F1 hybrids
First-generation crosses
F1 hybrids are the first-generation offspring of two distinct parent varieties, bred to combine desirable traits from each.
In agriculture and gardening, F1 seeds produce plants with predictable vigor, uniformity, and yield—but their offspring won't breed true, so growers must buy fresh seed each season.
F1 hybrid tomatoes dominate commercial production.
