UNKNOWN HEROES OF THE GENETIC DIVERSITY OF ARABICAS

1/16/2019

0 Comments

 
Kenya is probably one of the most advanced producing countries, in the study and experimentation with the genetic diversity of Arabicas, and is far ahead of important countries such as Ethiopia for example.

​On our last trip to Kenya we met the great "Dr. James", who works at the "Kenya Coffee Research Institute" station in Nyeri. In this place, he explained, how they are performing grafting of Ruiru 11 with SL 28, and the importance of its result for the future of the industry.
Grafting in Agriculture, is a technique where tissues of different plants are joined to continue their growth together. This technique seeks to obtain the best of each of the varieties. Generally in plant breeding, the greater the genetic distance between the two parents, the more "vigorous" the child will be (World Coffee Research).

​Ruiru 11 is a variety of high productivity and resistance to diseases. But the problem is that its root is too short, and it is not able to get enough nutrients from the rich African soil. This usually causes poor results in the cup, without the usual complexity of other varieties grown in Kenya.

In contrast, SL 28, is a variety, which as we all know, has an excellent cup quality, but it has low productivity and is susceptible to diseases such as Leaf Rust or CBD.

Dr. James and his team are grafting leaves of Ruiru11 (scion) with a root of SL 28 (stock), to create resistant varieties of high productivity, with the capacity to absorb more nutrients and hopefully, obtain a better quality in the cup .

​It is urgent that we begin to work together towards the development of new varieties and the increment the genetic diversity of this specie that we like so much.

Enjoy the genetic and organoleptic diversity of your Kenyan coffee!
