Fields of Specialization

The major areas of specialization in the tropical ornamental foliage breeding program include:  studying the breeding systems of tropical ornamental plants including Aglaonema, Dieffenbachia, Epipremnum, Philodendron and Anthurium.This includes researching environmental and chemical factors affecting flowering and seed production, growth of hybrids, and genetics of important ornamental traits. Tissue culture techniques have been used to rescue embryos, induce polyploidy and propagate new hybrids.  We are using tissue culture for genetic transformation research with Ficus and Epipremnum. Irradiation has been used to induce mutations with Philodendron and Epipremnum. Hybrid and mutation selections are propagated and tested for performance before being considered for release.
