Blueberry culture has become more attractive to many pomiculturists due to the special quality of fruits and of their nutritive and nutraceutical value. The comparative research of 4 blueberry culture varieties: Duke, Draper, Patriot and Brigitta and 2 pruning variants proved different responses in similar culture conditions. The biological characteristics of the varieties selected manifested through different capacity of producing shoots in the collet area, through different reaction to pruning and through the capacity of forming inflorescences. Pruning influenced the growth in height of plants, the ramification capacity of the bush and the size of the fruits. Heavy pruning determined a bigger growth, larger fruits and eventually a higher capacity of production. From the studied varieties Duke was the earliest one but with a small production capacity, Brigitta was late and the most productive and Draper and Patriot registered mediate values.
