 | In addition, the resulting 3n and 4n plants could be distinguished in the field by the use of a genetic marker for fruit color (3, 5). |
| While Shimotsuma and Matsumoto were able to separate 3n and 4n seed by thickness some 40 years ago, we questioned whether there had been inadvertent selection for thinner 4n seed since crossing blocks were direct-seeded, thus indirectly selecting for earliness in germination, emergence and development in tetraploid plants. |
| Triploid and 4n seed were found in essentially all weight groups, and there were no significant differences observed between 3n and 4n seed by weight. |
