A new spring barley cultivar Tanay

Abstract

There are given characteristics of a new spring barley cultivar Tanay bred at the Siberian Research Institute of Plant Production and Breeding, Branch of the Institute of Cytology and Genetics SB RAS (Novosibirsk Region) and included on the State Register of Breeding Achievements in 2014. The cultivar was derived from complex-hybrid population by means of individual selection. It is two-row barley of nutans type, mid-ripening, for fodder-grain purposes. Tanay has been developed by complex crossings using Jet and Bagan varieties resistant to loose smut, and it possesses the highest immunity to smut diseases. For the period of studies from 2010 to 2012, the maximum affection with the Ustilago nuda causative agent made up 1.1 percent in 2010. The new cultivar is characterized by resistance to loose and covered smuts against an artificial infectious background and high resistance to lodging, but somewhat yields to the standard Acha under conditions of sufficient moistening. It shapes a plant of medium (70-90 cm) height. For three years of study, its growing period was 72-80 days. Tanai formed its productivity of 3.7 to 5.3 tons per ha on average, surpassing Acha by 0.7-0.8 t/ha. As to biochemical characteristics, its grain quality is not inferior to the standard. The maximum yield of 7.49 t/ha was obtained in Kemerovo Region in 2013. The sowings of the new cultivar were registered in Krasnoyarsk Territory in 2015.
