Spud origin controversy solved

re better able to reproduce in long-day conditions, in contrast to Andean potatoes that were short-day adapted.

“The results of these studies are of interest not only to evolutionists but also for breeders. Years of effort were made to artificially recreate the European potato from Andean landraces yet it may have originated from Chile,?said Spooner. “If the true origin of the European potato was from Chile, rather from the Andes, it shows the value of plant evolutionary studies to understand and complement breeding programs?

Spooner and other scientists now plan to further investigate the origin of the European potato from DNA extracted from herbarium specimens of cultivated potatoes collected in Europe before 1845.

“The results of these studies are providing data to rewrite the history of the cultivated potato and will aid breeders to better interpret the true pedigrees of our modern potato,?said Spooner.
