Resistance of Hordeum chilense against loose smuts of wheat and barley (Ustilago tritici and U-nuda) and its expression in amphiploids with wheat

摘要

P>Hordeum chilense is wild barley with high potential for cereal breeding purposes given its high crossability with other members of the Triticeae tribe. It is resistant to loose smuts of wheat (Ustilago tritici). The resistance is expressed in xTritordeum amphipoids, offering perspectives for its utilization both in tritordeum breeding and for its transfer to wheat. H. chilense and tritordeums are also resistant to barley loose smut (U. nuda).
