BYELORUSSIAN AND BELGIAN FIBER FLAX VARIETIES IN WESTERN SIBERIA

Results are given from field experiments conducted in 2012-2013 to study fiber flax varieties, bred in Belarus and Belgium, in the experimental field of the Siberian Research Institute of Agriculture and Peat, located in the subtaiga zone, and to develop promising adapted hybrid material. The cultivars Velich, Iva and Yarok, bred in Belarus, and Pamyati Krepkova, bred in Tomsk, significantly exceeded the standard Tomskiy 16 in the total height and the technical stem length (by 2-5 cm). The Belgian cultivars were on a level with the standard and somewhat below. The Dutch cultivars Safi, Suzanne, Hermes, Agatha, Bonita, Melina and the Byelorussian cultivar Yarok significantly, by 2-5 percent, exceeded the standard in the fiber content in the stems. The Byelorussian cultivars Vasilek, Velich and Grot were below the standard by 2-4 percent for this character. The cultivars Levit-1, Iva, Yarok, bred in Belarus, and the Belgian cultivars Suzanne, Bonita, Electra and Hermes were above the standard by 25-50 percent in fiber yields. Major Byelorussian and Belgian cultivars had the ratio between length and diameter of flax fiber, being an indirect index in fiber quality assessment, below the standard. The Belgian cultivars Agatha and Hermes and the Byelorussian cultivar Grot were on a level with the standard and somewhat below as to this character. The most productive and adapted cultivars have been included in the breeding process as donors of productivity and fiber quality.
