Optimization of aeroponic technology for future integration in quality potato seed production systems in tropical environments

Virus and soil borne pathogens negatively impact on the production of potatoes in tropical highland and sub-tropical environments, limiting supply of an increasingly popular and important vegetable in these regions.
It is common for latent disease infected seed tubers or field grown cuttings to be used as potato planting material.
We utilised an International Potato Centre technique, using aeroponic technology, to produce low cost mini-tubers in tropical areas.
The system has been optimised for increased effectiveness in tropical areas.
High numbers of seed tubers of cultivar Sebago (630) and Nicola per m² (>900) were obtained in the first generation, and the system is capable of producing five crops of standard cultivars in every two years.
Initial results indicate that quality seed could be produced by nurseries and farmers, therefore contributing to the minimisation of soil borne diseases in an integrated management plan.
This technology reduces seed production costs, benefiting seed and potato growers.
