Abstract. A wide variety of Hemerocallis hybrida hort. cultivars of the genus Hemerocallis L. – red daylily, daylily (family Hemerocallidaceae R. Br.) occupies a leading place among flower-ornamental plants when used in open ground in Russia and abroad. In the forest-steppe zone of Western Siberia, long-term variety testing of daylilies is carried out, which are valuable as an ornamental crop. Transformation of genotypic traits in daylilies is possible by using selection methods and selecting hybrids adapted to local cultivation conditions. There is no information on selection work in Siberia. The originality of this study lies in the production of hybrid seedlings by not only interbreeding, but also free self-pollination of H. hybrida varieties in the forest-steppe zone of the Novosibirsk region, as well as in identifying and evaluating their practical qualities, which represents the novelty and relevance of this work. The purpose of the study is to investigate the breeding potential of H. hybrida varieties cultivated in the forest-steppe zone of Western Siberia and to select promising hybrids. Methods. Hybridological analysis is based on the use of the method of intervarietal hybridization and selection of first-generation hybrids. Results. Based on the obtained biometric data, the specificity of inheritance of morphological traits for flower color and shape, abundance, duration and timing of flowering was established. The growth and development of daylily seedlings, their morphobiological significance in long-term (2014–2024) cultivation in the Siberian region were analyzed. Productive parental varieties with positive fertilizing ability were identified. Metrological environmental factors influencing the seed productivity of hybrids were substantiated. The possibility of obtaining hybrids with new genotypes was established. Scientific novelty of the study is that for the first time in the conditions of the foreststeppe zone of the Novosibirsk region, 30 varieties of H. hybrida were crossed and hybrids were selected from intervarietal and free pollination. The patterns of inheritance of morphological features were revealed, 18 hybrid seedlings were selected and described, resistant and promising in terms of economic and biological qualities to the conditions of the forest-steppe zone of Western Siberia.
