Abstract

  1. 1.

    The results presented here support the assumption that the potato species Solanum tuberosum is a true autotetraploid.

  2. 2.

    The results further show an unexpected correlation between the tuber colour type 2 (colour in the parenchymatic tissue underneath the skin, colourless periderm or skin) and flower colour, presumed to be due to the colour genes R and F, respectively (together with the complementary factor D). Both these factors are found to occur independent in other cases, producing varieties with red tubers and white flowers and such with white tubers and coloured flowers. Pimpernel is the first variety found to show this complete (or almost complete) linkage of the colour genes for tuber and flower. The variety Ringerikspotet very probably represents a case of repulsion of the factors R and F, the F factor being located in another chromosome than the two R-factors, with very little crossing-over occurring between the loci of R and F.
