In this paper, we studied coffee bean yield, maturation, and other characteristics of special progenies of Arabica coffee (Coffea arabica L.) grown under high temperatures in a low altitude region in the state of Rondonia, Brazil. We evaluated 29 progenies developed by the Instituto Agronômico de Campinas ? IAC, namely, 24 F2BC2 progenies of Obatã (C. arabica with introgressions of C. canephora) x (C. eugenioides 4n x C. arabica), three F3 progenies of Catuaí x Glaucia, and two H419 lines. Seven cultivars were used as controls. A randomized block design was used with three replications, spacing of 3.0 × 1.0 m, and ten plants per plot. All the crop seasons showed a significant difference for the hulled coffee yield trait. In combined analysis, significant difference was detected among progenies, among controls, and in the progeny vs control contrast. In the average of the four harvests, hulled coffee yield was 29.30 bags ha-1. The F2 progeny Obatã x (Catuaí x EUG DP x MN) C.1594 stood out from the others with a mean yield of 47.37 bags ha-1. The cultivars received beverage scores from 40 to 62, ?rioysh? to ?hard? beverage classification, while the progenies had scores from 40 to 80, ?rio? to ?barely soft? beverage classification. In regard to the maturation cycle, eleven progenies were late (April), eleven intermediate (March), and seven early (February). For continuity of advancement of generations, 104 plants were selected, derived from 22 progenies with the best productive performance, late maturation cycle, and good beverage quality.

The principal aim of this study was to investigate the molecular mechanisms underlying the response to drought stress in coffee plants by different approaches. In order to indentify candidate genes involved in controlling drought tolerance in coffee plants, different strategies were followed in our laboratories. The first used the nucleic data generated by the Brazilian Coffee EST project to identify candidate genes (CG) by in silico analysis (electronic Northern-blot). Differential expression of these CG was verified in leaves and roots from drought-tolerant and susceptible clones of C. canephora var. Conilon by Northern-blot and quantitative PCR experiments. The second was based on the screening of macroarray membranes spotted with coffee ESTs which were hybridized separately with leaf cDNA probes of the same clones. Finally, 2D gel electrophoresis was also performed to selected proteins presenting differential accumulation in leaves of the same clones. These proteins were analyzed by MALDI-TOF-MS/MS leading to the identification of a new set of CG. Results concerning the identification of CG by these different approaches are presented and discussed. |
