Abstract
THERE are clear advantages in carrying out potato breeding at the diploid level, but it is likely that the expression of maximum productivity occurs at the tetraploid level1. One way in which diploids can be brought to the tetraploid level is by 2x–4x or 4x–2x crosses. It has long been known that a large proportion of the progeny of such crosses is tetraploid2,3, and it is generally recognised that unreduced gametes with the somatic chromosome number (2n) are produced by the diploid parent and these, with normal gametes (n) of the tetraploid parent, give tetraploid offspring.
