ABSTRACT: Information on the production performance of blackberry in less colder regions are fundamentals to the expansion of the cultivated area and extension of management practices for cultivars adapted to climate conditions in Brazil. The research was carried out with the aim to evaluate the productive performance of different blackberries cultivars in altitude region of 1,387m with mild temperatures, situate at 18º14’56”S, 43º36’0”W, in Minas Gerais State, Brazil. It was carried during the seasons 2013/2014, 2014/2015 and 2015/2016. The blackberry cultivars evaluated were the following ones ‘Brazos’, ‘Guarani’, ‘Tupy’ and ‘Xavante’. Flowering and harvesting of cultivars were evaluated as well as climatological data of the area in order to relate the number of hours of accumulated cold less than 13°C, 10°C and 7.2°C with production and crop time. To determine the production, the mass of blackberries harvested per plant was measured. Production of blackberry cultivars was extended in altitude region with similar productivity to the other producing regions in Brazil. Productive performance of the cultivars varied according to the accumulation of cold hours with mild temperatures that occurred in cultivation region. ‘Brazos’, ‘Guarani’, ‘Tupy’ and ‘Xavante’ showed good adaptation, being ‘Brazos’ the cultivar most productive.
