Для селекции растений, продуцирующих крахмал с оптимальными для переработки свойствами, необходимы эффективные методы оценки физико-химических параметров большого количества образцов крахмала. Соответственно, данные по изменчивости тех или иных фенотипических признаков имеют важное значение как для развития фундаментальных работ по идентификации локусов генома, отвечающих за широкий спектр характеристик крахмала картофеля, так и для прикладных работ по ускоренной селекции новых сортов технического назначения. Оценка размеров крахмальных гранул при помощи микроскопии – один из самых доступных и потому распространенных методов фенотипирования. Нами разработан состоящий из четырех этапов подход к оценке геометрических параметров гранул крахмала: первый этап – выделение крахмала из клубня, второй – получение микрофотографий образцов крахмала, третий – обработка и анализ полученных изображений в свободно распространяемой программе ImageJ, четвертый – построение графиков распределения гранул крахмала по геометрическим параметрам. Показано, что гранулы крахмала различных сортов и гибридов картофеля различаются по морфологии и могут быть дифференцированы методом микроскопии с получением данных о диаметре Фере и округлости частиц. Так, моды диаметра Фере гранул крахмала сортов Алена, Невский и гибрида 785/8-5 составляют 5, 22 и 67 микрон соответственно. В распределении гранул крахмалов этих сортов и гибрида по округлости наблюдаются лишь незначительные отличия. Микрофотографирование гранул крахмала с последующей обработкой изображений представляет собой доступный, экономичный, простой и эффективный подход к фенотипированию сортов и гибридов картофеля Solanum tuberosum L. по физико-химическим параметрам крахмала. Этот метод может применяться для ускоренного анализа большого числа образцов на ограниченном количестве природного материала, в том числе в полевых и хозяйственных лабораториях.</p><sec><title> </title><p> </p></sec><sec><title> </title><p> </p></sec></abstract><trans-abstract xml:lang="en"><p>Potato starch is a valuable and aﬀordable technical raw material for a number of industries. For selection of plants producing starch with optimal processing properties eﬀective methods for physicochemical parameters evaluation of a large number of starch samples are needed. Thus, variability of phenotypic traits data are important both for fundamental works on identiﬁcation of genomic loci responsible for a wide range of potato starch characteristics as well as for applied accelerated selection of new varieties for technical use. Estimating the morphology of starch granules by microscopy is one of the most accessible and therefore widespread methods of phenotyping. We developed a four-step approach to the estimation of the geometric parameters of starch granules. It includes an isolation of starch from the tuber (stage 1), the preparation of mi-crographs of starch samples (stage 2), processing and analysis of the images obtained in the freely distributed ImageJ program (stage 3), and the construction of distribution curve for starch granules by geometric parameters (stage 4). It was shown that the starch granules of diﬀerent varieties and hybrids of potato diﬀer in morphology and can be diﬀerentiated by microscopy with obtaining data on the Feret’s diameter and the circularity of the particles. Thus, typical values of the Feret’s diameter of starch granules of “Alena” and “Nevsky” varieties and 785/8-5 hybrid are 5, 22 and 67 microns, respectively. The distributions on circularity of starch granules of these varieties and the hybrid have only minor diﬀerences. Light optical microscopy of starch granules followed by digital image analysis is an aﬀordable, economical, simple and eﬀective approach to phenotyping the varieties and hybrids of potato Solanum tuberosum L. on the physicochemical parameters of starch. The approach may be applied for accelerated analysis of a large number of samples on a limited amount of natural material in the ﬁeld and countryside economic laboratories.</p><p> </p></trans-abstract><kwd-group xml:lang="ru"><kwd>крахмал</kwd><kwd>морфология</kwd><kwd>микроскопирование</kwd><kwd>диаметр Фере</kwd><kwd>округлость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>starch</kwd><kwd>morphology</kwd><kwd>microscopy</kwd><kwd>Feret’s diameter</kwd><kwd>circularity</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">Blennow A., Hansen M., Schulz A., Jurgensen K., Donald A.M., Sanderson J.
