Název v původním jazyce

Genetic diversity of BYDV resistant barley cultivars determined by molecular markers

Popis výsledku v původním jazyce

Genetic diversity was studied in 24 selected spring and winter barley cultivars, that showed a high or intermediate level of resistance in field infection tests in 1994-1997. The majority of lines carrying the Yd2 resistance gene originated from BYDV nurseries of CIMMYT and ICARDA. Microsatellite (SSR) and AFLP analyses were used to study the diversity of the collection. Resulting dendrograms and principal component analysis (PCA) divided the accessions into several groups, but no clear-cut separation between Yd2 and non Yd2 germplasm could be observed. Most Yd2 genotypes representing American cultivars were grouped together, whereas other Yd2 lines of CIMMYT and ICARDA were intermingled with non-Yd2 genotypes and susceptible checks. Czech spring malting barley cultivars were clearly separated by PCA.
