Создание высококачественных семян льна масличного с использованием новых методов отбора растений является важным направлением совершенствования первичного семеноводства культуры. Существующие методы создания таких семян по-прежнему остаются сложными и трудоемкими. В связи с этим разработка более совершенных методов получения обновленных семян с высоким уровнем проявления посевных, сортовых качеств и морфофизиологических свойств является актуальным и имеет практическое значение.</p></sec><sec><title>Методы</title><p>Методы. Эксперименты выполняли в соответствии с методиками закладки, проведения полевых опытов со льном, методическими рекомендациями по семеноводству льна масличного. Оценку посевного качества, семенного материала проводили в соответствии с действующим ГОСТ, сортового качества — методом грунтового контроля.</p></sec><sec><title>Результаты</title><p>Результаты. Выявлена высокая эффективность создания обновленных семян льна масличного с использованием метода отбора растений в периоде вегетации — от начала до окончания полного цветения, позволившего обеспечить достоверное увеличение их выхода до 61,5%, по сравнению с контролем. Отбор растений в интервале от начала до окончания полного цветения обеспечил сохранение посевных качеств, созданных семян на уровне контроля — отбора по действующей методике, повышение однородности показателей морфофизиологических свойств семян, в том числе однородности проростков семян по длине на 4,6%. Метод отбора с удалением нетипичных по морфологическим признакам растений по сравнению с контролем позволил увеличить выход обновленных семян льна масличного на 29,7%, улучшить их морфофизиологические свойства. Сортовое качество обновленного семенного материала при всех методах его создания характеризовалось отсутствием нетипичных по цвету семян, незначительными различиями между вариантами по выравненности сортовых признаков.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. The creation of high-quality oilseed flax seeds using new plant breeding methods is an imperative principle with the advent of better crop seed production. Current methods for creating such seeds continue to be complicated and laborious. In this regard, the development of more advanced methods for obtaining renewed seeds with a high level of manifestation of sowing, various types and morphophysiological properties is relevant and has practical importance.</p></sec><sec><title>Methods</title><p>Methods. The experiments were carried out in accordance with the methods of planting, conducting field experiments with flax, and methodological recommendations for seed production of oil flax. The assessment of sowing quality and seed material was carried out in accordance with the current certification system , varietal quality — by the soil control method.</p></sec><sec><title>Results</title><p>Results. The high efficiency of creating updated oilseed flax seeds using the method of plant selection during the growing season — from the beginning to the end of full flowering, which allowed for a significant increase in their yield to 61.5%, compared with the control. Selection of plants in the interval from the beginning to the end of full flowering ensured the preservation of the sowing qualities of the created seeds at the control level — selection according to the current method, as well as increasing the uniformity of indicators of the morphophysiological properties of seeds, including the uniformity of seed sprouts along the length by 4.6%. The selection method with the removal of plants atypical in morphological charakteristics compared with the control allowed to increase the yield of updated oilseed flax seeds by 29.7%, improve their morphophysiological properties. The varietal quality of the updated seed material for all methods of its creation was characterized by the absence of atypical seeds in color and minor differences between the options in the uniformity of varietal characteristics.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>лен</kwd><kwd>семена</kwd><kwd>семеноводство</kwd><kwd>метод отбора</kwd><kwd>растения</kwd><kwd>качество</kwd></kwd-group><kwd-group xml:lang="en"><kwd>flax</kwd><kwd>seeds</kwd><kwd>seed production</kwd><kwd>selection method</kwd><kwd>plants</kwd><kwd>quality</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследования выполнены в рамках государственного задания Министерства науки и высшего образования в Федеральном научном центре лубяных культур по теме FGSS-2019-0016.</funding-statement><funding-statement xml:lang="en">The research was carried out within the framework of the State assignment of the Ministry of Science and Higher Education at the Federal Scientific Center for Bast Crops on the topic FGSS-2019-0016.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Кривошлыков К.М., Трунова М.В., Лукомец А.В.
