Сравнительная оценка исходных диплоидных сортов ржи и их тетраплоидных аналогов в Западной Сибири Н.Н. Ермошкинa2025 • 11 • 2 • 90-96 Селекция растений / Plant breeding The results of a comparative assessment of the initial diploid rye varieties and their tetraploid analogues in Western Siberia N.N. Ermoshkina Abstract: Currently, it is of particular interest to establish the effect of doubling the number of chromosomes on breeding-significant traits in the breeding process. In 2018–2021, field and laboratory studies were conducted to compare the economically valuable characteristics and properties of the original diploid rye varieties and their tetraploid analogues in Western Siberia. The material for the study was two pairs of analogues: diploid varieties Korotkostebelnaya 69 and Chulpan and their tetraploid forms Tetra Korotkaya and Vlada. As a result of the comparative analysis, during the transition from the diploid to the tetraploid level, there is a similarity of characteristics in height and winter hardiness of plants, since the inheritance of these characteristics is polygenic, which favorably affects the resistance of plants to stress. In tetraploid analogues, there is a significant increase in yield by 17.2–23.5 % and grain size Результаты сравнительной оценки исходных диплоидных сортов ржи и их тетраплоидных аналогов в Западной Сибири

В настоящее время особый интерес представляет установление влияния удвоения числа хромосом на селекционно значимые признаки в процессе селекции. В 2018–2021 гг. проведены полевые и лабораторные исследования с целью сравнительной оценки по хозяйственно ценным признакам и свойствам исходных диплоидны...
