During the creation of new wheat cultivars (Triticum aestivum L.), in addition to high yield potential and good technological quality, it is necessary to incorporate genes responsible for resistance to lodging, low temperatures and adaptability to different production conditions. NS Lenija, a new winter wheat cultivar developed at the Institute of Field and Vegetable Crops (National Institute of the Republic of Serbia) was created by crossing the three divergent parents: cultivar Kupava (Russia) and the cultivars Donna (Serbia) and Aria (Serbia). By crossing these parents, genes responsible for high yield potential, good technological quality, adaptability and stability were successfully combined, enabling this cultivar to be successfully cultivated in the agroecological conditions of Southeast Europe. During the two-year trials of the Commission for the registration of varieties, NS Lenija successfully passed the DUS test (distinctness, uniformity and stability), and on the 7 tested locations achieved a significantly higher average grain yield compared to the grain yield of the check cultivars. When evaluating its chemical and technological properties, it was classified in quality class II, farinograph quality group A-2, and in the technological group of improvers.
