  • SummaryRecent evidence indicates that potatoes were first domesticated in the central Andes of South America some 10,000 years ago. These belonged to the primitive diploid species,Solanum stenotomum, derived from the wild prototype,S. leptophyes. The tetraploid potato,S. tuberosum, arose through hybridization ofS. stenotomum with a second wild diploid species,S. sparsipilum. Further evolution took place with at least two other wild species,S. acaule andS. megistacrolobum, bringing genes for… CONTINUE READING
