Bred and introduced by Dr. William A. "Tex" Frazier
of Oregon State University and released in 1964. 'Willamette' was selected and stabilized from a complex between three tomato varieties; ('Campbell Soup 10' x 'Pennheart') x 'Queens'. 'Willamette' is resistant to radial cracking, and well adapted to the western valleys of the United States and Canada, New York, and Michigan. Each packet contains approximately 20 seeds.
