Department of Horticultural Sciences

Department website: http://hortsciences.tamu.edu/

Head: A. Dhingra

Graduate Advisor: P. Klein

The graduate programs of the Department of Horticultural Sciences are designed to prepare individuals for careers in research, teaching, extension and industry. Research-oriented programs in the areas of fruit/nut/vegetable breeding, production and processing; ornamental horticulture/nursery crops; post-harvest physiology; greenhouse/floriculture production, marketing and economics; plant-microbe interactions; viticulture/enology; genetics/genomics; and plant physiology are available to students. Supporting work may be required in several related fields such as chemistry, biology, plant pathology, plant physiology, entomology, soils, genetics, nutrition and agricultural engineering. The specific objective of the individual student will guide his or her committee in the choice of courses from the departments mentioned above and others in special cases. More information on specific programs and faculty can be found at http://hortsciences.tamu.edu/graduate-programs/.

Programs of study leading to the Master of Agriculture, Master of Science and Doctor of Philosophy degrees are available.
