A monogenic dominant control of resistance to Ustilago nigra and Ustilago hordei has been determined. The recombination rate ranged from 5.1 to 9.5%. It was concluded that there is an incomplete linkage of these genes. A method of natural infection on the intensive background under the field conditions and testing (artificial) evaluation of the genotypes has been introduced. A number of varieties have been developed: Akademichnyi, Aivenho (2012), Burevii (2013), Snihova koroleva (2014), Deviatyi val (2015), Prezent (in the State Trials from 2015).
