Abstract: Brazilian coffee cultivation was boosted over the last few decades
by the mechanization of various field operations. Considering the influence of
genetic factors on coffee harvesting efficiency, we aimed to evaluate the use of
mechanized harvesting characteristics as a criterion to select progenies derived
from ‘Icatu’ germplasm, previously evaluated for agronomic characteristics,
resistance to rust and cercosporiosis. We also investigated genotypic and
phenotypic correlations between semi-mechanized harvesting characteristics.
Ten progenies of Coffea arabica L. were analyzed in two experimental farms
during two consecutive harvests. Genetic parameters were evaluated to trace
selection strategies. Four progenies that were suitable for mechanization were
selected, supporting our hypothesis of the use of harvest characteristics as
selection criteria.
