Innovative technology to grow virus-free seed potato is embedded in the Company "hothouse"
There have been several studies of test potatoes grown in the gardens of the Omsk region, and came to a sad conclusion: almost one hundred percent of the infected three especially dangerous for this crop viruses — X, Y and S. Also potatoes sick for such a formidable cultural disease such as spindle tuber viroid (SWCC). Unfortunately, called viruses circulate as active in the industrial potato. Perhaps only a few percent of infected tubers less. Meanwhile replaced varieties are not guarantees high yields, are new proposals potato breeders with high field resistance to viruses. Such potatoes may be grown for 7-8 years without fear of infection of tubers and yield decrease. Having bought a new hybrid seed potato varieties in the Netherlands and Germany, ZAO "hothouse" came out on the highest yields in the region and the qualitative characteristics of this beloved Siberians vegetable crops.
Came the question: why do not themselves manufacture quality seeds not only for the needs of the "hothouse", but for all the companies involved in the production of marketable potatoes? And gardeners, gardeners, I think, would be willing to purchase the seeds to ensure high yield, good taste, keeping quality.
For the production of seed potatoes has been selected advanced technology that allows you to take advantage of technological developments JSC "Greenhouse" and artificial lighting. Because of this Company "hothouse" is engaged in growing seed potatoes in early November, when daylight is only seven or eight hours, while the potatoes to grow in natural conditions, sunlight, daylight requires a minimum of 12 hours. The meaning of the start of the cycle in November — an additional antiviral prophylaxis. Many diseases infect potato insects. When it's late autumn, this way possible infection of potato viruses is reduced to almost zero.
In the first stage microplants grown potatoes. But it does not happen on the basis of "hothouse", and at the Moscow Institute of them. AG Lorch, in a specially equipped laboratory. To note, the term "apical meristem" denotes a group of cells in the apical buds plants. Under the microscope cells meristem isolate and placed in a tube with a special nutrient medium. After three or four months of them grow microplants.
Exactly the tube and profit in 2010, following the order of "Greenhouse" Omsk on the ground. Here they are again assayed for the presence of viruses, and then planted in pots. When microplants grew up with them in the axillary areas were also cut off shoots, shoots formed from cuttings that were seated in the cassette.
By the way, in the recent past, these tapes were used for growing seedlings of cabbage and cucumbers. And that came in handy in the new technology. Two weeks later, when the plants have grown and matured, their transplanted into pots and moved to another department of the greenhouse. After a certain period of time from the bushes in pots also shot shoots for cuttings. Then they were put in the drawer, and then — in the pots, where a bulk of the tubers.
Full technological cycle takes 4 years. Having minitubers, the second year they have planted in the open ground in order to grow the first field generation (not to be confused with a reproduction). A year later, disembark the tubers of the first generation — get super super elite. Disembark her — grows super-elite. It will be the main item on the market of seed potatoes.
Despite little experience using innovative technology to ZAO "hothouse" concluded the need to optimize the production of super-elite. Namely obtaining mini tubers and to connect the first field in the generation cycle. To do this, build a laboratory for micropropagation, to the very microplants in tubes that are purchased at the Moscow Institute of them. AG Lorch, to make at home. During the summer, many times they multiply, and in February, based on them to get a mini-tubers. As a result, the tubers will have time before the summer pass the required period of rest, and we'll be able to drop them off in the open ground for the production of the first field generation. Due to this two super-elite of the growing cycle will take only a year. But in general, the production of virus-free seed potatoes — three years instead of four proposed by the authors of innovative technology.
