“…According to Ferreira et al (2013), as the size of the grains grow, more uniform is the batch to be processed, influencing directly the physical aspect of the product, being desirable in espresso machines for example, where the roasted beans are exposed to the consumer.…”

Through the pruning type 'esqueletamento' it was developed a technology for the management of trees called "Zero Yield" in order to keep the size of the crop and eliminate the harvesting in a low yield season, which usually compromises the earnings of the coffee grower. With this technology, the harvest takes place every two years, always in years of high yield season. This technology is highly dependent on climate, and genotype. Given this, the objective of the study was to select genotypes of Coffea arabica L. responsive to pruning type 'esqueletamento', with high productivity and high potential for quality of drink for specialty coffee production. The experiment was deployed in the Coffee Sector at the Universidade Federal de Lavras (UFLA) in December 2005 and after six crops, it has undergone the pruning type 'esqueletamento' in August 2014. 20 genotypes were evaluated, being 18 progenies in F 5 generation, derived from the cross between cultivars of the Catuaí Group with coffees of germplasm Icatu and germplasm "Hibrido de Timor" and two commercial cultivars as witnesses. (Tupi IAC 1669-33 and Obatã IAC 1669-20). The following characteristics were evaluated: productivity (before and after pruning), vegetative vigor, the incidence of leaf rust, dull fruits, sieve No.16 and above, grain type mocha, aspect, and quality of drink. The genotypes 9 (H516-2-1-1-18-1-1), 12 (H516-2-1-1-18-1-4), 16 (H419-3-4-5-2-1-3), 18 (H419-3-4-5-2-1-5) and the cultivar Tupi IAC 1669-33 were responsive to the 'esqueletamento', with productivity after pruning higher than the maximum reached before the adoption of the pruning. All genotypes with the exception of Catucaí Amarelo 24/137 showed potential for the production of specialty coffees.

“…The genotypes that presented a highest average productivity showed a smallest biennial effect, which was characterized by an annual alternation of high and low productivity. Bourbon Amarelo had low productivity; however, Ferreira et al (2013) observed that Bourbon genotypes exhibited satisfactory productivity and presented genetic variability within the group.…”

Agronomic performance of arabica coffee genotypes in northwest Rio de Janeiro State

ABSTRACT. Considering the productive potential of arabica coffee in the Rio de Janeiro State and the shortage of breeding programs for this species in the state, this study aimed to evaluate the vegetative and productive characteristics of 25 arabica coffee genotypes to indicate 1 or more varieties for the northwest Rio de Janeiro region. The experiment was in Varre e Sai, RJ, Brazil, and plants were planted in 2007 with a spacing of 2.5 x 0.8 m. Five plots were used, consisting of 8 plants per plot to measure vegetative growth, height, stem diameter, and plagiotropic branch number characteristics and productivity in the biennia 2009/2010 and 2011/2012. The classification by sieve was performed at harvest in 2011. The variables were subjected to analysis of variance and means grouped by the Scott Knott test at 5% probability, and the productivity was subjected to joint analysis of variance. Pearson's correlation coefficients between growth and productivity

“…A menor ocorrência de grãos tipo moca na variedade botânica Robusta pode estar associada a um maior polimorfismo do gene S, que expressa a autoincompatibilidade de C. canephora. Atualmente o percentual de grãos tipo moca não é considerado na avaliação da qualidade do café, entretanto é uma caracteristica desejada por proporcionar uma torrefação mais uniforme dos grãos (CARVALHO et al,2013). TABELA 2.…”

“…Segundo Ferreira et al (2013), a peneira média está associada a uma boa qualidade do café, que normalmente é negociado com maior valor de mercado. Laviola et al (2006) salientam a importância da peneira para identificação de variedades com maior potencial produtivo.…”

RESUMOEntre as diversas espécies de café identificadas, o Coffea arabica e o Coffea canephora, são as cultivadas comercialmente de maneira significativa. Na região Amazônica a principal espécie cultivada é o C.canephora que apresenta naturalmente duas variedades botânicas distintas o Conilon e o Robusta. Essas variedades possuem diferentes características em relação ao tamanho e a forma do grãos que são classificados de acordo com a retenção em peneiras com crivos de diferentes diâmetros. O objetivo desse trabalho foi quantificar ao longo de duas safras a peneira média (PM) e o percentual de grãos moca (PGM) de C.canephora. Para isso foram coletadas, amostras de 300 gramas de café de 112 clones, das variedades botânicas Conilon (68) e Robusta (18) e de híbridos intervarietais (26), provenitente do campo experimental da Embrapa Rondônia do município de Ouro Preto do Oeste -RO. Peneiras de crivos oblongos, de numeração 9 a 13 foram utilizadas para caracterizar os grãos tipo moca e as circulares de 12 a 19 para os grãos tipo chato. Observou-se que a PM não alterou sua média de um ano para o outro (14,75), diferente do PGM que apresentou média de 32,5 no 1º ano e 54,01 no 2º ano. A PM é uma característica que foi pouca influenciada pelo ambiente em comparação com o PGM que apresentou uma baixa correlação ao longo do tempo. As variedades botânicas apresentam expressiva diversidade genética para PM que subsidia a seleção de novas cultivares que reúnam uma série de característica favoráveis. PALAVRAS-CHAVE: Melhoramento genético, Qualidade, rondônia.
