Genetic markers for doubled haploid response in barley

In order to analyse the genetic control of anther culture response in barley, a doubled haploid (DH) population from the cross between a medium responsive cultivar ‘Dobla’ and the model cultivar ‘Igri’ was produced. A linkage map was constructed with 91 markers. A sub-population of 41 lines was char...
