Qianjie-Kaddura introduction

Kaddura

Kaddura (Caturra) is a natural hybrid of Bourbon, which was further developed and widely cultivated by the Alcides Carvalho Coffee Center of the Agricultural Research Institute (IAC) in the State of Sao Paulo, Brazil. This variety has brought about profound changes to the coffee industry all over the world.

In 1937, IAC received seed samples from northeast Rio de Janeiro, Brazil. In a bourbon-planted coffee tree, a coffee plant with shorter height and shorter node distance has attracted the attention of local farmers. On the surface of the study, Kaddura is a natural hybrid of bourbon, which is derived from the mutation of bourbon single gene.

The single gene that Kaddura mutated controls the distance between the nodes between the branches and the height of the plant. So Kaddura has shorter plants and shorter nodes between branches than bourbon. Short plants are beneficial for coffee farmers to pick, and shorter nodes between branches can produce more fruit. These two factors lead to higher yield of Kaddura than bourbon.

Kaddura usually matures faster and is more disease-resistant than traditional Arabica varieties, so Kaddura is somewhat similar to the high-yield and disease-resistant version of bourbon.

At the same time, like bourbon, Kaddura is well adapted to most coffee growing environments, but performs best in areas with an altitude of 1200 to 2000 meters and an annual rainfall of between 2500 and 3500 millimeters. The higher the altitude, the better the quality, but the lower the output.

In fact, Kaddura is not the only mutant; similar mutants include El Salvador's Pacas (Pacas) and Costa Rica's Vera Saatchi (Villa Sarchi). Genetically speaking, in all cases, this mutation is very similar to bourbon.

Knowledge: Arabica coffee is generally thought to be originated from the Ethiopian plateau, widely distributed in the tropics, after repeated mutation and breeding, derived many varieties.

In short: Qianjie is a coffee research hall, happy to share the knowledge about coffee with you, we share unreservedly just to make more friends fall in love with coffee, and there will be three low-discount coffee activities every month. The reason is that Qianjie wants to make more friends drink the best coffee at the lowest price, which has been Qianjie's tenet for 6 years!
