Genetic productivity potential in soft spring wheat varieties of the collection of the All-Russian Institute of Genetic Plant Resources (VIR) in the Trans-Urals

Abstract

Abstract Out of 277 varieties, according to the complex of economically valuable characteristics, 72 were distinguished in 2017-2020, 2022, of which 20 varieties were intensive. Their average yield in the dry years of 2017 and 2020 is 305-354 g/m2 (st. 260-283 g/m2), while the best of the collection were: Grenada, AC Pollet, Jin Mai 71, Greina, Toronit (380-442-502 g/m2). High potential yields are characterized by: Alabuga, Grenada, Kommissar, India 288, Remus (550-592-633 g/m2). In dry years, the environment index Ii is negative (-77; -48), in other years it is positive (10; 7) and quite pronounced in 2022 (106). Plasticity (lower ranks and their sums) is expressed in Grenada, Kommissar, Alabuga, Greina, AC Pollet. Positive effects on the reaction of the medium - Er, are well manifested in: India 288, Margarita, SSL 46-50, Grenada, Omskaya 41, Kedem, Tyumenskaya 25, Tyumenskaya 29; negative - in 3-4 media in Line (k-65021), UI Alta Blanca, Omskaya 36, Toronit, India 288, Jin Mai 71, reduce their value. The following varieties are distinguished with the complex of yield indices (5 pcs.): Grenada, AC Pollet, Omskaya 41, Greina, Toronit, Uralosibirskaya 2. The selected varieties are recommended for breeding for productivity.
