The objective of this study was to morpho-agronomically characterize Urochloa sp. accessions from the forage collection of Embrapa Caprinos e Ovinos, aiming to identify the most divergent accessions to support the selection of materials better adapted to cultivation under semi-arid conditions. Fifteen Urochloa sp. accessions were used in a randomized block design with three replications and eight plants per plot, with a spacing of 0.5 m between plants and 0.5 m between rows. A uniformization cut (60 days after transplantation) was performed, followed by two subsequent cuts at intervals of 60 days, starting from the uniformization cut. The morphological characterization was initiated 12 days after the uniformization cut. The characterization of the accessions was performed based on 24 quantitative and qualitative morpho-agronomic descriptors of Brachiaria. The evaluations of fresh and dry matter productivity were performed following the two subsequent cuts after the uniformization cut. After completing these evaluations, a water defcit tolerance assessment was also conducted. The quantitative descriptors were subjected to analysis of variance, considering the two cuts. The obtained data were analyzed, and ten groups were formed, with the accessions UmCO-11 (2) and UmCO-2 (2) showing the highest genetic divergence. In conclusion, high variability was observed among the evaluated Urochloa accessions, which may indicate their potential for incorporation into breeding programs. The identifcation of genotypes tolerant to water defcit stress is of great value for ensuring productivity and the perenniality of pasture.
