Fields of Specialization

Foliage breeding has been focused on several important tropical ornamental genera including Aglaonema , Anthurium , Dieffenbachia and Spathiphyllum . Studies included factors affecting flowering, seed set, growth and inheritance of important horticultural traits. We have also just initiated a Syngonium breeding program.
