Item An interdisciplinary approach for evaluating beverage quality in Coffea canephora(Academia Brasileira de Ciências, 2025-05-09) SOUZA, LUCIMARA C. DE; FERRÃO, MARIA AMÉLIA G.; FONSECA, AYMBIRÉ FRANCISCO A. DA; VOLPI, PAULO SÉRGIO; COMERIO, MARCONE; PEREIRA, LUCAS L.; CARVALHO, JOSÉ AUGUSTO M.; SARAIVA, SÉRGIO H.; PINHEIRO, PATRÍCIA F.; SILVA JÚNIOR, ADELSON L. DA; SOARES, TAÍS CRISTINA B.The objective of this study was to assess the quality of Conilon coffee (Coffea canephora) based on agronomic, physicochemical, sensory profiles, and molecular markers. The dataset comprises 107 genotypes from the Incaper breeding program, evaluated in Marilândia, ES, Brazil. A total of 30 traits and 14 SSR markers were examined, revealing significant genetic variability. Most genotypes exhibited a medium June harvest cycle, uniform ripening, medium-sized beans, high processing yield, and a high percentage of flat and peaberry beans. Physicochemical variables, total titratable acidity, and potassium leaching contributed significantly to the observed variability. Chlorogenic acids (4.82%) and caffeine (2.58%) were the most abundant bioactive compounds. In sensory evaluations, 34 genotypes received scores exceeding 80. 13 markers were recommended for future association mapping studies to identify QTLs influencing the traits evaluated. Results identified genotypes with potential to maximize heterosis and genetic diversity in advancing generations. Among the evaluated genotypes, 34 were identified as promising due to their high sensory scores (≥ 80 points) and favorable agronomic, physicochemical, sensory, and genetic traits. The progeny HS17 stood out as the most divergent in agronomic and genetic traits compared to the other genotypes.Item Molecular characterization of parents and hybrid progenies of conilon coffee(Academia Brasileira de Ciências, 2021) Souza, Lucimara C. de; Ferrão, Maria Amélia G.; Carvalho, Rodrigo D.; Ferrão, Romário G.; Fonseca, Aymbiré F. A. da; Pinheiro, Patrícia F.; Soares, Taís C. B.The objective of the present work was the molecular characterization of 11 parents and 101 hybrid progenies of conilon coffee, obtained through diallel crosses from the breeding program of the Instituto Capixaba de Pesquisa, Assistência Técnica e Extensão Rural (Incaper, ES, Brazil). The analyses were performed with 18 Simple Sequence Repeat (SSR) molecular markers, obtaining a total of 32 alleles. SSR markers were classifi ed as moderately informative (PIC = 0.37), being effi cient in characterizing individuals. High genetic diversity was verifi ed in the 112 genotypes, based on the greater values of observed heterozygosity about to the expected heterozygosity (0.55 and 0.44, respectively), negative values for the fi xation index (F) (-0.14), and the formation of distinct groups by UPGMA. These results indicate high genetic variability among the conilon coffee genitors, which remained similar and persisting in the progenies. The average dissimilarity between parents was 0.29 and between progenies 0.34. The progenies 38 and 40 and the parent P11 were considered the most divergent in the study. The genetic variability found can be explored in the genetic breeding of the conilon coffee and guide crossings between diversifi ed and compatible genetic materials, for the composition of novel cultivars for the state of Espírito Santo.
