Abstract
The allelic composition of the dwarfing genes Rht1, Rht2 and Rht8 was studied in 75 winter wheat varieties and lines which may be of interest for the selection process of wheat in Belarus. The effect of allelic forms of these genes on the plants height was confirmed, and their influence on thousand-kernel weight, spike length, number of spikelets per spike, grain mass per spike, grain mass per plant, number of grains per spike, and general and productive bushiness was assessed. The sources of the Rht-B1b, Rht-D1b and Rht8c alleles, which lead to a decrease in the plant height and can be used in the selection process of wheat, have been identified.
