Sugar beet breeding is very complex because it involves numerous sugar beet root traits that must be measured and investigated, as a basis to create hybrids with high yield, high sugar content and appropriate root shape. In this paper were investigated combining abilities and mode of inheritance for root weight, root diameter and dry matter content of different sugar beet genotypes. Combining abilities were assessed by line x tester method. The mode of inheritance was assessed by evaluation of hybrids versus parents mean. For the estimation of combining abilities and mode of inheritance of analyzed traits were used 8 monogerm pollinators, 3 monogerm cms lines and their 24 F1 hybrids. The mode of inheritance for root weight and root diameter for most hybrid combinations was dominance of better parent. For inheritance of dry matter content intermediate level and partial domination of one parent were obtained.
