Ten blueberry varieties cultivated in Guantang base, Zhejiang A & F University were used to evaluate valuable characters including tree height, crown width, bottom branch number, rhizome diameter, leaf fresh weight, leaf dry weight, leaf area, number of flower bud and leaf bud, and initial bloom stage. According to the basic principles of fuzzy mathematics, all determined characters of ten varieties were judged comprehensively. It was concluded that ‘Garden Blue’ and ‘Powder Blue’ were promising varieties in Lin’an district.
