Genetic sources of naked oat for selection in the climate of Central Siberia

Abstract

The study of the genetic characteristics of plant response to changes in environmental conditions makes it possible to use the achievements of selection in more effective ways. In 2019-2020 in the conditions of the open forest-steppe of Krasnoyarsk region naked samples of spring oat have been studied to identify the parent material. Sources for important selection characteristics have been highlighted: early maturity of Gosha (k-15120, Belarus), which matured seven days earlier than the standard and the American sample MF9521-19 (k-15226, USA) which matured six days earlier than the standard; two early ripening samples of Gosha (k-15120, Belarus) and MF9521-19 (k-15226, USA) were assigned to the lodging resistant cultivar (8.5 points according to a 9-point system); the most coarse-grained cultivar with a mass of 1000 grains over 30 g are the following: the mass of MF9521-19 (k-15226, USA) is 38.4 g; the mass of Vladyka (k-15408, Belarus) is 37.7 g; the mass of Zhytomyr (k-15502, Ukraine) is 36.8 g; the mass of Local China (k-15149, China) is 34.0 g; the mass of Visit (k-15501, Ukraine) is 30.2 g; the mass of Progress (k-15339, Omsk region) is 29.7 g; the mass of Gosha (k-15120, Belarus) is 29.6 g.
