不同地理起源的油茶无性系品质的聚类分析

Analysis on Comprehensive Quality of Camellia oleifera Superior Clones from Different Geographical Origin by Cluster Way

以赣无油茶各无性系--产量、果实主要经济性状及其茶油脂肪酸的组成成分为品质指标,对25个无性系进行聚类分析,结果表明:油茶25个优良无性系可分三大等级。I类赣石848、赣无1、赣无11、赣834、赣抚20、赣831、赣无24和赣70;Ⅱ类有赣兴48、赣84-3、赣无12、赣68、赣8、赣55、赣无2、赣70、赣6、赣兴46、赣无15、赣无16、赣71和赣447;Ⅲ类有赣永5、赣190、赣永6和赣77024。油茶无性系存在较大的地理种源上引起的经济性状与油脂成分上的差异,地理种源起源相同的油茶无性系其经济性状与脂肪酸组成含量表现一定程度的相似性。

Based on the yield,main economic characters of fruit and fatty acids composition of the tea seed oil were the synthesize quality index of Camellia oleifera superior clones.Twenty-five clones of Camellia oleifera were taken by clustering analysis.The results showed as follows： It can be classified three types.The first category is Ganshi 848,Ganwu 1,Ganwu 11,Gan 834,Ganfu 20,Gan 831 and Gan 70;The second category is Ganxing 48,Gan 843,Ganwu 12,Gan 68,Gan 8,Gan 55,Ganwu 2,Gan70,Gan 6,Ganxing 46,Ganwu 15,Ganwu 16,Gan 71and Gan 447;The third is Ganyong 5,Gan 190,Ganyong 6 and Gan 77024.There were greater differences among each Camellia oleifera superior clones in economic characters of fruit and fatty acids composition due to geographical provenances.It showed the certain similarity in economic characters of fruit and fatty acids composition when they originated from the same geographical provenance.
