At the present stage of agroindustrial complex development of Ukraine to get in the required range of natural foods is growing need for plant raw material increased that will help to diversify the range of food and defense mechanisms of the human body and longevity increase.

In recent years in Ukraine Chicory Root crop area was decreased to 600 hectares due to the absence of the concerned owner and industry processing, and the products consumed by the population was imported from abroad, as market evidenced. 

Chicory Root (Cichorium intubus L.) – is a valuable food and industrial crop that has healing properties. Along with the cultivation of other highly technical agricultural crops chicory is economically viable culture, raw material of which is used in food, pharmaceutical industry and other industries. Products of its processing are part of a range of food products, including dietary nutrition.

Root chicory is contain 16-24% inulin, which promotes toxins and radionuclides release, 2–5 % of fruit sugars, 1.2 % – protein, 0.6% – fats, acrolein, furfural, valeric acid, intybin essential oil – tsykoriol, vitamins A, B1, B2, B12, PP and more than 30 mineral elements.  

Inulin that contained in chicory is primarily positively influence on gastrointestinal activity, bifid bacteria activity promotes, growth of Salmonella bacteria inhibits and cholesterol content levels optimizes. Therefore, it is used in pharmacology for the manufacture more than 40 medications that are used in the treatment of the stomach, liver, kidneys, heart, nervous system diseases.

Chicory Root is biennial plant. In the first year of life root forms for industry, and also a valuable nutritious and healing food for farm animals. In 100 kg of roots is contained 25.7 kg of feed units, while fodder beet are containing them just 14.5 kg. The land mass is well eaten by animals in the fresh and silage form. In the second year chicory is form a stem that blooms and fruits form.

The results of the researches are indicate that Umanskyy 95, Umanskyy 96, Umanskyy 97, Umanskyy 99 varieties are different from control (Umanskyy 90) by the greater mass of root, and hence and yield.

During the research years the root mass per plant, on average, ranged from 287–405 g.

It should be noted that for research years the root mass of Umansky 90 variety in 2011 was 386 g, which is on 23.6% more than in 2010 and 25.6% higher than in 2012. In Umanskyy 95 variety the highest index was in 2011, which was 371 g, which is on 9.4% more than in 2010 and 15.9% higher than in 2012.

The high index of Umanskyy 96 variety was recorded in 2011 – 364 g, which is on 1.9% more than in 2010 and 19.8% higher than in 2012.

In an average years of research the root mass in Chicory Root on the control (Umanskyy 90) was 323 g, in Umanskyy 95 – 340 g, which is on 5.3% more, Umanskyy 96 – 338 g, which is on 4.6% higher, in Umanskyy 97 – 358 g, which is on 10.8% more, in Umanskyy 99 – 379 g, which is on 17.3% more compared to the control.

Thus, Chicory Root varieties of selection of Uman experimental breeding station IBCISB Umanskyy 95, Umanskyy 96, Umanskyy 97, Umanskyy 99 on average over three research years, compared with control (Umanskyy 90) are root mass greater on 4.6-17.3% formed.

The yield increase of Chicory Roots varieties of Uman experimental breeding station IBKITSB selection of Umanskyy 95, Umanskyy 96, Umanskyy 97, Umanskyy 99 on average by research years in comparison with control (Umanskyy 90) was 8–22 % on the variety depending.

The yield of Umanskyy 95 variety with index of 36.3 t/ha in 2011 was higher than in 2010 on 6.7% and on 20.6% compared with 2012. Productivity, which provided by Umanskyy 96 variety in 2011, with the index of 38.3 t/ha is enabled somewhat exceed the yield in 2010 and significantly exceed this index in 2012.

However, by the stable yields in research years is Umanskyy 99 variety characterized. The highest index was in 2011 – 39.7 t/ha, that on 6% more than in 2010 and on 18.1% more than in 2012.

Key words: variety, root crop, chicory root, root mass.
