   <abstract xml:lang="ru">
    <p>Цель исследования – изучить сопряженные морфологические и фотобиологические особенности сортообразцов овсяницы красной (Festuca rubra L.) в коллекционном питомнике и выявить источники селекционных признаков для создания новых сортов. Исследования проводили в 2023–2024 гг. на базе Федерального научного центра кормопроизводства и агроэкологии им. В.Р. Вильямса. Почва дерново-подзолистая, гумус – 2,1–2,3 %; рН KCl – 5,3; Р2О5 и К2О (по Кирсанову) – 152,0 и 93,0 мг/кг соответственно. Питомник заложен без повторностей с размещением стандартов – сортов Искринка и ВИК 16 через каждые 5 селекционных номеров. Изучали 37 сортообразцов различного эколого-географического происхождения. Стандарты – сорта Искринка (газонного) и ВИК 16 (кормового использования). Зависимость параметров газообмена от концентрации углекислого газа (СО2) и фотосинтетически активной радиации (ФАР) изучали с использованием портативного газоанализатора LI COR 6800 при интенсивности ФАР от 0 до 1500 µМ/(м2•с). В результате кластеризации по основным морфо-биологическим признакам сортообразцы распределились на 2 кластера: кластер I (26 сортообразцов) – c узкими и короткими листьями, низкорослые, с урожайностью зеленой массы 1,19 кг/м2, урожайностью семян 57,5 г/м2; интенсивностью фотосинтеза 5,71 µM СО2/(м2•с), транспирации – 7,77 мМ Н2О/(м2•с); лучшие номера (3/6, 3/36, 3/37), наряду с сортами Искринка, Гостенка и Везелка, могут использоваться в качестве источников селекционных признаков при создании сортов газонного направления; кластер II (11 сортообразцов) – высокорослые, с крупными широкими листьями; высокой урожайностью фитомассы – 1,99 кг/м2, семян – 71,7 г/м2; интенсивностью фотосинтеза 13,18 µM СО2/(м2•с), транспирации – 14,14 mМ Н2О/(м2•с); сортообразцы 3/4, 3/13, 3/29 и сорт ВИК 16 могут использоваться в качестве источников селекционных признаков при создании сортов кормового направления. Фактор «генотип сортообразца» достоверно влияет на проявление основных результирующих признаков с силой 7,5–35,8 %, фактор освещенности – 22,4–52,6 %.</p>

    <p>The aim of the study is to investigate the associated morphological and photobiological features of red fescue (Festuca rubra L.) accessions in a collection nursery and to identify the sources of breeding traits for creating new varieties. The studies were conducted in 2023–2024 at the V.R. Williams Federal Scientific Center for Forage Production and Agroecology. The soil was sod-podzolic, humus – 2,1–2,3 %; pH KCl – 5,3; P2O5 and K2O (according to Kirsanov) – 152.0 and 93.0 mg/kg, respectively. The nursery was established without replicates with the placement of standards – Iskrinka and VIK 16 varieties – every 5 breeding numbers. A total of 37 variety accessions of different ecological and geographical origin were studied. The standards were Iskrinka (lawn) and VIK 16 (forage) varieties. The dependence of gas exchange parameters on the concentration of carbon dioxide (CO2) and photosynthetically active radiation (PAR) was studied using a portable gas analyzer LI COR 6800 at PAR intensity from 0 to 1500 µM/(m2•s). As a result of clustering by the main morpho-biological characteristics, the variety accessions were divided into 2 clusters: cluster I (26 variety accessions) – with narrow and short leaves, low-growing, with a green mass yield of 1.19 kg/m2, seed yield of 57.5 g/m2; photosynthesis intensity of 5.71 µM CO2/( m2•s), transpiretion – 7.77 mM H2O/(m2•s); the best numbers (3/6, 3/36, 3/37), along with the Iskrinka, Gostenka and Vezelka varieties, can be used as sources of selection traits in the creation of lawn varieties; cluster II (11 variety accessions) – tall, with large wide leaves; high phytomass yield – 1.99 kg/m2, seeds – 71.7 g/m2; photosynthetic intensity of 13.18 µM CO2/(m2•s), transpiration – 14.14 mM CO2/(m2•s); variety accessions 3/4, 3/13, 3/29 and variety VIK 16 can be used as sources of selection traits in the creation of forage varieties. The “variety accession genotype” factor reliably influences the manifestation of the main resulting traits with a strength of 7.5–35.8 %, the illumination factor – 22.4–52.6 %.</p>
