The role of “Collection of the phytopathogenic microorganisms - agents of flax diseases” in flax breeding on group resistance to diseases

One of the stages in researches on resistance of a breeding and collection material of flax varieties to pathogens is formation, maintenance and practical usage of created in VNIIL “Collection of microorganisms - agents of flax diseases”. Using collection biosamples at creation of the artificial inoculated plots there were revealed the forms of fibre and oil flax resistant to a fusarium wilt and rust at level about 85100 %, to anthracnose and pasmo - at level about 6075 %, and to three diseases: a fusarium wilt, rust, anthracnose or pasmo. Varieties of fibre flax with group resistance to fusarium wilt, rust (85-100 %), and with middle resistance to anthracnose or pasmo (51-55 %) are developed.
