Comprehensive evaluation and analysis of fruit character and tung oil qualily of five regional varieties of Vernicia fordii in Zhejiang Province

In order to better and comprehensively evaluate the variety resources of Vernicia fordii in Zhejiang Province. This paper deals with the tung oil production, fruit characters and physic-chemical property of five main families of Zhejiang Zuotong, Zhejiang Wuzhaotong, Zhejiang Shaohua Dansheng Mantianxing, Zhejiang Shaohua Congsheng Qiutong, Zhejiang Duohua Congsheng Qiutong oil were investigated and tested, and cross combinations selected was carried out with fuzzy mathematics. The results show that three indexes of tung oil production, fruit characters and physicochemical property of Zhejiang Zuotong were the highest composite score respectively of 0.7,0.72 and 0.75, and Zhejiang Shaohua Congsheng Qiutong was the better, which local of two elite cultivar provide technique foundation for the families of V.fordii in Zhejiang Province and East China region.
