Recent progress in barley improvement using wild species of Hordeum.
In this review we describe recent progress in barley (Hordeum vulgare) improvement through hybridisation with its wild relatives. We have focused on one species in the secondary genepool of cultivated barley, namely H. bulbosum. This wild species has desirable traits, such as disease resistance, that are worthwhile transferring to its cultivated relative. Progress has been achieved through developing partially fertile interspecific hybrids that have been selfed or backcrossed to barley. We present the results of cytogenetic and molecular analyses that have enabled us to characterise and produce agronomically useful recombinant lines obtained from the hybrids.
