Seed vigour is a precondition for early and homogenous field emergence of barley, in addition to effective malting. This study aimed to assess the selection of barley varieties by using seed vigour as the indicator. Seed vigour of barley (quantified as the germination percentage) was evaluated under drought (−0.2 MPa) and temperature stress (10°C). At two locations over a 3‐year period, 1 population of 133 Derkado × B83‐12/21/5 doubled haploid (DH) lines (and parents) was evaluated for seed vigour, of which 108 DH lines were assessed for three malting parameters. The relatively high values of vigour during the 3‐year period (overall average 94–95%) probably impeded high variations in genetic potential. A total of 27 DH lines of the 133 evaluated showed transgression for vigour (up to 98%) in comparison with the parents (Derkado: 96%; B83: 92%). In conclusion, caution should be applied when selecting for seed vigour, even in good crop years with high levels of seed vigour and low trait variations. Such selection might improve vigour, particularly in crop years with unsuitable weather conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
