Dolphin potato variety
Dolphin is a Belarusian table potato variety (Solanum tuberosum) of early ripening. Bred by the staff of the RUE "Scientific and Practical Center of the National Academy of Sciences of Belarus for Potato and Fruit and Vegetable Growing". In 2002 he was included in the state register of breeding achievements of the Russian Federation in two regions: Central (Bryansk, Vladimir, Ivanovsk, Kaluga, Moscow, Ryazan, Smolensk, Tula regions) and Central black earth (Belgorod, Voronezh, Kursk, Lipetsk, Oryol, Tambov regions ). Differs in early amicable ripening, the formation of a large number of tubers, drought resistance, high productivity.
It should be said right away that there is another variety with a similar name - "Dolphin". This is a completely different potato and has nothing to do with our hero.
The time from the appearance of full shoots to ripening is 60-75 days, the first digging can be carried out already on the 45th day of the growing season.
Plant of medium height, intermediate type. Stems are semi-erect. Leaves are medium in size, dark green in color. The leaf is large. The waviness of the edge of the sheet plate is very weak or absent at all. Corolla is medium in size and white in color.
The Dolphin's root system is well developed, 14-16 medium-sized tubers are formed in one nest, with a mass of 80-132 grams each, there are very few trifles. The tubers are aligned, have an oval-rounded shape. The peel is yellow, smooth to the touch. The pulp is light yellow in color. The eyes are small, inconspicuous, shallow.
According to the results of state tests, the marketable yield of potatoes is 170-256 c / ha, at the level of indicators of the Bryansk early variety and by 62 c / ha more than the standards Zhukovsky early... During the first digging, on the 45th day of the growing season, 82−195 c / ha were collected, which is comparable to the Izor standards and 26 c / ha more than the results of Zhukovsky early. During the second digging, on the 55th day after full germination, 132−215 c / ha were obtained, which is at the level of Izor's indicators and 43 c / ha higher than the Zhukovsky early standards. The maximum yield was recorded in the Tula region - 295 c / ha were harvested there, 159 c / ha more than Pushkinets results. According to the originator, the potential yield indicator can reach up to 540 c / ha! The marketability of tubers is 88-96%, at the level of established standards. Keeping quality is excellent - 90-99%.
Dolphin has good taste. It is classified as culinary type A, the tubers are very weakly boiled, making them ideal for preparing salads and frozen vegetable mixtures. In general, the variety will show itself perfectly in absolutely any dish, except, perhaps, mashed potatoes. The pulp contains 11.2-15.1% starch, 0.4-1.7 lower than Zhukovsky and Bryansk early standards.
The variety is very picky about soil fertility. It will grow best on light sandy loam and loam rich in nutrients and minerals. Plants are resistant to drought, but they are very sensitive to waterlogging of the soil, especially in the initial stages of growth. Be careful with watering, an abundant amount of moisture in the soil will have a very bad effect on the development and health of the potato.
Tubers have a pronounced dormancy period of more than 90 days. In this regard, before planting, it is recommended to germinate them for better germination and earlier yield. The originator advises the following planting density: when cultivating in order to obtain marketable products, 45-48 thousand plants per hectare of area should be planted, and when grown on seed - 52-55 thousand tubers per hectare. A discharged landing is recommended according to the scheme 70 × 32−35 cm. The dolphin is responsive to the introduction of an increased amount of mineral fertilizers into the soil.
The variety is resistant to the causative agent of potato cancer, wrinkled and banded mosaic, leaf-rolling virus, golden cyst nematode. According to the All-Russian Research Institute of Phytopathology, it is susceptible to late blight in tubers and moderately susceptible to tops, however, it manages to yield the crop before it appears. Medium resistant to common scab.
Our hero is very much appreciated by gardeners for the high yield, provided by a large number of tubers in the nest, as well as for early amicable ripening. The excellent keeping quality of tubers also deserves attention - they can be stored for more than a year without losing their consumer and marketable qualities and without germinating.
The disadvantages include increased demands on soil fertility, as well as sensitivity to waterlogging of the soil. In especially rainy seasons, yields can be significantly reduced. The gardeners noticed that with a fairly large number of tubers in the nest, the percentage of non-marketable ones is very high. Potatoes tend to acquire bizarre shapes, but not in all cases - perhaps in this situation the "age" of the seed material matters, although the Dolphin is not prone to rapid degeneration. Also, the disadvantages include very long stolons, which makes the nest non-compact and complicates the process of digging potatoes - there is a high probability of damaging tubers located far from the "center" of the bush.
