Abstract

Goal. To evaluate collection flax accessions of the Institute of Bast Crops for resistance to Fusarium wilt and anthracnose in the North-east Ukraine, to identify, on the basis of screening, varieties with medium and high resistance to pathogens and to create new initial breeding material on artificial infections.

Materials and methods. The study was carried out in the infectious-provocative nursery in the field of the Institute of Bast Crops in compliance with the "Methodical guidelines for the phytopathological evaluation of resistance of breeding material of fiber flax to Fusarium wilt" and " Methodological instructions on the phytopathological evaluation of resistance of fiber flax to diseases" in 2011 ­ 2016.

Results and discussion. In 2011-2016, 115 accessions of the Ukrainian national flax collection from 15 countries were evaluated for resistance to Fusarium wilt and anthracnose in the infectious nursery: 31 accessions from Ukraine; 26 – from Belarus; 15 - from France; 8 - from Russia; 8 - from Poland; 6 - from the USA; 4 - from Lithuania; 4 - from the Czech Republic; 4 – from Argentina; 3 - from the Netherlands; 1 accession from Belgium; 1 - from Germany; 1 - from Kenya; 1 - from Morocco; 1 from Canada; and 1 accession of unknown origin. Varieties were assessed for resistance to disease in comparison with reference varieties. There were 8 Fusarium-resistant and 3 Colletotrichum-resistant accessions. Most of the varieties under investigation were medium resistant to Fusarium wilt (59.1%) and susceptible to anthracnose (82.6 %).

Conclusions. As a result of the research into resistance of the collection material to Fusarium wilt and anthracnose in the infectious nursery, sources of resistance to diseases were identified: ACM Duff (UF0402149) from Canada, Atena (UF0401927) from Poland, LKS 2 (UF0402112), LKS 10 (UF0402101), LKS 11 (UF0402102), LKS 12 (UF0402196), LKS 14 (UF0402194), LKS 15 (UF0402198) from Ukraine - to Fusarium wilt; LKS 1 (UF0402111), LKS 11 (UF0402102) from Ukraine, Fort (UF0401942) from the Republic of Belarus - to anthracnose. Ukrainian fiber flax accessions combining resistance to two diseases: LKS 11 (resistance to Fusarium wilt and anthracnose), LKS 2, LKS 10, LKS 12, LKS 14, and LKS 15 (resistance to Fusarium wilt and medium resistance to anthracnose), LKS 1 (medium resistance to Fusarim wilt and resistance to anthracnose) were singled out.
