Studies of genetic diversity have been performed on Coffea arabica varieties, which were found to be of low diversity but with retention of some residual heterozygosity from ancestral materials, and closely related diploid species Coffea canephora and C. liberica; [8] however, no direct evidence has ever been found indicating where in Africa coffee grew or who among the local people might have ...
Coffea arabica (/ ə ˈ r æ b ɪ k ə /), also known as the Arabica coffee, is a species of flowering plant in the coffee and madder family Rubiaceae.It is believed to be the first species of coffee to have been cultivated and is the dominant cultivar, representing about 60% of global production. [2]
The coffee genome was published in 2014, with more than 25,000 genes identified. This revealed that coffee plants make caffeine using a different set of genes from those found in tea, cacao and other such plants. [21] A robust and almost fully resolved phylogeny of the entire genus was published in 2017. [12]
Accounts differ on the origin of the coffee plant before its appearance in Yemen. From Ethiopia, coffee could have been introduced to Yemen via trade across the Red Sea. [ 14 ] One account credits Muhammad Ibn Sa'd for bringing the beverage to Aden from the African coast, [ 15 ] other early accounts say Ali ben Omar of the Shadhili Sufi order ...
List and origin of arabica varieties TIF. Coffee varieties are the diverse subspecies derived through selective breeding or natural selection of coffee plants.While there is tremendous variability encountered in both wild and cultivated coffee plants, there are a few varieties and cultivars that are commercially important due to various unique and inherent traits such as disease resistance and ...
Robusta is a species of flowering plant in the family Rubiaceae. Though widely known by the synonym Coffea robusta, the plant is currently scientifically identified as Coffea canephora, which has two main varieties, C. c. robusta and C. c. nganda. [2] The plant has a shallow root system and grows as a robust tree or shrub to about 10 metres (30 ...

According to legend, the coffee plant was discovered in Ethiopia by a goat herder named Kaldi around 850 AD, who observed increased physical activity in his goats after they consumed coffee beans. [10] The coffee plant was first found in the mountains of Yemen. Then by 1500, it was exported to the rest of the world through the port of Mokha, Yemen.
