Possibility of selection for higher seed vigour of barley

Original language description

High seed vigour is a precondition for fast and homogenous field emergence and good malting quality in barley. The aim of this study was to (i) assess the possibility of selection for greater vitality of barley seeds (Hordeum vulgare L.) in conditions of drought and cold, (ii) to quantify the relationship between the size of the root system of the parental plants and seed vigour of progeny. The root system size was measured by its electrical capacitance directly in field. The seed vigour of four spring varieties of malting barley and their mutual 12 combinations was assessed in three variants (without drought stress, under drought stress of -0.2 MPa and -0.5 MPa), in two years (2012 and 2013) and on the two locations (Hrubcice and Zelesice). The vigour of 12 combinations from two locations was compared with vigour of their parents. Highly significant correlation was found in 2012 between the vigour of the mothers and their progenies (r = 0.832; P = 0.01), between that of fathers and of their progenies (r = 0.882; P = 0.01) and between the vigour of both parents and their progenies (r = 0.894; P = 0.01). The correlation between seed vigour combinations in F-3 generation (harvest 2012) and in F-4 generation (harvest 2013) was r = 0.886. This is another evidence for potential effective breeding for the seed vigour.
