The analysis of meteorological conditions in the autumn vegetation period of winter wheat indicates a climate warming and increasing aridity. Climatic aridification in the Republic of North Ossetia-Alania is manifested by an autumnal lack of moisture in the soil and an increase in average daily air temperatures in the period corresponding to the recommended sowing dates for winter wheat. Soils based on pebbles and gravel have a leaching type of water regime, which additionally causes a lack of moisture.
The main purpose of the study is to identify promising collection samples of soft winter wheat with high productivity and adaptability indicators to use them for further breeding of varieties that suit the local soil and climate conditions. According to the results of the analysis, the soft winter wheat varieties with high overall adaptability, stress resistance and high productivity include: No T1 (var. graecum), Metsamori 16 (var. erytroleucum), No T3 (var. ferrugineum) and Naz (var. barbarossa). These samples can become sources of valuable economic traits and can be used in the breeding process.
Keywords: winter wheat varieties, climate aridification, breeding indices.
