Optimization of the height of plants of spring durum wheat is an indispensable attribute of breeding programs in all regions of its cultivation. The aim of the research was to analyze methods of selection based on the characteristic and study of varieties and selection lines with different plant height reduction genes in contrasting climatic environments. Field experiments involving medium-sized and low-growing genotypes were carried out at the ecological points of the Middle Volga region (Bezenchuk), Western Siberia (Barnaul), the Urals (Kurgan, Orenburg), Kazakhstan (Aktyubinsk), the Lower Volga (Volgograd), Central Chernozem and the North Caucasus (Orel, Krasnodar) and in environmental points of KASIB. As a result of the conducted studies, carriers of the genes for reducing the height of plants of durum wheat were proposed for use in the selection for the optimization of the plant heights: RhtAnh - for the steppe regions (Bezenchukskaya zolotistaya, Bezenchukskaya 210, 1368D - 18), RhtB1b - for the Black Earth and the North Caucasus (1591D-21 )
