Winterhardiness in cereals is the consequence of a number of complex and interacting
component characters: cold tolerance, vernalization requirement, and photoperiod
sensitivity. An understanding of the genetic basis of these component traits should allow for
more-effective selection. Genome map-based analyses hold considerable promise for
dissecting complex phenotypes. A 74-point linkage map was developed from 100 doubled
haploid lines derived from a winter x spring barley cross and used as the basis for …
