Results of ecological testing variety numbers of fiber-flax cultivars for yield and adaptability in the conditions of the non-chernozem zone of the Russian Federation

Abstract

The article presents the results of an ecological test of selection numbers of fiber-flax (Linum usitatissimum L.), bred in the conditions of the North-Western region, on the yield of flax fiber and the parameters of adaptability in the conditions of the Central Non-chernozem region. We tested 3 variety numbers: LS-1, LS-2 and LS-3. As a standard, we used a highly productive Impulse variety zoned in the region, of domestic selection, which was entered in the State Register of Breeding Achievements in 2003. According to the results of the studies, high adaptability in combination with potential productivity was obtained in the number of fiber-flax LS – 3 (1,14). Under variable meteorological conditions, the LS – 2 variety number and the Impulse variety had high resistance to stress (- 0.21 - 0.02, respectively). The most productive in contrast conditions was LS-3 (1.84 t / ha). The numbers LS – 1 (2.20) and LS – 3 (1.60) were the most responsive to the improvement of cultivation conditions.
