Caladiums are decorative aroids extremely valued for his or her engaging foliage that rivals the show of many flowers. Aroid is a standard title for a big species of vegetation within the Araceae household. This household of vegetation can also be typically referred to as the Philodendron or Arum household. There are over 100 genera and three,750 species of aroid vegetation, most of that are from the tropics.

Caladium vegetation develop properly in summer time warmth and rains and have a large range of leaf shapes, colours, and vein patterns which might be hardly ever present in different plant species. Essentially all commercially accessible caladium vegetation within the U.S. and on the earth are produced from tubers. Florida growers produce all the caladium tubers utilized by greenhouse growers, nurseries, landscapers, and gardeners throughout the U.S. and on the earth.

Since 1976, the University of Florida has supported a caladium breeding program, the one public program of its type on the earth, on the Gulf Coast Research and Education Center, to satisfy the wants of the Florida caladium trade and the environmental horticulture trade for brand spanking new caladium cultivars.

The program’s predominant breeding goal is to develop new and novel cultivars that may produce engaging and sturdy vegetation with many shiny, colourful leaves and with excessive tuber yield potential. The predominant breeding method used is hybridization of business caladium cultivars and breeding traces adopted by multiyear, rigorous choice and analysis.

According to Zanhao Deng, plant breeder and professor of environmental horticulture on the University of Florida Gulf Coast analysis and Education Center, the main target of his analysis has been to develop new cultivars with novel traits, improved illness resistance and plant efficiency, sterility, and different traits of curiosity to the environmental horticulture trade and its customers.

“The environmental horticulture industry is an important contributor to the economy, employment, and rural development; its needs have been the driving force of our statewide ornamental plant breeding program. So far, I have developed and introduced nearly 30 new caladium cultivars, including these four cultivars described in this article.”

Four new caladium cultivars, Dots Delight (UF-R1410), Firefly (UF-15-441), White Lightning (UF-15-21), and Spicy Lizard (UF-16-597), have been launched by the University of Florida caladium breeding program in 2020 and 2021. These cultivars have novel leaf colours, or coloration patterns, and are additionally improved in tuber yield potential, sunburn tolerance, and leaf well being. The cultivars have been additionally evaluated for his or her suitability in container plant manufacturing.

The analysis was printed in HortScience.
