Abstract
Disomic wheat/barley addition lines were developed from hybrids produced with the German two-rowed winter barley cultivar ‘Igri’ and the Ukrainan six-rowed winter barley cultivar ‘Manas’. The 2H, 3H and 4H disomic addition lines of winter wheat ‘Martonvásári 9 kr1’/winter barley ‘Igri’ produced in Martonvásár were identified using GISH, FISH and SSR markers. A disomic addition of the 1HS isochromosome was also identified. The 2H, 3H and 4H addition lines have been multiplied in the nursery and characterized morphologically. Backcross progenies were produced and identified with molecular genetic and cytogenetic methods from the Japanese wheat ‘Asakaze komugi’ × Ukrainan six-rowed winter barley ‘Manas’ hybrids. A deletion and a translocated chromosome facilitated the physical localization of microsatellite markers on chromosome 5H. So far the 4H disomic addition line has been identified from the fertile BC2 plants in this combination, but the development of other disomic additions is in progress
