Conclusions. By using WRT carriers in F 1 hybrids, different levels of dominance of the trait main spike length: from overdomination (heterosis) to depression were detected. Overdomination, partial positive dominance and higher level of heterosis have been established in most combinations when crossing the winter wheat varieties Kolumbiia, Ekspromt carrying the 1AL.1RS translocation.
