At the present time by far not all of the experimental breeding institutions evaluate original collection specimens of winter and spring wheat for their resistance to loose smut Ustilago. For this reason, quite often vulnerable strains are used in crosses. This leads to subsequent rejection of a large amount of seeds and strains of hybrids because of their susceptibility to this disease. Breeding wheat for resistance to loose smut can be improved considerably if in selecting the initial parental pairs for crosses the resistant strains are used. For this reason, of great importance is rating of the wheat specimens of different strains and species which are used extensively by the experimental breeding network USSR in creating new productive strains.
