Abstract
The Coffea canephora species has been gaining prominence in national coffee production due to its high productive potential, adaptability, and beverage quality potential. Productive genotypes and clones of Coffea canephora with sensory quality adapted to irrigated systems in the Savanna region are pressing demands, aligned with technological innovation. In this context, the aim of this study was to characterize Coffea canephora (Conilon) clones based on agronomic and chemical traits of the beans and to assist in selecting promising materials for use in the genetic improvement program of irrigated Coffea canephora in the Savanna. During the 2019/20 and 2020/21 harvest seasons, 33 and 35 Coffea canephora genotypes, respectively, were evaluated for productivity, morpho-agronomic traits, and concentrations of chlorogenic acid, sucrose, caffeine, citric acid, and trigonelline in raw beans. The data were subjected to cluster analysis based on the Canberra genetic distance matrix, and grouping was performed using Ward's method. The means were subjected to non-parametric univariate analysis using the Kruskal-Wallis test. In the first year, five groups were defined, with Group G1 showing the best rank numbers for the evaluated traits. In the second year, six groups were identified, with Group G6 standing out for morpho-agronomic traits associated with productivity and Group G5 excelling in the levels of chemical compounds evaluated, as well as productivity and physical grain characteristics. The genotypes L3.L16.P6 (22) and L4.L25.P123 (31), present in the groups that stood out in both years, were identified as promising, showing high potential for the genetic improvement program of irrigated conilon coffee in the Savanna, in both morphoagronomic and grain quality aspects.
