In Vitro Propagation Strategies of Medicinally Important Berry Crop, Lingonberry (Vaccinium vitis-idaea L.)

Abstract

Lingonberry (Vaccinium vitis-idaea L.) is a health-promoting small fruit crop rich in antioxidant metabolites that helps to reduce the incidence of degenerative diseases. Being heterozygous, lingonberries cannot preserve genetic characteristics through seed propagation. Conventional vegetative propagation, although it produces true-to-type plants, is not economically viable. In vitro propagation can multiply plants much faster than conventional methods. A liquid cultures system under a bioreactor micropropagation system is of significant importance to increase the multiplication rates of in vitro-produced shoots. Enhanced vegetative growth and variation in biochemical constituents are observed in micropropagated plants. Clonal fidelity, although it may be a serious problem for commercial micropropagation, can be verified efficiently by molecular markers. The current review provides detailed and updated information on lingonberry micropropagation along with conventional methods and their effects on morphological, molecular and biochemical characteristics in micropropagated plants, filling the gap in literature.
