The department participates in interdepartmental programs awarding the Master of Science and Doctor of Philosophy degrees with a major in plant and environmental science, genetics and in food technology.  The Ph.D. program requires the performance of original research leading to a dissertation.

Research concentrations are offered in molecular biology, plant breeding and genetics, tissue culture, weed science, photomorphogenesis, postharvest physiology, stress physiology, crop production physiology, landscape design and plant nutrition. Each student's degree program is tailored to his or her professional goals with the guidance of an advisor and graduate committee. All graduate students in horticulture must select an advisor before admission.

Timely topics in horticultural science. May be repeated for a total of four credits, as topics and instructors vary.   Prerequisite:  Permission of instructor.
