Molekulare Verwandschaftsanalyse von <i>Gaultheria</i>-Arten
Abstract
Molecular distance analysis for Gaultheria species
ZusammenfassungDas in Nordamerika beheimatete amerikanische Wintergrün (Gaultheria procumbens L.) wird auf Grund der auffälligen roten Scheinbeeren, der immergrünen Blätter und der guten Winterhärte als Herbstpflanzung in Deutschland immer beliebter. Seine Anfälligkeit gegenüber dem Pilz Colletotrichum gloeosporioides (Penz.) erschwert jedoch zunehmend den Anbau. Nach der Resistenzevaluierung von Gaultheria-Arten soll durch Artkreuzung Resistenz oder Toleranz gegenüber C. gloeosporioides auf Gaultheria procumbens übertragen werden. Die Chance auf eine erfolgreiche Artkreuzung sinkt mit steigender genetischer Distanz drastisch. Deshalb sollen mit einer molekularen Distanzanalyse relativ eng verwandte Gaultheria-Wildarten ermittelt werden.

Abstract
Gaultheria procumbens L. originating from northern America is more and more popular on the German market because of its red berry-like fruits, its evergreen leaves and its good winter hardiness. Its great susceptibility for Colletotrichum gloeosporioides (Penz.) made it more complicated in the last years to cultivate it in Germany. After an evaluation of resistance, the aim is to cross a wild species with Gaultheria procumbens to get a resistant cultivar. The chance for successful crosses between different species decreases with increased genetic distance. Therefore molecular distance analysis was made to identify wild species with relatively close relation to Gaultheria procumbens.
Keywords: Gaultheria procumbens L., Colletotrichum gloeosporioides (Penz.), distance analysis
