Abstract

The aim of the research was to develop a cultivar of naked oat with improved traits of productivity and grain quality for cultivation under climate change conditions and utilization in breeding practice as a source of useful economic properties. The pre-flag leaf’s area was found to render a considerable effect on the formation of the number of grains and grain weight in the panicle and on the total biomass (r= 0.78-0.85), while the area of leaves depended on the duration of the period from seedling emergence to wax ripeness (r = ‒0.79) and on agroclimatic conditions during the growing season (HTC, r = 0.76).  The flag leaf’s pigments (Chl a, Chl b, Car) were observed to have a sizable effect on the weight of 1000 grains during the period from flowering to milk ripeness (r = 0.79-0.88). The new naked cultivar ‘Virovets’ (1h07) with improved levels of productivity and grain quality (1000 grain weight: 29.2 g; crude protein content: up to 19.8%; oil of the oleic-linoleic group: 7.71%, grain volume weight: 670 g/l; pubescence: weak) was developed to be cultivated for food and feed purposes and be used in naked oat breeding as a source of high grain quality.
