The new spring barley variety ‘Granik’

Abstract

The purpose of the current study was to evaluate the high-protein spring barley variety (Hordeum vulgare L.) ‘Granik’ in the conditions of the left bank of the Saratov region. The study was carried out on the basis of the Krasnokutsk breeding experimental station, located in the Saratov region, Krasnokutsk district, the village of Semennoy on chestnut soils (coordinates of the experimental plot is 50.914007, 47.068303). The years of 2013, 2014 and 2020 (from 8 years of studying the new variety in the competitive variety testing (CVT)) were average humid; the years of 2016 and 2017 were wet; the years of 2015, 2018 and 2019 were acutely arid. There was established a significant advantage of the new variety over the standard variety ‘Nutans 553’ according to productivity on 0.25 t/ha (+11.0%) on average; according to 1000-grain weight on 2.4 g (+6.0%); according to grain number per 1 m2 on 270 grains (5.0%). The variety ‘Granik’ was distinguished by a higher straw (69.3 cm, which was 4.0 cm higher than that of the standard variety), by better resistance to lodging and to dust brand. Under artificial inoculation with spores of the local population of dust brand, the greatest damage to the variety was 9.9%, while the standard variety was 23.1%. There were no significant differences between the varieties according to ‘length of vegetation period’ (70–74 days), nutritional and energy value. There has been found that both varieties were characterized by a high protein percentage (15.6–15.9%). Since 2019, the variety ‘Granik’ has been introduced into the List of the State Register of the Russian Federation for the 8th (Lower Volga) region. In 2020 the variety was tested in production conditions at the Arkadak agricultural experimental station on an area of 50 hectares, where it produced 3.30 t/ha against the background of the variety ‘Yak 401’, which produced 2.60 t/ha on the same area.
