| description | Molecular markers closely linked to interesting genes enable early, proper and fast detection of plant individuals with desired allele during backcross breeding, what can make plant breeding faster and cheaper. We are focused on molecular breeding of barley and wheat lines for disease resistance and some important quality traits. As acceptors of interesting genes we use especially elite Slovak and Czech cultivars and lines. After five backcross generations with the help of MAS new created lines carrying markers linked to desired genes undergo resistance, agronomic and technological tests. In breeding of winter barley for resistance to BaYMV/BaMMV viruses we use codominant STS and SSR markers linked to rym4 and rym11 resistance genes. Cultivar Romanze has been used as a donor of rym4 gene and landrace Russia57 as gene rym11 donor. In spring barley we are focused on transfer of Yd2 gene from landraces Shannon and Sutter resistant to BYDV by use of dominant ASPCR marker. We are also working on transfer of effective leaf rust resistance genes Lr19, Lr24 derived from Thinopyrum ponticum and gene Lr35 from Aegilops speltoides into hexaploid wheat by use of dominant STS and SCAR markers. Near isogenic lines with these genes are used in gene pyramiding to develop a single line with all three genes. By use of protein markers we develop near isogenic wheat lines for higher sedimentation values, higher dough strength and better breadmaking quality. These are lines with new combination of HMW glutenin subunits (21*, 7+8, 5+10) as well as wheat lines with new unknown HMW-GS and with new HMW-GS pair. |
