Resumo
With globalization and easy access to information, a consumer market that is more aware and seeking higher quality coffees emerges. However, the production of these coffees has been harmed due to global climate change, thus requiring studies of techniques that can maximize the production of these coffees in the face of such changes. In this sense, the objective of this study was to evaluate the effect of dry and irrigated water regimes on sensory, physical and physicochemical variables in ten arabica coffee cultivars (Paraíso H 419-3‐3‐7‐16‐2; Paraíso MG / H 419-1; Paraíso H 419-3‐3‐7‐16-11; Hybrid Paraíso; Catuaí 144 SFC; Catuaí 144 CCF; Catucaí 24‐136; Catucaí 2-SL; Sacramento MG1 and Oeiras MG-6851) , in order to discriminate the best responses of genetic materials, aiming the production of specialty coffees in the transition zone to arabica coffee. The genotypes were evaluated in the field, in split plot design and randomized block design with three replications. The fruits of arabica coffee were harvested with 80% of cherries grains and processed via humid. Subsequently, the characteristics related to sensory, physical and physicochemical analysis of coffee samples were evaluated. The results showed the existence of variability for almost all the evaluated characteristics, with considerable influence of the genotypic effect. The Paraíso group genotypes showed great genetic variability for the physicochemical and sensorial variables for the dry and irrigated regimes. While the Catuaí group genotypes showed less variability for sensory characteristics in both cultivation regimes and for physicochemical characteristics in the irrigated regime. : For the sensory analysis, regarding the global note attribute, the Catuaí 144 CCF and Catuaí 144 SFC stood out for the Irrigated and Paraíso H 419-3-3-7-16-2 environment, Catucaí 24-137 and Paraíso H 419 -3-3-7-16-11 for the dry environment
