Abstract
The results of research on spring triticale varieties for 2015-–2019 showed that root rot severity on Uzor variety by the end of the growing season (st. 85) ranged from 4,0 to 30,4 %, Doublet – from 9,2 to 42,3 % and Sadko – from 4,6 to 32,3 %. A high severity of root rot was noted in years when the amount of precipitation in the growing season of spring triticale was the lowest (2015) or the highest (2017) relative to the norm. A polynomial dependence (R2 = 0,75) was found between the area under the disease progress curve and the amount of precipitation for the period from sowing to soft dough (st. 85), indicating that root rot severity of spring triticale increases under conditions of both insufficient, and excess moisture.
