Agrobiological evaluation of new spring oat varieties (Avena sativa L.) developed at the national center of grain named after P.P. Lukyanenko

Currently, the problem of developing spring oat varieties with high adaptability potential, capable to produce highquality yields under unstable growing conditions, is of great relevance. The purpose of the current study was to analyze the economically valuable traits of new spring oat varieties ‘Kiyura’ and ‘Debutny’ developed at the National Center of Grain named after P.P. Lukyanenko (Krasnodar Region, Krasnodar, Russia) in comparison with with the standard variety ‘Valdin 765’. The study has demonstrated that the new oat varieties surpass the standard variety in productivity. On average, over four years of study (2016–2019) at the NCG named after P.P. Lukyanenko the variety ‘Kiyura’ exceeded ‘Valdin 765’ by 5.6 t/ha. The maximum productivity of the variety ‘Kiyura’ with 8.03 t/ha was recorded in the year of 2017 with favorable weather conditions. Over three years of trials (2018–2020), the variety ‘Debutny’ yielded on 6 t/ha more than the variety ‘Valdin 765’. The maximum productivity of the variety ‘Debutny’ in 2018, which was characterized by favorable weather conditions, was 5.9 t/ha. As part of the development and preservation of a national catalog of particularly valuable plant genetic resource samples, there have been formed herbariums of the varieties ‘Kiyura’ and ‘Debutny’, designated as nomenclature standards. The herbarium samples were registered in the VIR Herbarium database and sent for storage to the Herbarium of Cultivated Plants of the World, Their Wild Relatives and Weeds (WIR), the National Center for Plant Genetic Resources.
