| Descrição: | This study aimed to evaluate the genetic relationships between morphological traits and the yield of Conilon coffee to identify key attributes for early selection using path analysis. The experiment followed Federer s augmented block design, with six blocks and five plants per plot, established in two environments: Alegre, at 700 m of altitude, and Cachoeiro de Itapemirim, at 140 m altitude, both in Espírito Santo State, Brazil. A total of 112 genotypes were assessed, using eight common cultivars as controls, at six, 12, and 18 months after planting. The genetic values for crop yield were obtained using mixed model methodology and evaluated through Deviance analysis. Correlation, collinearity diagnosis, and path analysis were performed between morphological traits and productivity. The five best genotypes for cultivation in both locations were T3, 28, 69, 100, and 107. The genotypes 28, T3, 69, 107, and 106 stood out in Alegre, while T3, 28, 69, 100, and 107 were the top-performing in Cachoeiro de Itapemirim. It was inferred that the genotype-environment interaction for productivity may be simple. The multicollinearity analysis played a crucial role in eliminating traits that inflated the model. For the early selection, breeding programs should prioritize the number of leaves, NDVI readings, and measurements of canopy diameter and height. |
