Berry set, and average number of seeds/pollination and of seeds/berry from 3x × Tbr-4x crosses involving triploid (2n = 3x = 36) F1 hybrids and tetraploid (2n = 4x × 48) genotypes

Each 3x female parent was crossed with four different 4x male parents (varieties Tollocan, Blondie, Carmine, and clone Wis 482). No significant differences were found between crosses involving the same 3x female parent, so results were pooled across Tbr pollen parents.
†
The number of berries with seeds is reported in parentheses.
‡
Only fruits with seeds were considered.
