Systematic Cluster Analysis on the Major Taste Quality of Newhall Orange in China

Major taste qualities of Newhall Orange from 24 counties/cities of 10 production regions of China wereanalysed. Result of systematic cluster analysis showed that the edibility of Newhall fresh fruits from Gannan of JiangxiProvince(GN-JX), South of Hunan Province(S-HN), North of Guangxi Zhuangzu Autonomous Region(N-GX) and East ofGuangdong Province(E-GD) was the best with strong-sweet taste because of their proper TSS and low TA contents. Theedibility of Newhall fresh fruits from South of Sichuan Province(S-SC), South of Zhejiang Province(S-ZJ) and West of FujianProvince(W-FJ) was better with proper taste of sweet and sour for the proper TSS and TA contants, while that from the 3-Gorge Area and Danjiang-reservoir Area of Hubei Province(DJ-R of HB) was not as good as other regions for their strong-sour taste due to their high TSS and TA contents. Therefore, the authors suggested that the fresh fruits from GN-JX, S-HN,N-GX and E-GD should be supplied for the market before New Years Day by means of timely-harvesting, and that from S-SC, S-ZJ and W-FJ be supplied for the market before the Spring Festival by way of late-harvesting properly, as well as thatfrom the 3-Gorge Area be supplied for the fruit slack market after the Spring Festival by means of storing on trees.
