Features of Yielding Capacity Development of Barley Cultivars of Siberian Selection

Abstract

The assessment of the zoned cultivars of double-row and six-row barley in terms of influence of productivity traits on final yield in a competitive variety trials for 2009-2022 (except 2011 and 2019) was carried out. Researches were conducted under the conditions of the open Krasnoyarsk forest-steppe. As objects of the research double-row barley varieties were used: Buyan, Kedr, Biom, Olenek, Acha, Bakhus, Krasnoyarsky 80, as well as six-row barley varieties: Agul 2 and Sobolek. The regression analysis showed that the yield substantially depended on a number of grains in an ear and a 1000-grain mass for double-row varieties as well as for six-row ones of the siberian ecotype. The difference of varieties of the krasnoyarsk early days selection – Krasnoyarsky 80 and Bakhus is revealed. Little influence of all basic productivity traits on yield is typical for them.
