The influence of wheat-rye translocation 1BL/1RS and allelic combinations of 7+9/j and 7+8/j on the genetic degradation of wheat dihaploid lines was studied. The results of the study showed close to normal genetic degradation, which is assessed on the basis of the presence or absence of 1BL/1RS translocation in the DH lines obtained from eight hybrid combinations. Due to the association between the allele encoding the Glu-B1 high-molecular fraction 7+9 and the low-molecular allele ‘j’ from the locus Glu-B3, dihaploid lines were obtained with certain combinations of high-(HMW) and low-(LMW) molecular weight glutenin configurations. This phenomenon could significantly limit the possibilities of combinational selection in some cases.
