Abstract – The objective of this work was to evaluate the production of
cuttings of Coffea canephora genotypes, in a new system for training mother
plants called “vertical clonal garden”. The proposed new system consists of
training coffee plants with only one shoot and without bending the main shoot,
so that the secondary orthotropic shoots, from which the clonal cuttings will
be taken, are formed across the length of the stem in the vertical direction.
The capacity for the production of cuttings of ten hybrid genotypes of coffee
plants was evaluated over ten production cycles. The 'BRS 2314', 'BRS 3213',
and 'BRS 3210' genotypes showed cutting production per cut of 425,000
cuttings per hectare, considered above the obtained average. The 'BRS 3193',
'BRS 2336', 'BRS 3220', and 'BRS 3137' genotypes were the least productive.
Coffee plants trained in the “vertical clonal garden” system can produce about
425,000 cuttings per hectare per harvest period or about 1.275 million cuttings
per hectare per year, over three harvest periods, with a greater ease in crop
management and treatments.

Resumo – O objetivo deste trabalho foi avaliar a produção de estacas de
genótipos de Coffea canephora, em um novo sistema de condução de plantas
matrizes denominado “jardim clonal vertical”. O novo sistema proposto
consiste da condução dos cafeeiros com apenas uma haste e sem o vergamento
da haste principal, de tal forma que as hastes ortotrópicas secundárias, de
onde serão retiradas as estacas clonais, sejam emitidas em toda a extensão
do caule, no sentido vertical. A capacidade de produção de estacas de dez
genótipos híbridos de cafeeiros foi avaliada durante dez ciclos de produção.
Os genótipos 'BRS 2314', 'BRS 3213' e 'BRS 3210' apresentaram produção de
estacas por corte de 425,000 estacas por hectare, considerada acima da média
obtida. Já os genótipos 'BRS 3193', 'BRS 2336', 'BRS 3220' e 'BRS 3137' foram
os menos produtivos. Cafeeiros conduzidos em sistema de “jardim clonal
vertical” podem produzir cerca de 425,000 estacas por hectare por corte ou
cerca de 1,275 milhão de estacas por hectare por ano, em três cortes, com
maior facilidade de manejo e tratos culturais da lavoura.
