This catalog aims to present information for coffee producers and anyone working with coffee plants about how different varieties can be expected to perform under ideal conditions.

Of course, coffee is not always grown under ideal conditions. Factors such as environment, altitude, soil nutrition, weather, the age of the tree, and farm management practices can significantly affect a coffee’s yield, quality, and health.

Because of this, it is impossible to give absolute data about certain aspects of a variety’s performance (for example, cup quality or yield). In those cases, we use Caturra, a common variety across Central America, as a reference. If a farmer knows how Caturra would perform on their farm, given their particular climate, soil, and farm practices, they should be able to measure the relative performance of other varieties against that knowledge.

The intention of this catalog is that those working with coffee should be able to make informed decisions about which variety will work best for their situation and needs.


Variables


Yielding Potential

How much fruit will the coffee tree produce?
Low, Medium, Caturra-like, High, Very high


Year of First Production

When will the tree produce its first fruit, as compared with Caturra
Early, Average (=Caturra), Late


Ripening of Fruit

At what time in the harvest season will the tree fruit ripen?
As compared with Caturra—Early, Average (=Caturra), Late, Very late


Optimal Altitude

What is the altitude at which quality and agronomic performance potential is maximized? This especially takes into account the variety’s expected cup quality and tolerance of coffee leaf rust. During the Central American leaf rust outbreak of 2012, the disease began showing up at higher altitudes than had previously been observed. Suggested altitudes for most leaf-rust-susceptible varieties have therefore been revised higher.


Coffee Leaf Rust

Is the plant susceptible to leaf rust?
Resistant, tolerant, susceptible

Coffee rust is a foliar disease of coffee caused by the fungus Hemileia vastatrix that cause defoliation and may result in severe crop losses.


CBD (Coffee Berry Disease)

Is the plant susceptible to CBD?
Resistant, tolerant, susceptible

CBD is a coffee disease that affects the fruit. It is caused by the fungus Colletotrichum kahawe. Currently, CBD is not present in Central America. However, it is included here because it will be important for farmers to have should the disease spread to the region.


Nematodes (Meloidogyne spp. or Pratylenchus spp.)

Is the plant susceptible to nematodes (specifically the species Meloidogyne spp. and/or Pratylenchus spp.)?
Resistant, tolerant, susceptible

Nematodes are microscopic animals which infect the plant roots and can cause wilting and death of the plant.


Bean Size

How big are the coffee beans?
As compared with Caturra—Small, Average (=Caturra), Large, Very Large


Leaf Tip Color

What color are the tips of new leaves?

Green, Light Bronze, Bronze, Dark Bronze, Green or Bronze


Cherry to Green Bean Ratio (Outturn)

What is the size of the bean in relation to the fruit?
As compared with Caturra—Low, Average (=Caturra), High, Very High


Quality Potential Expressed at High Altitude (>1200m)

What is the potential for quality of this variety when grown at higher altitudes?
Very Low, Low, Good, Very Good, Exceptional


Planting Density

What spacing should you use for planting this variety?
Bourbon-like (3000-4000 a/ha), F1 hybrid-like (4000-5000 a/ha), Caturra-like (5000-6000 a/ha)


Nutrition Requirement

How much nutrition (e.g., compost, fertilizer) does this plant require?
Low, Medium, High, Very High


Stature

What is the growth habit of the plant (e.g., is the plant tall or compact)?
Dwarf, Tall


Breeder

If the variety was created by a breeder, what is the name of the breeder?


Registered

Is the variety registered in the international database of varieties, called the International Union for the Protection of New Varieties of Plants (UPOV)?


Available Through WCR Verified Program?

Is this variety available through the WCR Verified program?


Type/Group (Genetic Diversity)

Traditional American (descendent from Typica or Bourbon), Ethiopian landrace, Introgressed (Catimor/Sarchimor), F1 hybrid
