SEARCHING FOR RESISTANCE SOURCES TO WHEAT COMMON BUNT (Tilletia caries (DC.)

Аннотация

Common bunt (Tilletia caries (DC.) the disease occurs in areas where autumn wheat is grown. In our
country, most of the zoned wheat varieties are infected with this disease. Therefore, foreign germoplasm should look
for sources of strength. In our research in the field of artificial epizootic environment, the Hungarian 21 varieties of
soft wheat Tilletia caries (DC.) of the pathogen was made the phytopathological and genetic-selection analysis. The
study revealed that 15 wheat varieties are resistant to diseases, of which 8 wheat varieties were highly resistant to
diseases (IT-0). They are; Ati, Békés, Berény, Csillag, Futár, Pilis, Szala and Rege. We say 7 varieties that are
resistant to common bunt (IT-1), they are Kalász, Mentor, Göncöl, Fény, Garaboly, Szemes and Vitorlás. The
indicator of the biomass index (NDVI) was determined at the stages of vegetative development of plants in ears,
flowering phase and milky stage. The average value of the biomass index is higher than 0.70, with a high score of
9 varieties that have Ati, Mentor, Hajnal, Göncöl, Tisza, Csillag, Futár, Garaboly and Szala. As a result of the
analysis of structural characteristics, the varieties Körös, Mentor, Tisza, Szala, Szemes and Rege showed a high
index for all characteristics. As a result, disease-resistant and high-performance varieties can be presented as
common bunt resistant specimens in immune selection.
