| description | The current paper has presented the estimation results of the adaptive indicators of the traits “productivity” and “a falling number” of nine winter rye varieties developed in theFederalAgriculturalResearchCenterof the North-East named after N. V. Rudnitsky. The study was conducted in 2015-2019 inthe experimental plots of the Falenskaya breeding station, the branch of the FSBSI of FARC of the North-East (theKirovregion). The weather conditions in the years of study greatly varied. There has been established that throughout the years of study, the most promising variety was “Batist” (5.15 t/ha). High values of genetic flexibility were identified in the varieties “Batist” (5.21 t/ha), “Sara” (5.05 t/ha), “Nioba” (5.06 t/ha), “Rushnik” (4.96 t/ha). According to the parameters of ecological adaptability and stability of the trait “productivity”, there have been identified such varieties of the intensive type as “Grafinya” (bi = 1.22; S2d = 0.01), “Rushnik” (bi = 1.39; S2d = 0.04) and such varieties of extensive type as “Flora” (bi = 0.63; S2d = 0.09), “Falenskaya 4” (bi = 0.75; S2di = 0.03) and “Batist” (bi = 0.76; S2di = 0.05). High stress resistance was demonstrated by the varieties “Flora” (–1.98 t/ha), “Batist” (–2.01 t/ha). Under contrasting weather conditions, in the periods of grain filling and ripening, there has been identified the most adaptive variety “Rushnik” (according to the trait “falling number”), which had the highest average indicator 195 c throughout the years of study (with a minimum value of 109 c in unfavorable weather conditions of the year and a maximum value of 275 c in favorable weather conditions of the year |
