Tupy

The Tupy blackberry is the result of a cross between the Uruguay and Comanche varieties. This is global floricane-fruiting commercial cultivar in such regions as South and Central America. Stems are trailing, very thorny and vigorous. Tupy has high yield and very good fruit quality. It produces black firm fruits with excellent postharvest potential. Averaged berry weight is 5-7 g. Yield is about 5000 kg/ha (1.8 - 2.0 kg per plant). In the South Hemisphere harvesting begins in middle-late November and continues up to February, so fresh berries ships in many countries.
Heat tolerance is excellent. Tupy requires a normally chill of about 200 hours, but can be reduced. Some researches shows, that the cultivation of Tupy in mild winter regions (for example - subtropical areas) allows the harvest before the traditional harvesting period. This has an important market impact because it makes commercialization of fresh berries possible during periods of lower supply.
