    <p>Аннотация. Из различных абиотических стрессов при производстве риса наиболее важным во многих странах является засуха или водный дефицит. Цель исследования – изучить коллекционные, гибридные и селекционные сорта и образцы риса на толерантность к длительной почвенной и воздушной засухе, отобрать засухоустойчивые формы для выведения новых сортов. Методы. Объекты исследований – 68 сортов и образцов суходольного риса, которые возделывали на орошаемом и затопляемом участках (г. Пролетарск, Ростовская обл.) в трехкратной повторности. Площадь делянки – 10 м2, норма высева – 500 семян/м2. Полив проводили пуском воды из оросительного канала после посева 10 мая слоем 10 см и в период роста при полном высыхании поверхности почвы. Степень засухоустойчивости определяли по соотношению величины признака в опыте к таковой на контроле (О/К). Научная новизна. Определена различная степень засухоустойчивости образцов риса по соотношению продуктивности зерна в условиях водного дефицита и достаточного обеспечения водой, выявлены новые закономерности. Результаты. Установлено, что сорта и образцы при засухе и затоплении формировали различную урожайность зерна, которая при дефиците влаги составила в среднем 63,7 % от нормы. Корреляция урожайности при засухе с урожайностью при затоплении была слабой положительной (r = 0,23 ± 0,01), с их соотношением О/К – средней положительной (r = 0,59 ± 0,01), а связь урожайности при затоплении с засухоустойчивостью – средней отрицательной (r = –0,64 ± 0,01). Выявлены 10 сортов и образцов со степенью засухоустойчивости более 75 %, такие как Ан-Юн-Хо, Чан-Чунь-Ман, Золотые всходы, Маловодотребовательный, ЗУЛК 2, ЗУЛК 6, у которых соотношение урожайности при засушливых и нормальных условиях, составляло от 77,9 до 91,6%. Максимальную урожайность в условиях засухи сформировал новый сорт селекции АНЦ «Донской» Аргамак (6,10 т/га) и селекционные образцы 7970 (Командор × Чан-Чунь-Ман) – 5,24 т/га, ЗУЛК 8 – 4,90 т/га.</p>

    <p>Abstract. Of the various abiotic stresses, the most important limitation of rice production in many countries is drought or water scarcity. The aim of the study is to study collection, hybrid and breeding varieties and samples of rice for tolerance to prolonged soil and air drought, to select drought-resistant forms for breeding new varieties. Methods. The objects of research – 68 varieties and samples of dry land rice were cultivated in irrigated and flooded areas (Proletarsk, Rostov region) in three repetitions. Plot area – 10 m2, seeding rate – 500 seeds/m2. Irrigation was carried out by the release of water from the irrigation canal after sowing on May 10 with a layer of 10 cm and during the growth period with complete drying of the soil surface. The degree of drought resistance was determined by the ratio of the value of the trait in the test to that in the control (T/C). Scientific novelty. The different degrees of drought resistance of rice samples were determined by the ratio of grain productivity under conditions of water deficit and sufficient water supply, new regularities were revealed. Results. It was found that varieties and samples during drought and flooding formed different grain yields, which, with a moisture deficit, averaged 63.7 % of the norm. The correlation between the yield during drought and the yield upon flooding was weak positive (r = 0.23 ± 0.01), with their T/C ratio – average positive (r = 0.59 ± 0.01), and the relationship between the yield upon flooding and drought resistance – medium negative (r = –0.64 ± 0.01). 10 cultivars and samples with a degree of drought tolerance of more than 75 % were identified, such as An-Yun-Ho, Chan-Chun’-Man, Zolotye vskhody, Malovodorebovatelnyy, ZULK 2, ZULK 6, in which the ratio of yield under dry and normal conditions ranged from 77, 9 to 91.6 %. The maximum yield in drought conditions was formed by a new selection variety of the ARC “Donskoy” Argamak – 6.10 t/ha and selection samples: 7970 (Komandor × Chan-Chun’-Man) – 5.24 t/ha, ZULK 8 – 4.90 t/ha.</p>
