Kalanchoë Breeding: Past, Present and Future

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.

Bioactive Compounds from Kalanchoe Genus Potentially Useful for the Development of New Drugs

“…Additionally, regarding breeding programs, new cultivars with different characteristics of flower aspects (such as color, number and shape) are being created not only by means of conventional breeding, but also by using biotechnological methods. For example, gene transformation methods have been used in Kalanchoe , producing plants with shorter internodes, longer-lasting flowers, and late blooming (for a deeper reading, see [ 141 ]).…”

Flower morphology of selected species of genera Kalanchoe and Bryophyllum in Nigeria

“…Their flowers occur in clusters [5][6][7][8]. They are mostly perennials but can also be annual plants [9,10]. Kalanchoe species can be used as ornamentals around the world [10].…”

“…They are mostly perennials but can also be annual plants [9,10]. Kalanchoe species can be used as ornamentals around the world [10]. Species of Kalanchoe possess flowers that are terminal and seldom axillary flowers.…”

“…Their inflorescence are corymb, paniculate, or cymose. Petals are usually four in number, stamens eight in number, and carpels four in number [10].…”

Post-production Growth and Quality of Echeveria agavoides and Echeveria elegans Treated with Artificial Coloring

“…The main goal of these processes is to create innovative, distinguished and attractive features in the goods placed on the consumer market, which always welcomes novelties [3], and, thus, to add value to various products in the floral industry [4]. Over the last two decades, there has been a considerable rise in consumer interest in color variation in succulents both through genetic or phenotypic diversity [5], [1] and natural and artificial coloring processes [6].…”
