Ticuna plants have an erect growth habit and their stems have thorns in similar densities to the Tupy and Guarani cultivars. The red pigmentation is medium to high on dormant branches, and weak on fast-growing branches.
The flowers of Ticuna blackberry have white petals with hints of violet. Full bloom usually occurs in the first half of October (South hemisphere) and ripening begins in the second half of November.
The fruits are large, oblong in shape, with medium to large drupelets and a predominantly acidic taste, resulting from the low to medium content of total soluble solids and high acidity. It may show color reversal in post-harvest, although less than that shown by the Brazos cultivar. It is only suitable for artisanal or industrial processing.
The Ticuna cultivar is recommended for the production of fruit for processing, mainly for the production of jams and chimies, and is not suitable for fresh consumption due to its predominantly acidic taste.
The productivity of the blackberry cultivar Ticuna depends on the cultivation system adopted (with or without support and irrigation) and the climate and soil conditions. On average, it can be considered 9 t/ha in a system without irrigation or support, but 18 t/ha in a system with irrigation and support.
Ticuna has been tested in the South and Southeast of Brazil and adapts to areas where the Tupy and Xingu cultivars adapt well.
Ticuna blackberry is moderately susceptible to orange rust.
