They are known as chromosome pairs 1 through 22. Potatoes have been cultivated by selective breeding method in more than two hundred varieties including some unusual potato types including Purple peruvian, Red rose Russian banana, Charlotte and Adirondack blue. The molecular basis for traits in strawberry have mostly been identified using these techniques, yet few of these published reports describe natural sources of genetic variation that can be exploited by breeders. The authors identified genome sequence most closely resembling modern day F. nipponica, implying that ancestors of this species (that were sympatric with F. iinumae in Japan) gave rise to proximal tetraploid genotypes in neighboring China. & Bringhurst, R.
