Abstract
The transition from dormancy to germination
is crucial for malt barley in the malt house. Seed
dormancy is a quantitative trait and the depths of
dormancy controlled by environment/genetics remain
unclear. Quantitative trait locus (QTL) analysis was
conducted to evaluate the number, location and
phenotypic variation explained by QTLs from data
collected from different years, sites and germination
conditions in the Stirling 9 Harrington population.
QTLs on 4H, 5H and 6H could explain 25, 81
and 12 % of phenotypic variations, respectively.
Consistent QTLs were detected on 5HL and other
QTLs were subjected to growth or germination
conditions. Germination tests under light detected
more QTLs than in the dark. The QTL at 5HL were
more important for seed dormancy under the Mediterranean
environment and evidence showed at least
two genes controlling seed dormancy at 5HL.
