Abstract
The Kalanchoë genus comprises mainly succulent plants native to Madagascar and East and South Africa. The most important species in the genus is Kalanchoë blossfeldiana that gave rise to the majority of commercial cultivars. Kalanchoë plants are used as potted plants due to abundant flowering, desired longevity of individual flowers, excellent postharvest performance, and low-care requirements. The genus is also increasingly used as outdoor plants and cut flowers. Nowadays, Kalanchoë is ranked as the second most popular potted plant in Europe with annual turnover of 67 million euros in 2016. The breeding efforts in the genus focused mainly on K. blossfeldiana and started in the 1930s with an objective to develop compact cultivars with diverse flower color. Currently, the improvement of Kalanchoë cultivars is accomplished through intraspecific crossbreeding, interspecific hybridization, and genetic engineering. The modern breeding aims consist of a vast list of traits including morphological characteristics and postproduction longevity while minimizing negative impacts on the environment.
