GRAIN QUALITY OF COLLECTION SAMPLES OF WINTER BARLEY

Abstract

In the creation of varieties that meet modern requirements of the brewing industry, an important role belongs to genetic sources. The study of the collection of the FSBSI Agricultural Research Center ‘Donskoyʼ in the department for barley breeding and seed-growing allowed identifying and recommending the sources of the main brewing and economic-valuable features and properties. The study was carried out in the years of 2014–2016. 77 varieties of winter barley with different ecological and geographical origin have become the objects of the study. The purpose of the study was to determine biochemical and technological properties of grain that meet certain requirements to brewing barley varieties. 31.2% of the studied varieties have been found correspondent to the trait ‘protein content in kernels’ (GOST 5060-86 ‘Brewing barley’). 7.8% of the samples have more than 60% starch in kernels. 57% of the collection varieties possess high extractivity (more than 78%). 13% of the studied varieties have husk content of kernels that meet the brewing requirements. 88% of all varieties correspond the GOST 5060-86 requirements in the trait ‘1000-kernel weight’. 64% of the samples significantly exceed productivity of the standard variety. As a result of the conducted correlation analysis there have been identified the correlations among the following traits: 1000-kernel weight – protein content in kernels; 1000-kernel weight – husk content in kernels; starch content in kernels – husk content; starch content in kernels – protein content in kernels. The best samples ‘Parallelum1916’, ‘Parallelum1923’, ‘Parallelum1813’, ‘Parallelum1820’, ‘315/Obzor’, ‘217-2(RF)’, Callao (USA), Rocca (Germany)
