Взаимодействие факторов «генотип – среда» затрудняет отбор селекционного материала. Для уменьшения его влияния исследователи разработали различные способы классификации сред. Ранее было предложено использовать коэффициенты корреляции между урожайностью одних и тех же сортов, выращенных в ряде сред, для классификации этих сред.</p><p>Цель работы заключалась в классификации лет на основе корреляции урожайности специально подобранного набора сортов яровой мягкой пшеницы и проверке применимости данной группировки для селекционного материала в питомниках.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Материалом исследования являлись сорта, линии и селекционные образцы коллекционного питомника, конкурсного испытания и гибридных популяций соответственно. Исследование проведено с 2010 по 2017 г. В качестве основы для классификации лет использован корреляционный анализ урожайности 19 маркерных сортов различного эколого-географического происхождения. Полученные коэффициенты корреляции для урожайности маркерных сортов и урожайности селекционных образцов в питомниках для тех же пар лет сравнивали с помощью U-критерия Манна – Уитни.</p></sec><sec><title>Результаты</title><p>Результаты. Рассматриваемые годы классифицированы на три группы: 1) 2010, 2013 г.; 2) 2011, 2012 и 2014 г.; 3) 2015, 2016 и 2017 г. Коэффициенты корреляции урожайности маркерных сортов и урожайности образцов из остальных питомников для рассматриваемых лет достоверно не различались. Следовательно, типизация лет на основе реакций маркерных сортов может быть справедливо применена к остальному селекционному материалу.</p></sec><sec><title>Заключение</title><p>Заключение. Предлагается формировать и использовать набор маркерных сортов в экологическом испытании для получения дополнительной информации о целевых средах и более надежного принятия решений о браковке селекционного материала. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Genotype–environment interaction complicates selection of lines in plant breeding. Researchers have developed different ways to classify environments to mitigate its effect. The use of correlation analysis between yields of cultivars grown in different environments was earlier proposed for classification of these environments.</p><p>The aim of this research was to classify years on the basis of correlations of the yields in a specially selected set of spring bread wheat cultivars and to verify the application of such classification to breeding material in different nurseries.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The material for the experiment included cultivars, lines and breeding samples from the collection nursery, competitive variety trials, and the nursery for segregating populations, respectively. The experiments were conducted from 2010 through 2017. The correlation analysis between the yields of 19 marker cultivars of different ecogeographic origin was used as the basis for the classification of years. The calculated correlation parameters for the yields of marker cultivars and those of the breeding material in nurseries for the same pairs of years were compared using the Mann–Whitney U-test.</p></sec><sec><title>Results</title><p>Results. The years under consideration were classified into three groups: 1) 2010 and 2013; 2) 2011, 2012 and 2014; 3) 2015, 2016 and 2017. Correlations between the yields of the marker cultivars showed no significant differences from those of the genotypes from other nurseries across the analyzed years. Consequently, the classification of years based on the reactions of marker cultivars can be justifiably extended onto other breeding material.</p></sec><sec><title>Conclusion</title><p>Conclusion. It is suggested to select and use a set of marker cultivars in multi-environment trials to obtain additional information about target environments and make more informed decisions on culling plant breeding materials. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>экологическое испытание</kwd><kwd>корреляционный анализ</kwd><kwd>селекция растений</kwd></kwd-group><kwd-group xml:lang="en"><kwd>multi-environment trial</kwd><kwd>correlation analysis</kwd><kwd>plant breeding</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Алтайского научно-исследовательского института сельского хозяйства № 0790-2014-0007 «Создание принципиально новых стрессоустойчивых сортов и гибридов зерновых, зернобобовых, масличных, просовидных и сорговых культур, обладающих высокой и стабильной урожайностью, повышенным качеством зерна и продуктов его переработки, на основе комплексного изучения генофонда, использования инфекционных и провокационных фонов оценки селекционного материала».
