Seed Biology

Gregory E. Welbaum is a professor in the School of Plant and Environmental Sciences at Virginia Tech and has taught both classroom and online vegetable crop classes for over three decades. His successful book Vegetable Production and Practices has been specifically written for classes about vegetable crops based an his personal experiences as a commercial vegetable grower and university researcher.Since 2004, Dr. Welbaum has taught an online class on vegetable seed production. This class has been offered to Virginia Tech students as well as international students as a continuing education course. In addition, Greg has previously taught modules on vegetable seed production for the Seed Production short course offered by Seed Biotechnology Center at the University of California, Davis.
