ABALAK MID-RIPENING CULTIVAR OF SPRING BARLEY

Abstract

There are presented morphological, biological and economic characters and properties of a new spring barley cultivar called Abalak recommended to be used for forage and food purposes. The cultivar is a result of joint cooperation between the Research Institute of Agriculture for Northern Trans-Ural (Tyumen Region) and the Krasnoyarsk Research Institute of Agriculture. The cultivar Abalak was obtained by hybridization followed by individual selection from the hybrid population Y-53-8515 × Ca 46925. It is mid-ripening, with the growing period from sprouting to wax maturity of 71 days on the average ranged from 61 to 85 days that was studied during competitive variety trial at the Research Institute of Agriculture for Northern Trans-Ural in 2008-2014. The cultivar is of medium height ranged from 71.6 to 102.8 cm and averaged 86.8 cm as compared to the standard Acha with its 79.1 cm, resistant to lodging. For the years of study, the average grain yield made up 5.88 tonnes per ha with 5.20 in the standard Acha. The maximum yield of 7.70 tonnes per ha was obtained in 2010. The cultivar has a sufficiently high coefficient of cereals (Kkhoz = 39.4%). It forms large kernel (thousand-kernel weight for years of competitive variety trial was 47.3 g on the average). Technological properties of grain are at the level of the standard Acha. The cultivar is moderately resistant to spring-summer droughts. It has been put into the State Register of Breeding Achievements since 2013 to be cultivated in the 4, 10 and 11 regions of the Russian Federation.
