| Abstract | Goal. To determine the development of septoriosis of different varieties of soft winter wheat. Methods. Field, measurement, calculation and comparison, analysis, statistical. The results. The development of septoriosis on soft winter wheat varied depending on the variety and phase of growth and development. Thus, in the tillering phase, on average over two years of research, this indicator fluctuated within the range of 4.0–4.7%, which changed similarly over the years of research. In 2012, there was no development of septoriosis on soft winter wheat crops. The highest damage by septoriosis was noted during the emergence phase of soft winter wheat plants in the tube. Thus, on average over the three years of research, this indicator was 4.8 % in Knyaginya Olga, 5.2 in Zolotokola, 11.5 and 13.5 in Podolyanka and Favoritka, respectively, and 21 in Myronivska 808 and Bilotserkivska semi-dwarf varieties. 9 and 21.4 %. A similar trend was observed over the years of research. Thus, in 2010, the intensity of the lesion ranged from 5.4 to 22.4 %, from 4.8 to 21.5 % in 2011, and from 4.3 to 23.1 % in 2012. In the phase of milk ripeness of the grain of soft winter wheat varieties, the intensity of damage by septoriosis decreased to 1.3–5.5 %. A similar trend was observed over the years of research. Conclusions. The intensity of damage to soft winter wheat plants by septoriosis varies depending on the growth phase and variety. Thus, in the tillering phase, the intensity of the lesion is 3.9–4.7 %. However, in the phase of emergence into the tube, the intensity of plant damage increases to 4.8–21.9 %, earing – 3.8–20.3 %, depending on the variety. In the phase of milky grain ripeness, this indicator decreases to 1.3–5.5 %. On average, over three years of research, the grain yield of the Zolotokolos varieties was 10.7 t/ha, Myronivska 808 – 9.2, and Favoritka – 8.5 t/ha, which is significantly higher than the control (Podolyanka variety) by 0.9–3.1 t/ha. The Knyagina Olha variety had the lowest grain yield and amounted to 3.6 t/ha, and the Bilotserkivska semi-dwarf variety had 6.7 t/ha, which is significantly less compared to the control (LSD05=0.41–0.49). | ||
