Abstract
Root chicory (Cichorium intybus var. sativum Lam.) is a valuable industrial crop, a raw material for the food industry.
The product from root-crops is produced in its pure form and is an important component in the production of tea and coffee drinks, bakery and confectionery products.
Its value for industry is determined by the content of inulin, fructose, intibin and chicoreol in taproot.
Inulin, obtained from chicory roots, is widely used as a prebiotic in the dairy and pharmaceutical industries.
The VIR collection includes 44 accessions of root chicory of various ecological and geographical origin.
The purpose of our work was to study the variability of the accumulation of sugars, including inulin, in root chicory under different sites of cultivation.
The material of the study was 8 accessions of root chicory from the VIR collection.
The plants were grown in 2021-2022 in the open field of the Pushkin Laboratories of VIR (St.
Petersburg) and the Rostov Vegetable experimental station on root chicory (Yaroslavl region). Determination of sugar content (monosaccharides, disaccharides and inulin) was carried out according to the Bertrand method.
As a result, it was found that the content of dry weight in taproots on average in sites of cultivation varied from 21.2 to 26.9% (CV=5.6%). The total sugar content was in the range of 32.8-64.9% DW (CV=14.2%), of which: monosaccharides 0.9-15.2% DW, disaccharides 0.1-31.7% DW and inulin 22.3-51.6% DW. In Pushkin, the content of total sugars varied within 41.0-58.8% DW, of which monosaccharides 0.9-5.4% DW, disaccharides 0.1-19.2% DW, inulin 31.0-47.0% DW. In the Rostov station, total sugars varied within 55.0-64.4% DW, of which monosaccharides 7.3-13.8% DW, disaccharides 0.5-22.9% DW, inulin 22.7-50.8% DW. It was found that the site of cultivation affects the accumulation of monosaccharides and total sugars, and the accumulation of inulin depends on the genotype and site of cultivation.
We selected accessions of root chicory with a high content of inulin, which can be used as starting material in breeding.
It was revealed that the Petrovsky cultivar is characterized by a stable accumulation of inulin in two sites of cultivation and can be used for industrial cultivation.
