These programs provide training in all aspects of Plant Science including agronomy, biodiversity, biotechnology, crop quality, horticulture, plant breeding, plant ecology, plant pathology, plant physiology, and weed science. Many members of non-university institutions on campus, including Agriculture and Agri-Food Canada and the Plant Biotechnology Institute/NRC are Adjunct Professors.Graduate students may also carry out their thesis research in these institutions.

A dual degree Ph.D. program in Plant Sciences is offered in partnership with the United Graduate School of Agriculture Sciences (UGAS), Iwate University, Japan. A dual degree program allows students to pursue graduate studies at two universities, satisfying both institutions' admission and degree requirements, and a thesis co-supervised by faculty at each institution. Students receive a degree from both universities. Students should visit the Plant Sciences website or contact the college for further information
