Dwarf, Tall, Unknown, Not applicable

Leaf tip color

What col­or are the tips of new leaves?

Green, Bronze, Green or Bronze, Light Bronze, Dark Bronze, Unknown, Not applicable

Bean Size

How big are the cof­fee beans? For Ara­bi­ca ref­er­ence, Catur­ra = Aver­age, SL28 = Large, and Mar­a­gogipe = Very Large. 

Below Aver­age, Aver­age, Large, Very Large, Unknown, Not applicable

Yield Potential

How much fruit will the cof­fee tree pro­duce? For Ara­bi­ca ref­er­ence, Catur­ra = Good, and SL28 = Good

Low, Medi­um, Good, High, Very High, Unknown, Not applicable

Quality potential at high altitude

What is the poten­tial for qual­i­ty of this vari­ety when grown at high­er altitudes? 

Very Low, Low, Good, Very Good, Excep­tion­al, Unknown, Not applicable

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 to cof­fee leaf rust and cof­fee berry dis­ease. Opti­mal alti­tude depends on a far­m’s lat­i­tude — farms locat­ed close to the equa­tor will have high­er opti­mal alti­tudes than those far­ther north or south of the equator. 

First, locate your cor­rect lat­i­tude, then find the cor­re­spond­ing opti­mal altitude.

Lat­i­tude 5°N to 5°S

Low: 1000 – 1200m
Low-medi­um: 1000 – 1600m
Medi­um: 1200 – 1600m
Medi­um-high: >1200m
High: >1600m
Low-Medi­um-High: >1000m

Lat­i­tude 5 – 15°N or 5 – 15°S

Low: 700 – 900m
Low-medi­um: 700 – 1300m
Medi­um: 900 – 1300m
Medi­um-high: >900m
High: >1300m
Low-Medi­um-High: >700m

Lat­i­tude >15°S or >15°N

Low: 400 – 700m
Low-medi­um: 400 – 1000m
Medi­um: 700 – 1000m
Medi­um-high: >700m
High: >1000m
Low-Medi­um-High: >400m

Coffee leaf rust

Is the plant sus­cep­ti­ble to leaf rust? 

Cof­fee rust is a foliar dis­ease of cof­fee caused by the fun­gus Hemileia vas­ta­trix that caus­es defo­li­a­tion and may result in severe crop loss­es. Plant dis­eases are con­stant­ly evolv­ing. Note: A vari­ety that is resis­tant to a dis­ease today may not be resis­tant tomorrow.

Resis­tant, Tol­er­ant, Sus­cep­ti­ble, Unknown, Not applicable

Nematode

Is the plant sus­cep­ti­ble to nema­todes (specif­i­cal­ly the species Meloidog­y­ne spp. and/​or Praty­lenchus spp.)? Nema­todes are micro­scop­ic ani­mals which infect the plant roots and can cause wilt­ing and death of the plant. 

Resis­tant, Tol­er­ant, Sus­cep­ti­ble, Unknown, Not applicable

Coffee Berry Disease

Is the plant sus­cep­ti­ble to CBD? 

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, but it is a con­cern that the dis­ease will spread. Note: Plant dis­eases are con­stant­ly evolv­ing. A vari­ety that is resis­tant to a dis­ease today may not be resis­tant tomorrow.

Resis­tant, Tol­er­ant, Sus­cep­ti­ble, Unknown, Not applicable
