The Departments of Fruit Crops, Ornamental Horticul- ture, and Vegetable Crops offer a joint program in horti- cultural science leading to the Master of Agriculture, Master of Science, and Doctor of Philosophy degrees, with specialization in fruit crops, ornamental horticul- ture, or vegetable crops. Areas of emphasis include crop physiology and bio- chemistry, seed physiology, crop breeding and genetics, environmental science, crop production and manage- ment, landscape horticulture, and postharvest physiol- ogy, biochemistry, handling, and horticultural taxonomy. New graduate students should have sound undergradu- ate training in horticulture or plant science which should include undergraduate credits in fruit crops, ornamental horticulture, vegetable crops, or general horticulture and botany, mathematics, chemistry, soils, entomology, and plant pathology or equivalent. Student interest and avail- able guidance and facilities will determine the area of emphasis within a given specialization for the thesis or dissertation problem. It is possible to conduct certain types of research for the Master of Science and Doctor of Philosophy degrees at one of the Agricultural Research and Education Centers or Agricultural Research Centers of the Institute of Food and Agricultural Sciences.
