Актуальные Направления Селекции На Улучшение Питательной Ценности Клубней Картофеля

Abstract: Цель работы: изучение эффективности использования доноров и родительских линий при реализации важнейших направлений селекции на основе оптимальных вариантов гибридизации и отбора селекционно ценных генотипов для улучшения питательной ценности клубней новых перспективных сортов картофеля. Материал исследований: сортообразцы из коллекции ВИР и ВНИИКХ, созданные на основе межвидовой гибридизации и последующих возвратных скрещиваний с сортами S. tuberosum. Исследования проводили в 20082018 годах на экспериментальн… Show more

“…The THz-TDS method allows to clearly establish the presence or absence of the pathogen in the plant, as well as assess the degree and depth of damage to plant tissues. If the variety “Nadezhda” [ 47 ] with the skin is considered the most affected, and the variety “Meteor” without the skin is the least, then based on the data obtained and the characteristics of varieties 46 , we can assume the following dependence of the THz spectra of parameters on the degree of late blight. As the phytopathogen spreads: ε’ and n first decrease (early stages), then increase; ε’’ and α first increase, then decrease ( Table 1 ).…”
