Expression Effects of CHI and CHS Genes and Colchicine Treatment in Yellow Flowered Cyclamen: a Review

Abstract

Nowadays, the field of entirely artificial hybrids raises ethical problems in the animal world and to a lesser amount in plants. Throughout the years, yellow Cyclamen has been particularly important for both breeders and passionate growers as being a peculiar color for this species. The possibility to artificially induce hybrids between species that can never normally cross it’s now achievable. This paper describes the possibility of obtaining high ornamental yellow flowered cyclamen, through chromosome doubling. The pollen and seed sterility can be overcome by doubling the chromosomes. In this sense, there are two full sets from each parent, resulting in a fertile hybrid, by introducing the in vitro culture into colchicine supplemented medium.
