Abstract: The objective of this work was to verify the nine‑hole system efficiency in the evaluation of common bean (Phaseolus vulgaris) carioca-type progenies for plant architecture. Ninety-seven progenies were evaluated in the F2:3 and F2:4 generations in an randomized block design, with 20 replicates, and nine plants per plot, in which the central plant was evaluated, and the eight neighbor ones were considered together as the control. The evaluated traits were: grain yield per plant, architecture and lodging. The joint selection index (Zij) for the three characters was obtained through the sum of the standardized values per plot. Data were submitted to the analysis of variance, and from the mean square expected values, the components of variance were estimated. It is possible to identify more upright plants using the nine‑hole system, in segregating common bean populations. This system allows for high estimates of experimental accuracy and heritability.
