Resistance sources of barley yellow dwarf virus in barley and their utilization in barley breeding

Original language description

The resistance to Barley yellow dwarf virus (BYDV) by barley cultivars, breeding lines, and resistance sources has been tested in field trials in RICP Prague-Ruzyne since 1992. Most spring and winter barley cultivars grown in Central Europe have been found susceptible or very susceptible to infection with PAV strain prevalent in this region. Among spring barleys, only the cultivars Malvaz, Atribut, and Madras were found to be moderately resistant to BYDV. Moderate resistance was also detected in the winter cultivar Perry from the USA and Sigra from Germany. High resistance levels were associated with presence of Yd2 gene in spring and winter barley. PCR diagnostic markers YLM and Ylp were used to identify this gene. The results of field tests and genetic analyses in winter barley corresponded with marker analyses only when the Ylp marker was used.

Zdroje rezistence ke žluté zakrslosti ječmene a jejich využití ve šlechtění ječmene

Czech description

Odolnost k viru žluté zakrslosti ječmene u odrůd, novošlechtění a zdrojů rezistence byla testována v polních pokusech ve VÚRV Praha- Ruzyně od roku 1992.Většina ozimých a jarních odrůd pěstovaných ve střední Evropě je náchylná nebo velmi náchylná k BYDVkmenu PAV. V rámci jarních ječmenů pouze odrůdy Malvaz, Atribut a Madraz vykázaly mírnou rezistenci k BYDV. Mírná rezistence byla též detekována u odrůd ozimého ječmene Perry a Sigra. Vysoká úroveň rezistence je spojena s genem Yd2. Přítomnost tohoto genu je možno prokázat pomocí markéru Ylp.
