Abstract

Cultivated gerberas are among the top five most important cut flowers in the global floricultural trade and are also widely grown as flowering potted or garden plants in many countries. Gerbera breeding over the last 50 years has resulted in the development of numerous clonal cultivars and seed-propagated F1 hybrids. Breeding objectives for cut-flower, pot, and garden-type gerbera cultivars differ to some extent, yet bright flowers in multiple colors, flower types and coloration patterns, early and continuous flowering, high flower quality, high flower count or yield, tolerance to biotic and abiotic stresses, and strong plant performance are important for all types of gerberas. Hybridization and inbreeding have been the primary approaches used in gerbera breeding; they will continue to play a decisive role in further improvement of gerberas. In recent years, powdery mildew resistance, Botrytis resistance, leafy stems, twisted petals, and other novel characters or characteristics have been discovered in gerbera. Genetic, genomic, and molecular studies over the last 20 years have led to the development of a number of new tools and resources for gerbera breeding, including molecular markers for powdery mildew and Botrytis resistance, genetic linkage maps for local regions and the whole genome, candidate genes for flower types and disease resistance, cloned resident genes for anthocyanin synthesis and regulation, genome and transcriptome sequences, and gene transfer technologies. It is expected that as these and other new traits are incorporated into new cultivars and new breeding tools are widely adopted, gerbera breeding will reach a new height.
