Genealogical analysis of the diversity of spring barley cultivars released in former Czechoslovakia and modern Czech Republic

Popis výsledku v původním jazyce

Genealogical analysis was employed in studying the time course of changes in genetic diversity of spring barley cultivars released in former Czechoslovakia and the Czech Republic. Cultivars from different regions proved to significantly differ in distribution of dominant ancestor contributions, suggesting a specificity of original ancestors to different cultivation conditions. Temporal analysis showed that diversity tended to increase through decades. While new original ancestors were introduced in pedigrees, the number of local landraces and old cultivars gradually decreased. The losses accounted for about two-thirds of the local germplasm. Thus, a substantial increase in genetic diversity was accompanied by genetic erosion of the local spring barleygene pool of former Czechoslovakia. The coefficient of parentage averaged over all possible pairs of cultivars introduced in the Czech National List was estimated at 0.11. Genetic diversity of modern spring barley cultivars in CR is at ac
