Horticultural Sciences


The Horticultural Sciences graduate program is dynamic and diverse, offering students the freedom to join research programs in molecular genetics, breeding, physiology/biochemistry, postharvest biology, crop production and nutrient management, organic and sustainable agriculture, or weed science.

Our dedicated research faculty and state-of-the-art laboratories, greenhouses, research farms, and research and education centers are strengths of our graduate research program.

When you join the Horticultural Sciences graduate program, you become a part of a team of faculty, students, and staff committed to the pursuit of original research in horticulture.

The Horticultural Sciences Program offers both postgraduate opportunities:


Explore the Horticultural Sciences graduate program, where you can pursue a Master of Science (thesis or nonthesis) or Doctor of Philosophy degree while working alongside expert faculty based on UF’s main campus and at Research and Education Centers across Florida. Find a research area that inspires you, connect with faculty who share your interests, and take the next step toward a career in horticultural science.

Master of Science Non-Thesis Option

This option offers additional training beyond the bachelor’s degree in a horticultural specialization. Essential elements of this program include a program of courses and a comprehensive written and/or final oral qualifying examination. There is no thesis requirement. A minimum of 30 credit hours of course work is required. Courses taken for program credit must be numbered 5000 or higher with at least 15 of these credits in the Horticultural Science major. With supervisory committee and college dean approval, 6 hours of 3000- or 4000-level undergraduate courses, taught outside the major department, may count toward the minimum requirements for the degree.

A minor may be chosen in an academic unit other than the major. If a minor is chosen, at least 6 credits of work are required in the minor field. Two 6-credit minors may be taken with the major academic unit’s permission. A 3.00 (truncated) GPA is required for minor credit. In addition, a representative from the department in which the minor is being received must be on the supervisory committee.
