The plasticity and stability of spring oats in yield and the mass of and 1000 grains

The results of the researches of 2017-2019 conducted at Uyarsky State Variety Trials Site located in a forest-steppe zone of Krasnoyarsk Region were presented in the study. The research purpose was the identification of the most plastic varieties, and also the varieties with the greatest stability, spring oats on the productivity of grain and mass of 1000 grains at their cultivation using intensive technology. The tasks were to calculate ecological plasticity and stability of varieties of spring oats on the productivity and mass of 1000 grains. The research methods were the experiments and observations made according to the technique of the state variety trial. The experiments were made in quadruple frequency, the registration area of an allotment being 25 sq.m. The varieties of filmy and hull-less oats acted as the objects of the research: Tubinsky, Argument, Golets, Sayan, Sig and Ural-2. The variety Tubinsky was taken as the standard. The indicators of ecological plasticity and stability were determined with the help of S...
