Abstract
Two hundred and fifty doubled haploid lines were studied from a cross between two 2-row winter barley varieties The lines were evaluated for several characters in a field experiment for 3 years on two locations with two replications From a total of 431 RFLP probes 50 were found to be polymorphic and subsequently used to construct a linkage map Quantitative trait loci (QTLs) were determined and localized for resistance against Rhynchosporium secalis and Erysiphe graminis, for lodging, stalk breaking and ear breaking tendency, for the physical state before harvest, plant height, heading date, several kernel parameters and kernel yield The heritability of the traits ranged from 0.56 to 0.89. For each trait except for kernel thickness, QTLs have been localized that explain 5-52% of the genetic variance. Transgressive segregation occurred for all of the traits studied.
