Quality seed material is the basis for successful potato growing. The deficiencies of planting material are difficult, and often impossible, to correct with agrotechnical measures.
If you notice that every year there are more and more small potatoes in the total crop volume, tubers acquire an atypical shape, yield decreases and product quality deteriorates, it is safe to assume that the problem lies in the degeneration of the potato and the aging of the variety.
Signs and consequences of seed degeneration
As you know, potatoes are an annual plant that reproduces vegetatively - tubers. With each subsequent reproduction, the quantitative and qualitative indicators of yields decrease, diseases gradually accumulate.
Degeneration of potatoes to one degree or another is observed almost everywhere, but it is especially pronounced in the southern regions. If in the north and in the middle zone of our country the damage from viral diseases of the potato is determined at 10-20%, in the south it reaches 50-70% and more.
Experts call viral diseases the main cause of potato degeneration. Most often, viruses are transmitted from diseased plants by healthy sucking insects (aphids, leafhoppers), although spread is possible by contact. Through the planting material, viruses are transmitted to the next generation of plants - the tubers reproduce, and the infection accumulates with each new year of use. The harmfulness of viruses depends on their composition, concentration in plants, characteristics of the potato variety (its resistance) and external conditions.
The accumulation of viral infection often causes deviations from varietal traits. Tubers become elongated, smaller, in red-skinned varieties, a paler color may be observed, etc.). When infected tubers germinate, filamentous sprouts appear.
Viral diseases of potatoes lead to weakening of photosynthesis and transpiration of plants, destruction of chlorophyll in the leaves. Plants become more susceptible to fungal diseases. Less dry matter, starch and ascorbic acid accumulate in tubers, which leads to a significant deterioration in their taste. Indicators of field germination also decrease.
Avoiding the problems listed above is possible only by regular renewal of seeds, relying on high-quality products of high quality, grown in areas favorable for seed growing by proven originators and breeders.
Buyer's guide
- When choosing seeds, it is important to pay attention to whether the seller has the necessary package of documents: the batch considered for purchase must be certified and have a certificate of conformity. Only in this case can one expect that the assessment of its "pedigree" was carried out by accredited specialists, the health of seeds at the stage of growth in the field was constantly monitored (approbation was carried out), and before sale the products were checked for compliance with the declared class, variety and the presence of seed potential in absence / limited presence of pathogens).
- Seed potatoes of the Elite and RS-1 classes are best purchased from the originators of the variety or from producers who have a sublicense agreement for the right to produce and sell a certain variety, class, in the agreed territory (holders of a patent for the variety). In this case, the buyer receives a batch of a reliable variety with a transparent history.
Choosing modern varieties
The NORIKA company has been known in the professional market since 1990. Over the past period, the company's breeders have created dozens of highly productive varieties with developed adaptive properties, resistance to viral diseases and other potato diseases; characterized by stability of quality, excellent keeping quality, having excellent taste.
And this work continues: annually in NORIKA laboratories about 400 crosses are carried out: scientists solve urgent problems of obtaining new varieties with popular consumer qualities (with a specific tuber shape, color of pulp and peel, etc.), high yield potential and resistance to various pathogens diseases.
Today's breeding points the way to the future, as the challenge of this science is to meet the changing demands of the market.
At the moment, the NORIKA line includes more than 70 varieties of potatoes of its own selection, intended for sale on the national and international markets.
Quality comes first
LLC "NORIKA-SLAVIA" - the exclusive representative of the company NORIKA on the territory of the Russian Federation - is engaged in the supply of elite seed material from Germany. Also, since 2013, the company has been developing a direction for seed multiplication in Russia, having completely localized the entire production process in our country, which makes it possible to obtain high-quality seed material at Russian market prices. Original and elite seeds are grown in the Arkhangelsk, Vologda regions, as well as in the north of the Moscow region.
The company's seed growers use a special approach to their work. The requirements for the selection of fields with good spatial isolation are very strictly observed; crop rotation schemes; rules governing planting density, timing and number of chemical treatments and phyto-cleanings, disease vector control work. The professional organization of the harvesting and storage of seed potatoes is essential.
The resulting crop undergoes a thorough multi-stage check and is sent for sale only after receiving confirmation of the absence (limited by GOST tolerances of the minimum presence) of a viral, bacterial, fungal infection in the tubers.
This season LLC "NORIKA-SLAVIA" offers domestic customers seed potatoes of varieties GALA, VEGA, VENDI, FIDELIA, Inar, MERLOT, SAFIA, Estrella and others, Russian and foreign production.
You can get detailed advice on the advantages and features of growing each of them, as well as order a batch of the required volume, by phone or through the feedback form on the website.
