【 摘 要 】

In the conditions of the Western Forest-Steppe of Ukraine the most common and harmful disease of flax is anthracnose, the development of which reached 79 %. During 2018-2019, the development of anthracnose on flax varieties and hybrids was monitored in breeding nurseries of the Institute of Agriculture in the Carpathian Region (Ukraine). The meteorological conditions of the growing season favoured the attack of all varieties of flax by anthracnose in the budding phase. The spread of the disease intensified by the onset of early yellow ripeness. The results of two-year studies of flax damage by anthracnose are presented, the development of which in the budding phase were in 2018 − 5.0-15.0%, in 2019 − 3.0-18.0%; in the phase of the onset of early yellow ripeness, respectively 27.0-79.0 and 24.0-75.0%. According to the research results, the least diseased varietal samples were revealed and recommended as parental forms in the breeding process for resistance to anthracnose.
