spp.) относится к семейству Polygonaceae, распространен по всему миру и используется как овощная культура и лекарственное растение, поэтому его культивирование стало предметом многочисленных исследований. В двух отдельных экспериментах были выращены 44 образца из Института генетики растений и исследований сельскохозяйственных культур (IPK, Германия) и 10 генотипов, собранных в разных районах Ирана. Эксперименты проводились в тепличных условиях по полностью рандомизированной схеме в трех повторениях, в ходе которых оценивались семь признаков: длина листа, длина листовой пластинки, площадь листовой пластинки, количество жилок, диаметр черешка, количество листьев и сухая масса листа. Оценка взаимодействия генотипа и признака (GTI) методом биплот-анализа объяснила 77 и 78 % наблюдаемой изменчивости в первом и втором экспериментах соответственно. В ходе испытаний были выявлены два типа расположения генотипов: нонагональное в первом и гептагональное во втором испытании, при этом генотипы 16 и 23 показали высокие средние значения сухой массы листьев в первом и втором испытаниях соответственно. Генотипы 44 и 50 были определены как идеальные, имеющие решающее значение для программы генетического улучшения щавеля, особенно с точки зрения урожайности листьев. Что касается дискриминационной способности, а также типичного потенциала, площадь листовой пластинки и диаметр черешка позволили выявить различия между генотипами как идеальными признаками в обоих испытаниях. Между сухой массой листьев и площадью листовой пластинки в обоих экспериментах наблюдалась умеренная положительная корреляция (r = 0.57 для первого эксперимента, r = 0.49 для второго эксперимента). Таким образом, площадь листовой пластинки можно считать информативным признаком для построения индекса отбора с целью повышения урожайности листьев, наряду с сухой массой. Результаты показывают, что площадь листовой пластинки и диаметр черешка являются ключевыми признаками для отбора высокоурожайных генотипов щавеля, а биплот-метод оценки GTI предоставляет практичный визуальный подход для выявления лучших генотипов, способствуя эффективному отбору в селекции. Подобная стратегия может быть рекомендована в будущих исследованиях для описания прогностических и тщательных методов отбора, которые помогут определить идеальные признаки для селекции щавеля и других овощных культур.</p></abstract><trans-abstract xml:lang="en"><p>Sorrel (Rumex spp.) belongs to Polygonaceae. It is distributed worldwide and used as vegetable crop and medicinal plant, so considerable research has been dedicated to its cultivation. Forty-four accessions from the Institut für Pflanzengenetik und Kulturpflanzenforschung (IPK), Germany, and ten genotypes collected from some areas of Iran were grown in two separate trials. The trials followed a completely randomized scheme with three replicates in a greenhouse environment. Seven traits were assessed: leaf length, blade length, lamina area, number of veins, petiole diameter, number of leaves, and dry leaf weight. The genotype × trait interaction (GTI) biplot model accounted for 77 and 78 % of the observed variability in the first and second trials, respectively. A nonagon and a heptagon were identified in trials, respectively, while genotypes 16 and 23 showed high mean values of dry leaf weight in the first and second trials, respectively. Genotypes 44 and 50 were identified as perfect genotypes, highly promising for sorrel genetic improvement programs, especially with regard to leaf yield. As for discriminative capacity, as well as typical potential, lamina area and petiole diameter best demonstrated differences among genotypes as perfect traits in both trials. There was a moderate positive correlation between dry leaf weight and lamina area across both trials (r = 0.57 for the first trial and r = 0.49 for the second trial). Therefore, lamina area can be considered an informative trait for constructing a selection index to improve leaf yield, along with dry leaf weight. The results demonstrate that lamina area and petiole diameter are key traits for selecting high-yielding sorrel genotypes, and the GTI biplot provides a practical visual approach to identify superior genotypes, facilitating efficient selection in breeding. Such a strategy can be recommended for future studies to describe prognostic and meticulous selection methods in order to recognize best traits for the breeding of sorrel and other vegetable crops.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сухая масса листьев</kwd><kwd>дискриминационная способность</kwd><kwd>идеальный генотип</kwd><kwd>типичный потенциал</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dry leaf weight</kwd><kwd>discriminative capacity</kwd><kwd>perfect genotype</kwd><kwd>typical potential</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bourang M.K., Hassandokht M., Nazeri V., Rasoulnia A., Moghanloo G.D.
