During three successive seasons, seeds from samples of Fireball Tomato seeds were subjected to adverse storage conditions for varying lengths of time to provide sub-samples which had four different levels of vitality but which were as nearly as possible identical in all other respects. These sub-samples were subjected to standard laboratory germination tests and were used in greenhouse plantings to produce plants for transplanted crops of tomatoes. They were also planted directly in field plots to produce field-seeded crops.
