Introduction of gene mutations in coffee beans

From left to right: Kenya Round Bean, Elephant Bean, Kenya AA

Bourbon Pointu: Discovered in Bourbon Island in 1810, the bean body has changed from round to pointed, with only half the caffeine content; but the quantity is small and weak, and it is extremely precious (mostly cultivated in the laboratory).

Maragogype (or Elephant Bean): The best-known variety of tibeka bean, first discovered in 1870 in the Maragogype bean-growing region of the northeastern Brazilian state of Bahia, the bean is at least three times larger than the average Arabica, hence the name. The flavor of elephant bean is bad at low altitude, but it is better at high altitude, with mild sour taste and sweet fragrance.

Geisha: A derivative of the Tibika family, Geisha was exported from the Geisha Mountains in southern Ethiopia in 1931, and after many countries became unknown, it was transplanted to Panama in the 1960s, and it began to win frequently in cup competitions in 2005.

Kenya "SL28" and "SL34": French and British missionaries and researchers in the early twentieth century in Kenya screening, breeding out of Bourbon lineages, a century has been adapted to Kenya's high concentration of phosphoric acid soil, breeding Kenya's characteristics of sour spirit; top Kenyan coffee are from these two varieties, but transplanted elsewhere is tasteless.

Bourbon Amarello (Yellow Bourbon): A variety of Bourbon endemic to the Brazilian state of Sao Paulo, whose coffee fruits do not turn red when ripe and are orange-yellow. Other local bourbon derivatives were later found to have yellowed skins.

Caturra: A single genetic variant of bourbon discovered in Brazil in the 1950s. Long energy and disease resistance are better than bourbon, and no shade trees are needed; flavor is equal to or slightly worse than bourbon.

Pacas: Bourbon variety found in El Salvador, 1935 El Salvador coffee farmers Pacas transplanted the name Bourbon, to 1956 found that the results are higher than other coffee trees of the same kind, please identify the genetic mutation after identification.

Villa Sarchi: Bourbon variety first discovered in Costa Rica in the 1960s, often appearing in cup test excellence lists in recent years.
