Prospects of selection for barley seed vigour as a precondition for stand emergence under dry condition

Popis výsledku v původním jazyce

Study evaluated a segregating population of doubled-haploid lines and malting varieties for seed vigour tested at a low temperature of 10°C and under drought stress of -0.2 MPa and -0.5 MPa. The vigour of the dihaploid lines from six variants (3 years x2 localities) was compared with four germination parameters obtained under the optimum thermal and moisture conditions The vigour of seeds of four spring varieties of malting barley and their mutual 12 combinations was assessed in two variants (1 year x2 locations). Higher precipitation sums in June and July, i.e. shortly before harvest, were reflected in a decreased vigour (r = -0.777 and r = -0.721). Higher air temperatures during the period of April -- July increased the vigour significantly (r = 0.741). Correlation between the vigour and the germination parameters (r = 0.454 -- 0.539) was higher than in case of these germination parameters and the germination capacity (r = 0.266 -- 0.351). The relationship between the vigour of par
