At the end of December, the "Potato System" magazine organized a webinar dedicated to modern promising potato varieties. The webinar was attended by representatives of well-known breeding and seed companies operating in the Russian market. Each company told the audience about the benefits and features of the two varieties in their lineup.
We decided to keep this useful information for our readers by publishing it on the site as a series of articles.
The second material in this cycle is devoted to medium-early varieties. GALA и BALTIK ROUZ NORIKA selection. Speaker: Vladimir Chernetsov, agricultural manager of NORIKA-SLAVIA LLC.

Seed breeding company NORIKA (Germany) 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.
The exclusive representative of NORIKA on the territory of the Russian Federation is NORIKA-SLAVIA LLC. The company is engaged in the supply of elite seed material from Germany, and also develops the direction of seed multiplication in Russia, completely localizing the entire production process in our country.
35 varieties of NORIKA selection are currently included in the State Register of Breeding Achievements of Russia. Among them GALA, BALTIK ROUZ, VEGA, VENDI, FIDELIA, Inar, MERLOT, SAFIA, Estrella and others. Let us dwell on the first two in more detail.
GALA
Medium early variety for table use. High-yielding, number of tubers per bush: 20 to 40 pcs.
It is very popular in Russia, in Germany it is the standard in taste and keeping quality.
The tubers are round-oval, yellow peel, yellow flesh.
Tubers with very small eyes, resistant to mechanical damage. The variety is suitable for washing, packaging, cleaning, production of semi-finished products (there is experience in the production of potato flakes and starch). The flesh of the tubers does not darken when raw or cooked.
Features of agricultural technology
The variety is highly resistant to most viral and fungal diseases, but you should pay attention to the average resistance to late blight in the tops (despite this, the resistance to late blight in the tubers is high).
The variety is very responsive to watering, does not tolerate drought.
It is also important to take into account that potatoes of this variety need more space for crop formation: the recommended planting density of certified seeds (production of marketable potatoes): 40-42 thousand plants / ha.
Nitrogen is very important for the GALA variety: on average, 200 kg for ae, taking into account the characteristics of the soil. On light soils, nitrogen must be added fractionally: during planting and during vegetation (when the plants reach a height of 10-15 cm).
In the budding phase and the beginning of flowering, it is necessary to carry out nitrogen foliar feeding in order to prevent physiological aging of the tops and prolong the work of the foliar apparatus. Top dressing during the growing season can be carried out together with fungicidal treatments at the rate of 5-10 kg of nitrogen according to ae.
Differs in low sensitivity to metribuzin, can be used on seedlings.
After desiccation, the variety quickly forms a firm skin. Stores well (without loss of turgor) until spring.
BALTIK ROUZ
In Russia, it is included in the State Register in 2019.
Medium early variety for table use. High-yielding, number of tubers per bush: 12-15 pieces. The marketability of tubers is high.
It has an attractive appearance: the color of the peel is bright red, the shape of the tubers is aligned, the eyes are small. For its quality characteristics, the people received the name "red GALA".
Has excellent taste. Recommended for washing and packaging.
Features of agricultural technology
It is characterized by high resistance to Y virus, leaf roll virus.
Plastic to weather conditions, permissible cultivation in rainfed agriculture. For the formation of a good harvest of marketable potatoes, the recommended planting density: 45-47 thousand plants / ha.
Fertilizers: when grown for commercial purposes, the recommended rate of nitrogen application is 140 kg per d.v. It is better to introduce in two steps: 2/3 of the norm when planting and 1/3 - until the plant reaches a height of 15 cm. It is not recommended to overfeed with nitrogen, so as not to prolong the growing season.
When watering, it is necessary to control its uniformity.
It is moderately sensitive to metribuzin, can be used before germination, after entry - only in a dosage of no more than 0,3 l / ha.
The yield growth is uniform. Harvesting should be scheduled no earlier than three weeks after haulm removal.
Desiccation is also better done fractionally: after the first treatment, do the second after 5-7 days and monitor the secondary growth of tops.
Suitable for long-term storage.
