PRODUCTIVITY OF SOME BLUEBERRY CULTIVARS UNDER LATVIA CONDITIONS
Success in the cultivation of highbush and half-highbush blueberry has been achieved in Latvia. The objective of the research was to evaluate highbush blueberry (Vaccinium corymbosum L.) cultivation possibilities in northern conditions. The field trial with six highbush and four half-highbush blueberry cultivars was established in western Latvia. To select cultivars for research, we took into consideration the winter hardiness of plants and harvest season of berries during 2007-2009. In 2007, the greatest winter hardiness was observed for Polaris, Chippewa, Northblue and Patriot, while the lowest winter hardiness was observed in Duke. In 2008 and 2009, changing weather conditions did not do significant damage to plantations. The yields of Patriot, Northland and Chippewa were the highest. The berry weight ranged from 1.1 to 2.6 g. Chandler, Northblue and Bluecrop had the largest berry size - an average diameter of 17 to 20 mm. The results showed that highbush blueberries grew well under Latvia conditions and we can recommend all of these cultivars for commercial cultivation, except for Chandler. The harvest season of Chandler was too late.
