Coffea eugenioides?

Postby R Miguel Meza on Wed Jul 30, 2008 7:40 am

Does any one know anything about this species. according the genetic testing this (or it's recent ancestor) is the likely maternal parent of the arabica species (the other parent is currently accepted as Coffea congensis although some studies show it being more genetically similar to coffea canephera. the same studies show that C. Congensis and C. canephra are close gentically so perhaps the parent is actually an ancestor of both?)

I am curious as to what this species native range is and what it's appearance is. can't seem to find any pictures or valuable info online anywhere. It would see that atleast a few research stations around the world have this species in their collections. India and Brazil for certain.

I can't find any info that indicates that this species has ever been commercially grown, but if there is some where it was i'm curious to know about it and if anyone has tried it. according to some research papers i have come across it is said to have good aroma and flavor, much more so than other non arabica species, and is thought to be the source of arabica coffees fine cup quality. This has me very curious about this species.

I can find a little info on C. Congensis and based on some limited experience with congensis robusta hybrids it would seem that it is closer in cup quality to arabica having better acidity and less bitterness.

also does anyone know of any interspecific hybrids of C. eugenoides and C. congensis or C. canephera? if so is the resulting plant similar in appearance and taste to arabica?

it will be very interesting to see what further genetic testing reveals about coffee. And although i'm sure many are opposed to it, isolation of specific genes and transference of these to future hybrids is likely the future. I know there are very advanced breeding programs like this already and i'm sure their primary focus is yeild and disease resistence but I have to wonder what the possibilites would be if this knowledge was applied towards improved cup quality. If we could at some point in the future discover a gene that gives the geisha and other ethiopian varietals their citric quality or one that controls the amount of sugar production in cherries.

The only picture I've seen:

Also, it may be worth researching Coffea nandiensis, Coffea becquetii, Coffea intermedia and Coffea mufindiensis, which I have seen listed as a synonyms.

On a similar note, I recently read speculation that naturally occurring intergeneric hybrids with tetraploid individuals of Psilanthus ebracteolatus could have possibly contributed to the C. Arabica gene pool.

Here's some better info and pictures:

Also, this article might be worth purchasing. It deals with Eugenioides hybrids and their caffeine content.
