Assessment of the adaptive potential and ecological plasticity of a new variety of spring barley Fermerskiy for Northwest Russia

In Northwest Russia, creation and introduction of new varieties cereals characterized by early maturity, high adaptive potential ecological plasticity is one the most important tasks. A generation barley needed that combines yields with feed qualities grain, resistance to lodging grain shedding. We carried out field laboratory studies a variety spring Fermerskiy in an experimental Leningrad Research Institute Agriculture "Belogorka". 2021, Fermersky was transferred for state testing. The midseason growing season 72–87 days. Over three years competitive testing (2018–2020), yield increase 1.25 t/ha relative Suzdalets standard (3.12 t/ha). highest 5.27 obtained 2019, under conditions low moisture supply. average index (Jsp) 1.48 (min 1.11, max 1.94). (ds/dk) 7.91 6.92, 9.08), consistently formed plasticity, diseases lodging.
