BERGO, Celso Luis; PEREIRA, Rita de Cássia Alves  and  SALES, Francisco de. Evaluation of Arabica and Robusta coffee genotypes in the state of Acre. Ciênc. agrotec. [online]. 2008, vol.32, n.1, pp.11-16. ISSN 1413-7054.

This work aimed to introduce and evaluate 40 coffee genotypes of Coffea arabica e Coffea canephora species in soil and weather conditions of Acre and had as main goal to provide cultivars to coffee producers with better potential of production. It was evaluated the genotypes Icatu, Bourbon, Mundo Novo, Catuaí, Obatã e Catimor from Coffea arabica species and genotypes Conilon and Robusta from Coffea canephora species. The genotypes were originated from Instituto Agronômico de Campinas (IAC) and Embrapa Rondônia. The study was carried out in the experimental field of Embrapa Acre, Rio Branco, AC from 1995 to 2004 following a randomized block design, with 5 replicates. One studied characteristics such as yield, height, plant diameter and vigor. The best genotype of Coffea arabica species, Icatu group, showed to be the Icatu-PR-182039-1(IAC H 4782-7-788), which yielded 34 sacks/ha of clean coffee; right after came Icatu IAC-4041, Icatu IAC-2945, Icatu IAC-2944-MT, Icatu IAC- 4040 and Icatu IAC-4046 with mean yeld from 20 to 26 sacks. For Catuai group, the best genotypes were Obatã IAC 4275, Obatã IAC 1169 e Catimor IAC 4466 with mean yield of 49, 45 e 37 sacks per hectare of clean coffee respectively. In the Canephora species were evaluated eigth genotypes of conilon and robusta which did not show significant difference among them related to yield, although it was observed a difference of 7 sacks/ha more for the gentotypes IAC 66-3 when compared to the local Conilon. In this group it was noted drought stress during the dry season (July/August) for all the genotypes.
