A chromosomal chimera in a plant of Lilium callosum with a complex translocation 1

1. The spectacle pattern is a white patch round each eye of an otherwise pigmented potato tuber. Genetically it is the heterozygote JjSP, II being self-coloured and jsPP white. 2. One self-coloured heterozygote has been detected and a rather consistent deficiency of spectacles in several families suggest that they may be fairly frequent (in the range 8-25 per cent. of heterozygotes). 3. Speculatively, it seems likely that jSPis compound.
