Abstract

Rust is the main disease affecting Coffea arabica, the most economically important coffee species. The objective of this study was to analyze C. arabica cultivars with different levels of rust resistance, including bean size, raw bean appearance, final sensory scores (FSS), and aroma and taste nuances of the coffee cup. The experiment was designed in randomized blocks (RBD) with three replications and 20 treatments (cultivars), totaling 60 experimental plots. The rust-susceptible cultivars IPR 100, Rubi MG 1192, and Topázio MG 1190 were compared with 17 rust-resistant cultivars. Cultivars IPR 103, MGS Aranãs, and Saíra II presented the highest percentages of high sieves, highest scores of raw bean appearance, and low percentages of mocha-type beans. All cultivars had FSS above 82 and were classified as specialty coffees. The cultivars with the highest FSS (Arara and Catiguá MG2) showed a greater diversity of coffee cup aroma and flavor nuances. Rust-resistant Arabica coffee cultivars are promising for the physical quality of beans and have potential for the specialty coffee market.

抗锈蚀阿拉比卡咖啡品种在特种咖啡生产中的潜力

铁锈是影响咖啡的主要疾病，咖啡是最重要的经济品种。本研究的目的是分析具有不同防锈水平的阿拉比卡品种，包括咖啡豆大小、生豆外观、最终感官评分（FSS）以及咖啡杯的香气和味道细微差别。本试验采用随机区组（RBD）设计，共有60个试验区，共有3个重复和20个处理（品种）。将易感锈品种IPR 100、Rubi MG 1192和Topázio MG 1190与17个抗病品种进行了比较。品种IPR 103、MGS Aranãs和Saíra II表现出最高的高筛百分比、最高的生豆外观分数和较低的摩卡类型豆百分比。所有品种的FSS均在82以上，属于特种咖啡品种。FSS最高的品种（Arara和CatiguáMG2）表现出更大的咖啡杯香气和风味细微差别的多样性。抗锈阿拉比卡咖啡品种在咖啡豆的物理质量方面很有前景，并有潜力进入特种咖啡市场。
