During the study of the promoter region of the TaSAP-Al gene on the allelic composition of Sap5, Sap39 and Sap2606 loci, it was shown that winter wheat varieties and lines from the collection used in the selection process in the Republic of Belarus in 2014 refer to 4 haplotypes and most of the tested samples (45.6 %) belongs to the haplotype II. It was found that the haplotype IV contributes to an increase in thousand-kernel weight and yield by 5.2 and 9.2 %, and haplotype I – an increase in spike length and total number of spikelets per spike by 4.4 and 2.2 % compared with the average values of these indicators. It was also found that the presence of deletion at position –1810 bp has a positive effect on spike length, total number of spikelets per spike and yield, the presence of insertion at position –1637 bp – spike length, and the presence of deletion in this position – on yield. The positive effect of SNP-2606C at position –2606 bp on thousand-kernel weight, spike length and yield was shown.
