| description | The article presents the results of screening of 20 varieties of fiber flax (Linum usitatissimum L.) according to the yield of flax fiber and adaptability parameters in the conditions of the Northwestern region. The variety Dobrynya (Russia) zoned in the region was taken as standard. On average, over the years of research (2015-2017), the yield of flax fiber in varie-ty numbers varied in the range of 1.22-2.67 t/ha. According to the calculations of the environmental conditions index, the most favorable conditions for growth and development of fiber flax varieties were in 2016-2017 (Ij = +0.07-0.73), the worst in 2015 (Ij = -0.79). The highest yield of fiber (t/ha) was observed in varieties Y 51269 (2.67) (China), A-236 (2.66), Dobrynya (2.49), M-249 (2.48) and L 280-02 (2.38) (Russia), Glazur (2.48) (Ukraine), which exceeded the average among the varieties by 9.7-2.3 %. Among them, the varieties Y 51269 (China) and A-236 (Russia) exceeded the standard by 0.17-0.18 t/ha, in two years of three the growth was reliable. The studied varieties did not fully realize their relatively high yield potential and were characterized by a strong degree of variability. The best indicators of stress resistance (0.79-1.16) were observed in Vesnichka, L-2 (Russia), B-226 (Lithuania), Tyy (China) the varieties and lines Dobrynya, M-249, A-236, L-6, L-4, L-5, L 280-02 (Russia), Glazur, Vruchiy (2.34-2.32) (Ukraine) and Tyy (2.33) (China) were genetically flexible genotypes (2.56-2.23). Samples B-226 (Lithuania), Glazur (Ukraina), L-2-1, Vesnichka, and L 280-02 (Russia) had high homeostatic values and low coefficient of variation. Highly responsive to environmental conditions were samples L-5, L-3, L-4, A-236, M-249, Dobrynya, (Russia), Sxy20, Sxy, Y 51269 (China), Vruchiy (Ukraine); plastic ˗- varieties Glazur (Ukraine), L 280-02, L-5-1, 85-58-26-20 (Russia); weakly responsive − Lu-1, Tyy (China), L-2-1, L-205, Vesnichka (Russia), B-226 (Lithuania). According to the yield of flax fiber and the complex of adaptability parameters, the cultivars B-226 (Lithuania), Y 51269 , Tyy, Lu 1 (China), L 280-02, L-6, A-236, Dobrynya (Russia), Vruchiy and Glazur (Ukraine) were distinguished. They had high stress resistance, genetic flexibility, plasticity and stability. They can be used as sources of adaptability when creating new varieties of fiber flax. |
