Improvement of the technology for the cultivation of winter wheat in the arid zone of the Stavropol Territory based on the optimization and renewal of the varietal base of winter wheat grown using the No-Till technology. The work was carried out in 2019–2020 in the arid zone of the Stavropol Territory. In the experiment to study the assessment of varieties of winter wheat grown according to the predecessors of peas and sunflower, we studied 15 varieties. The economic variant, variety Yuka, was used as a control one. The total size of the experimental plot is 1.9 hectares. The yield of the predecessor peas was 23.92-39.44 q/ha, depending on the variety. The highest-yielding variety turned out to be Tanya (39.44 q/ha), which is 12.6% higher than the economic variant Yuka (35.04 q/ha). An increase of 4.8-7.1% in relation to the economic variant Yuka was given by the varieties Aksinya and Volny Don. All studied varieties showed a fairly high degree of resistance to the development of pathogens. The highest prevalence rate and intensity of development of pyrenophorosis in winter wheat plants sown after peas was noted in the Alekseich variety – 67% prevalence and 0.63% intensity, and the lowest in the Aist variety – 22% and 0.33%, respectively. The highest prevalence and development rate of pyrenophorosis in winter wheat plants sown after sunflower was observed in the Krasa Dona variety – 47% prevalence and 0.63% intensity, and the lowest in the Niva Stavropolya variety – 21% and 0.33%, respectively.
