Geographic Genetic Variation in Black Cherry

Geographic genetic variation for survival, tree growth, and black knot disease susceptibility in a five-year-old black cherry provenance test was examined for relationships with three geographic and eleven climatic variables. Tree growth varied clinally; sources from near the Gulf and Atlantic coasts grew faster than interior sources when planted in central Mississippi. Annual cooling degree days and the amount of precipitation during the summer provided the best explanation of the observed patterns of geographic genetic variation. Seven geographic subregions of closely related provenances with distinct characteristics were identified. Additional keywords: Prunus serotina, provenance test.
