Abstract
Abstract Kalanchoë cultivars rank as one of the most sold potted ornamental plants in the world. Among its key features that sustain high market interest are the long flowering period, abundance of flowers, thick and glossy leaves, easy maintenance and less water requirement compared to other potted plants. In breeding studies of Kalanchoë, plants with different flower colors such as white, cream, yellow, orange, red, pink and purple were developed. Moreover, double-flowered cultivars (comprising a large number of petals), more compact and cultivars with larger flowers were also obtained. Novel morphological characteristics are always in high demand in the market of ornamental plants. Increasing the variation in the gene pool with different species played a major role in the development of these characteristics. Nowadays, not only potted cultivars are launched but also cut flower cultivars have been developed and presented to consumers. Besides conventional breeding and interspecific hybridization, biotechnological methods, which have a promising future, are used to develop morphological characteristics of Kalanchoë.

Later, when Perrier returned to Paris, he transferred his collection to the garden
While cultivating the plants in Paris, he noticed that the plant from one location exhibited small yellow flowers; it showed the characteristics of K. globulifera as expected

In addition to scientists and researchers, private companies have continuously carried out breeding programs and developed cultivars with distinct characteristics These cultivars, which have been obtained using the K. blossfeldiana plant as the maternal parent, exhibited novel characteristics from the different species it was crossed with. Breeding in Kalanchoë has been carried out from past to present and generated a plethora of cultivars with multiple characteristics such as different colors, double colors, compact growth, a higher number of flowers per plant, a larger number of petals per flower, and long-term flowering (van Voorst and Arends, 1982; Izumikawa et al, 2007; Mackenzie et al, 2018). Succulent plants include around 60 different plant families such as Cactaceae, Agavoideae, Aizoaceae and Crassulaceae (Eggli, 2003; Royal Horticulture Society, 2021)
