The new facultative barley variety ‘Vivat’ adapted to the conditions of the North Caucasus

Abstract

Barley has a prominent role in the grain balance, because it is a valuable crop with many various uses. Barley ranks second in its sown area, both in Russia and in the Rostov region. Previously, spring barley was used as an insurance crop for “restoring” the frozen crops of winter barley. Currently, for this purpose, facultative barley varieties are used, capable of giving yields both when sown in au­tumn and in spring. The aim of the research was to create a facultative barley variety, combining high productivity, quality and resistance to extreme environmental factors. As a result of long-term breeding work, a new variety of facultative barley ‘Vivat’ has been developed. In the creation of the variety, the most winter tolerant varieties were used, such as ‘Tayna’ (Ukraine), ‘Radical’ (Krasnodar, RF), ‘Paoli’ (the USA). The varieties with high potential productivity are ‘Master’ (Zernograd, Russian Federation) and ‘Khutorok’ (Krasnodar, Rus­sian Federation). During the years of competitive testing (2011-2017), the variety ‘Vivat’ showed advantages over the standard variety ‘Master’ and the best zoned variety ‘Timofey’ according to such important traits as high productivity, winter tolerance, resistance to lodging and drought. In the North Caucasus (6) region, the variety ‘Vivat’ also showed high productivity, winter tolerance, resistance to lodging, drought, and diseases. Since 2018 the variety has been introduced into the State List of Protected Breeding Achievements.
