Space spin-off with Russian mini-spud
Space spin-off with Russian mini-spud

TECHNOLOGY from the Russian space programme is being used to produce mini-seed tubers and accelerate the variety multiplication process. New markets for UK breeders could result.
The technique, developed so cosmonauts could grow some of their own food in the Mir space station, grows minitubers using hydroponics in a controlled environment.
"The big advantage is that the mini-tubers are completely disease-free and are produced without using hormones or other growth promoters," says Moscow-based DokaGenes Alan Parker. With three crops a year a rapid build up of seed is possible and seed producers can respond quickly to changes in grower specification requirements, he says.
Test-tube grown mini-plants are planted out onto the Potato Tree, a mobile unit developed for agricultural use by the firm. In 40 days the first 20-25mm (0.8-1.0 in) tubers, weighing 5-7g (0.18-0.25oz) can be harvested. The crop is fed through a special hydroponic medium supported on a perforated mat. The tubers grow through the mat and can be picked from below.
Each plant produces 40-50 tiny tubers, which after three months dormancy can be woken up and planted out in the field. Each tuber is packed with power and grows vigorously into a strong plant capable of high yields of first generation seed, he says.
The Russian company has capacity to produce 2.5m minitubers a year, and is expanding rapidly.
"Last year we handled 27 different varieties, this year we have 40," said Mr Parker. "Only four are native Russian types. The rest are either brand-new, or tried-and-tested types from UK breeders."
At 3m hectares (7.4m acres) the Russian potato crop has huge, untapped seed potential, concludes Mr Parker.
The seed potato market in Russia has huge potential, as total plantings top 3mha (7.4m acres) notes Mr Parker, a point he hopes DokaGene can exploit to the full.
