The objects of the study were plants of 14 varieties of durum wheat Triticum durum Desf. Cultivation was carried out in a climatic chamber at a temperature of 18 ± 1°C under the conditions of a sixteen-hour photoperiod. To study the growth characteristics of the root system of seedlings, the length of the main root and the length of the adventitious roots of the upper and lower tiers were measured; thus, the growth rate of the root system was determined.
