Letrah is pleased to offer Certified, pathogen free, seed potato chambers.

These chambers give the client the opportunity to sell very high quality

seed potato stock. The initial investment is very low and the return on

investment is very quick.

High quality seed potatos are a critically important component of economically

viable potato production operations. World-wide, major emphasis is currently

being placed on seed potato production systems that limit or reduce the number

of field multiplications or generations derrived originally from tissue culture plantlets.

Numerous field tests have confirmed the value of limiting the number of field

multiplications.

Another advantage of the limited field generation program is that it fosters rapid

multiplication of seed material. New cultivars can be rapidly multiplied to commercial seed

quantities and made available to seed growers.

Various systems are being used to produce pre-basic and basic seed for subsequent

field multiplication. The objective of the CETS Controlled Environment Potato Seed

Production System is to produce disease-free minitubers in adequate numbers; as rapidly

and as economically feasible. Tissue culture plantlets are used as the source material for

production of the astrotubers. Astrotubers are planted in the feild for the production

of the first generation, high quality, low pathogen, seed potatos.

Key features of the CETS production system:

- Production of potato nuclear stock in 60 days after planting of stem cuttings

- High quality, zero pathogen astrotubers.

- Allows up to 6 growth cycles per year.

- Utilizes controlled environment chambers that can be operated in any

climatic area during all seasons of the year.

- Unique software for programming optimal environmental conditions

for growth and development of potato plants.

- Smal space requirements for nuclear stock astrotuber production.

- High quality, disease-free astrotubers for initial field multiplication.

- Economical operation and production costs.

- New potato cultivars can be rapidly increased to commercial quantities.

- Suitable for organic producers or for genetically modified materials.
