Population genomics of Vaccinium vitis-idaea L. and links to environmental conditions, total phenolics, and antioxidant capacity in Newfoundland and Southern Labrador
Lingonberry, also called Partridgeberry in Newfoundland (Vaccinium vitis-idaea L.) is native to Eurasia, Greenland, Iceland and North America. Partridgeberry is well known for its nutritional benefits, making it increasingly important for cultivation. While cultivation in Europe is widespread, it is...

Lingonberry, also called Partridgeberry in Newfoundland (Vaccinium vitis-idaea L.) is native to Eurasia, Greenland, Iceland and North America. Partridgeberry is well known for its nutritional benefits, making it increasingly important for cultivation. While cultivation in Europe is widespread, it is only in developmental stages in North America. Knowledge of the genetic structure of wild populations, and its relationship with environmental conditions, phenolic content (TPC), and antioxidant capacity (AC) is necessary for the selection of desirable genotypes, but this knowledge is incomplete globally. Therefore, the genetic structure of 56 wild partridgeberry populations distributed across nine ecoregions of Newfoundland and Southern Labrador in Canada were investigated in the present experimental study. This thesis also evaluated the effects of environmental factors on the TPC and AC of partridgeberry leaves. By testing different variable levels, significantly higher TPC on leaves was found in individuals growing under elevated levels of surface water pH (>7).
