WHY KENYAN FARMERS ARE GRAFTING RUIRU 11 WITH SL 28?

5/24/2022

4 Comments

 
Grafting is a horticultural technique whereby plant tissues are joined together to continue growing together. The upper part of the combined plant is called the stem, while the lower part is called the rootstock.
Picture
​The Ruiru 11 variety was released in 1985. The name of the variety has the prefix "Ruiru" which refers to the location of the Kenya Coffee Research Station where the variety was developed. The variety is not only resistant to CBD and CLR, but is also compact, allowing farmers to intensify production per unit of land.
The cultivar SL 28 was selected at the former Scott Laboratories (now the National Agricultural Laboratories, NARL located in Kabete) on the basis of a single tree, of the drought resistant variety Tanganyika selected in northern Tanzania in 1931. The prefix SL in the strain name stands for Scott Laboratories where the strain was selected. The variety is suitable for medium to high altitude coffee growing areas.
 
In an attempt to change "low organoleptic reputation" of Ruiru 11, farmers are grafting it with SL28. For the lower part,  they use the root of SL 28 which is much longer than that of Ruiru, and it can absorve more nutrients from the fertile Kenyan volcanic soils. For the top part, they use Ruiru 11, which is more resistant to coffee diseases than SL. They do this to gain the best of both worlds, the cup quality of the SL, with the strength and productivity of the Ruiru 11.

Is it advisable to uproot the SL 28 due to age or one can cut the tree then graft the shoot?
Or simply get an already young grafted seedling
