In recent years, several new coffee cultivars recommended for different regions have been released. However, the performance of these varieties in many traditionally producing regions is unknown. Difference of climate and soil may jeopardize the productivity of the new cultivars and cause losses to farmers. The objective of this study is to evaluate the vegetative growth and productive genotypes of C. arabica in the conditions of the Northwestern Rio de Janeiro State, Brazil. The experiment was settled in 2007, in Panorama 1 Farm, located in the municipality of Varre Sai, RJ. Twenty-five genotypes of C. arabica were planted in a spacing of 2.5 × 0.8 m, using a completely randomized design with five replications and eight plants per plot. There were eight measurements of vegetative growth represented by plant height, stem diameter and number of plagiotropic branches. Assessments of productivity were also performed in years 2009 and 2010. There was a positive phenotypic correlation among vegetative characteristics and between vegetative characteristics and yield in the first harvest, while in the second harvest only the number of plagiotropic branches was positively correlated with yield. Up to date, the genotypes Catucaí amarelo 2 SL, Catiguá MG 02, Acauã, Palma II, Sabiá 398, IPR 103/ Iapar, IPR 100/Iapar, H 419-10-6-2-12-1, Catucaí amarelo 24 / 137, Iapar 59, Catucaí amarelo 20/15, H 419-10-6-2-5-10-1 and H 419-10-6-2-5-1 had the highest average yield after two harvests.

Porém, o conhecimento da resposta dessas variedades em outras regiões tradicionalmente produtoras é desconhecido, o que pode uma vez plantado nestas regiões, comprometer a produtividade dos genótipos devido às diversidades edafoclimáticas, causando prejuízo aos produtores. O presente trabalho tem como objetivo avaliar o crescimento vegetativo e produtivo de genótipos de C. arabica nas condições do Noroeste Fluminense do Estado de Rio de Janeiro. O experimento foi instalado em 2007, na Fazenda Panorama 1 localizada no município de Varre Sai - RJ. Foram avaliados 25 genótipos de café arábica, no espaçamento de 2,5 x 0,8m sendo o delineamento utilizado no experimento o inteiramente casualizado com cinco repetições, sendo oito plantas por parcela, totalizando 1000 plantas. Foram realizadas oito avaliações para desenvolvimento vegetativo utilizando a altura da planta, diâmetro do caule e o número de ramos plagiotrópicos. Também foram realizadas avaliações da produtividade do ano de 2009 e 2010. Houve correlação fenotípica positiva entre as características vegetativas e entre as características vegetativas e a produtividade na primeira colheita, sendo que, na segunda colheita apenas o número de ramos plagiotrópicos correlacionou positivamente com a produtividade. Até o momento, os genótipos Catucaí Amarelo 2 SL, Catiguá MG 02, Acauã, Palma II, Sabiá 398, IPR 103/Iapar, IPR 100/Iapar, H 419-10-6-2-12-1, Catucaí Amarelo 24/137, Iapar 59, Catucaí Amarelo 20/15, H 419-10-6-2-5-10-1 e H 419-10-6-2-5-1 apresentaram a maior produtividade média na avaliações das duas colheitas.
