Comparison of inheritance in tetraploid potatoes and polyploidy wild Solanum species
Feature | Species example | Segregation | Multivalent in meiosis | Chromatid segregation | Fertility | Key references | |
---|---|---|---|---|---|---|---|
Tetrasomic cultivars | tetraploid | S. tuberosum | Tetrasomic and variable | Yes | Possible | Low to medium |
Allard (1960) Bradshaw (1994) Ortiz and Watanabe (2004) |
Disomic species (4x, 6x) | polyploid | 4x: S. acaule, S. stoloniferum, 6x: S. demissum | Disomic | No | No | Very high | Watanabe and Orrillo (1994) |
