general nursery greenhouse.

The laboratory receives potato tissue either directly from The Department of Agriculture’s Post Entry Quarantine Facility or other approved tissue culture laboratories. Upon receipt plantlets are assessed and logged into Solan’s system for either storage as backup cultivar stock for PBR Clients and or production of mini tubers.

The process of tissue culture involves cutting plantlets into micro plantlets under sterile conditions to rapidly increase plant numbers. These new plants are then planted into Solan’s general nursery facility where our mini tubers are produced. This process rapidly generates significant volumes of a variety for the marketplace whilst maintaining the genetic integrity of varieties, ensuring producers receive consistent varietal characteristics and quality in their mini tubers. Micro plants develop a root system and top in the laboratory over a period of 3 weeks after which they are sent out for planting.

Within the laboratory are refrigerated cabinets dedicated to the storage of our Genetic Potato Tissue. All mother stock is held isolated within this Genetic Resource Centre under fully monitored conditions to ensure high quality cultivar tissue and health for production purposes.

The majority of Potato Cultivars within our Genetic Resource Centre are held with agreements covered under Australian Plant Breeders Rights. The remaining cultivars are public varieties which are available for production of potato mini tubers and require no prior authorization to access.

Solan produces its own growth media for storage of all invitro material within its genetic collection, including production tubs for order generation. A major component of the media solution is water. All water used in the preparation of growth media is derived from filtering rainwater via a demineralising system to a holding tank for use as required. This process results in a very pure quality water, free of salts and minerals that could negatively effect plant growth. Once all components for growth media are combined it is dispensed into appropriate vessels and autoclaved to sterilize.
