Prior to the launch of new cultivars, it is important to carry out studies to observe the productive behavior of plants in each soil and climatic condition. The objective of this study was to present production and physical-chemical characteristics of fruits of blackberry genotypes cultivated in the Campos de Cima da Serra do Rio Grande do Sul and to indicate genotypes with potential to be released as cultivars or to follow in the breeding program of culture. The experiment was conducted in 2018, in the municipality of Vacaria/RS, in the Embrapa Grape and Wine - Experimental Station of Fruticulture of Temperate Wheater. The following genotypes were evaluated: Cultivares Tupy, Xingu and Xavante, and selections Black 112, Black 139, Black 145, Black 181, Black 198, Black 212, Black 216 and Black 288. The following variables were analyzed: Production: Production per plant, production per hectare and number of fruits per plant. Post-Harvest: Average mass, length, diameter, soluble solids, juice pH and titratable total acidity. It was observed that the selections Black 145, Black 198 and Black 216, due to the high production of fruits, have the potential to be released as new cultivars, surpassing cv. Tupy and equaling the production of cv. Xingu. The Black 287, Black 288 and Black 212 selections are suitable for in natura consumption due to the chemical characteristics of the fruits.
