  The root vegetables have a pivotal role in the vegetable consumption and to form a healthy diet. The consumption of natural juices, like apple-beetroot are becoming more popular and the drying-, the pharmaceutical- and canning industry require more beetroot to process. For the processing, the industry requires easily peeled and round shaped roots, therefore to use the proper variety is very important. The primary quality parameters are the inner color intensity, uniform color and water soluble dry matter content.
  4 beetroot varieties were evaluated (Libero, Rubin, Detroit 2 and Cylindra) in the 3 years experiment which was carried out at the University of Debrecen, Institutes for Agricultural Research and Educational Farm, Botanical and Exhibiton Garden. The soil type was calcareous chernozem. Leaf length, shape index and water soluble solid content were measured, and sensory evaluation was carried out on taste, inner color intensity and white ring.
  To summarize, we can state the exception of Rubin genotype all of the varieties are suitable for second cultivation and good for processing (canned, juice, powder).

  The importance of beetroot lies in the numerous health benefits, attributed to its wide-ranging array of minerals, vitamins and bioactive compounds which play a key role in the human diet. Generally, beetroot is consumed for its root, however, its leaves also contain a good amount of bioactive compounds. The experiment was carried out with four beetroot varieties in order to compare the amount of bioactive compounds in the root and the leaf. The analyzed data were total dry matter content, total polyphenol, flavonoid and vitamin C.

  Results have shown that roots contain the highest amount of bioactive compounds. Nevertheless, leaves can be also considered a significant source. Therefore, consumption of the young leaves is highly recommended due to their availability after thinning or at maturity stage (60 days after the germination). Of the examined varieties, ‘Libero’ demonstrated the highest total polyphenol, flavonoid and vitamin C values, although it was found to be statistically insignificant.
