Triploids of the common potato,Solanum tuberosum L.

Summary Triploid plants of the common potato (Solanum tuberosum L. group Tuberosum) were derived from crosses between tetraploid varieties and selected dihaploids. The ability to induce triploidy seems to be largely dependent on the genotype of the dihaploid parent. Morphologically there was very little difference between triploids and their tetraploid siblings. Yields of triploids could be equivalent to genetically similar tetraploids.
