Abstract

Blueberry is related among "Super Fruits", has worldwide demand being one of the healthiest fruits containing large amount of antioxidant compounds. It is much appreciated for its exotic flavor and is considered as a source of longevity. The culture has a requirement of cold hours that vary according to the cultivar, for this reason, it is important to identify which are feasible for planting according to the climate of the region. Itaqui does not produce blueberry, and in this context, the present work aims to find in the literature blueberry cultivars that have the greatest possibility of adaptation to the crop in the municipality of Itaqui, based on the number of cold hours. Itaqui is in the range of 151 to 200 hours of cold and not recommended for the blueberry cultivation, however it is possible to cultivate with the cultivars of the Southern Highbush group as Emerald, Snowchaser, Farthing, San Joaquín, Kestrel and Ventura and the cultivars Misty and O'Neal which are adapted to the region with less availability of annual cold hours.
