Abstract

In the North-West region, spring barley is the main grain fodder crop. The variety is an effective and most affordable means of increasing the harvest and quality of the grain. The studying selection material for breeding ensures success in the creation of new varieties. European varieties are characterized by resistance to powdery mildew, which is a limiting factor of breeding in the North-West region. This work aimed to find new sources of agrobiological valuable traits. In 2016-2018, which differed in weather conditions, 32 varieties of spring barley were studied on the field of the Pushkin Laboratory of VIR. As a result of studying a set of samples of the Western European ecological group, according to the main agrobiological valuable traits sources for breeding in the North-West region were identified: early maturing, semi-dwarf, large-grain variety – “Brucefield” (к-31555, parallelum, Germany); semi-dwarf, large-grain variety – “Brennus” (к-31331, nutans, France); middle-maturity, high-yielding, large-grain, semi-dwarf, resistant to lodging, with an adaptation coefficient more than 1 – “Niagara” (к-31334, nutans, France), “Tocada” (к-31341, deficiens, Germany), “Juhata” (к-31346, nutans, Germany), “KWS Alciana” (к-31348, nutans, Germany).
