Resistance of Perspective Spring Durum Wheat Samples to Foliar Diseases

Abstract: Листостебельные болезни (ржавчина и пятнистости) вредоносны для яровой твердой пшеницы во всех зонах ее выращивания. Целью исследований являлась иммунологическая оценка 25 перспективных сортов и линий яровой твердой пшеницы к листостебельным болезням в фазе проростков и взрослых растений и идентификация у них генов устойчивости. Изучаемый материал получен из Казахстанско-Сибирской сети улучшения яровой пшеницы (КАСИБ) в 2019 г. Оценку устойчивости к бурой, стеблевой и желтой ржавчинам проводили на инфекционном… Show more

“…Sufficiently effective selection for resistance is confirmed by the low frequency of occurrence of the dominant allele of the susceptibility gene to P. tritici-repentis -Tsn1. Among the 43 studied cultivars, it was identified only in two -Soyana and Gordeiforme 08-25-2 (Rsaliyev et al, 2020).…”

“…In the system of the Kazakh-Siberian program (KASIB), the following samples of durum wheat were identified (highly resistant to leaf spot pathogens in the field): 1693d-71, 2021d-1, Gordeiforme 1591-21 (Samara Research Institute of Agriculture), D-2165 (Research Institute of Agriculture of the South-East), Gordeiforme 08-107-5, Gordeiforme 178-05-02, Gordeiforme 05-42-12 (Omsk Agricultural Research Centre) (Gultyaeva et al, 2020;Rsaliyev et al, 2020). A significant part of durum wheat cultivars included in the state register of Russia according to the description of the authors and the results of the study in the state variety network show resistance (R), medium resistance (MR) or medium susceptibility (MS) to these pathogens.…”
