In a comparison between 21 varieties, root weight ranged from 981.3 g/msuperscript 2 (WG3B) to 577.8 g/msuperscript 2 (Ludion). The ratio of root : aboveground parts was from 3.5 (Alta) to 8.7 (WG3B). A positive correlation was found between root mass and DM production of the aboveground parts harvested on the last sampling date, except in the group of varieties with the most rapid root growth. S, P, Mg and K concentrations in the root were 62, 32, 83 and 6% of that in the assimilatory tissues, whereas Ca and Na concentrations were 3.4 and 1.75 times higher, respectively. Cu, Mn and Zn concentrations in the roots were 290, 340 and 390% of those in the shoots.
