Seed vigor was evaluated as germination percentage at low temperature (10 °C) and drought (-0,2 MPa), and also as germination parameters (energy, rate and index). 133 double-haploid lines (DHL) and their parents were evaluated in six environments. The total variation consisted of 51% by environments, 8% by lines and 37% by their interaction. The better parents showed higher vigor when harvested in worse location. The other parameters were controlled similarly (34,7 -- 41,0% location, 24,9 -- 32,9% year and 8 -- 37% by the lines. The results can be used as support for breeding for higher grain vigor not only for better agronomic but also for higher malting value.
