Abstract

The article presents the results of research on the detection and identification of morphological and cultural characteristics of the pathogens causing root rot in winter wheat under the conditions of Almaty Region. The research was conducted in 2021 in the laboratory facilities of the «Research and Production Center for Microbiology and Virology» using commonly accepted methods in microbiology and phytopathology. The statistical analysis was conducted using the R Studio software through the Student's t-test for analysis of variance. The critical level of significance was determined using the p-value. During the study, it was determined that winter wheat exhibited signs of fusarium and root rot through analysis of roll cultures on filter paper and determination of seed infection on seeds germinated on sand. It was found that the main pathogens causing root rot were two species of fungi, Bipolaris sorokiniana and Fusarium spp. The results of the phytosanitary analysis for disease incidence varied on average from 91% to 94% affected seeds. Seed infection was detected in the Almala variety, with a prevalence of 46% for Bipolaris sorokiniana and 45% for Fusarium spp. For the Canada variety, the prevalence rates correspond to 56% for Bipolaris sorokiniana and 38% for Fusarium spp. The growth dynamics of the P15 and P15I strains of Bipolaris sorokiniana on nutrient media isolated from wheat seeds indicate that the environment and the isolate factor influence the colony area. The growth dynamics of Fusarium F2 and F3 colonies were shown to be significantly correlated with the area of the substrate at p < 0.05 level. The biological characteristics of Fusarium spp and Bipolaris sorokiniana conidia, including the length, width, and quantity of the segments, were determined.
