摘　　要：以德宏州芒市五岔路乡油茶基地的6个油茶品种果实为试验材料,测定其经济性状、加工性能及脂肪酸组成和含量,与德林油4号进行比较,采用模糊综合评判法,以果形指数、单果重、果皮厚、鲜出籽率、干籽含油率、鲜果含油率和硬脂酸、棕榈酸、油酸、亚油酸、亚麻酸、花生稀酸含量等为评价因素,综合分析并排序。结果表明,果实形态方面,3、4、5号油茶品种均优于德林油4号,6个油茶品种单果重均大于德林油4号;出籽率方面,2号油茶品种高于德林油4号;3、4、5号油茶品种干籽含油率和鲜果含油率均高于德林油4号;6个油茶品种茶油不饱和脂肪酸含量均大于德林油4号。综合评价结果,4、3、5号油茶品种各项指标均高于德林油4号,可作为下一步油茶良种选育目标。The fruits of six Camellia oleifera varieties from the base in Wuchalu Township,Mang City,Dehong Prefecture,were used as experimental materials to analysis their economic properties,processing performance and fatty acid composition and content.Compared with Delinyou 4,the fruit shape index,single fruit weight,peel thickness,fresh seed rate,dry seed oil rate,fresh fruit oil rate,stearic acid,palmitic acid acid,oleic acid,linoleic acid,linolenic acid,and peanut dilute acid content were used as evaluation factors for comprehensive analysis and ranking by using fuzzy comprehensive evaluation method.The results showed that in terms of fruit morphology,varieties 3,4,and 5 were superior to Delinyou 4,and the single fruit weight of all six varieties was greater than Delinyou 4;the seed yield of variety 2,the oil content of dry seeds and fresh fruits of varieties 3,4 and 5,and the content of unsaturated fat acid in the six varieties were all higher than that of Delinyou 4.According to the comprehensive evaluation results,the various indicators of Camellia oleifera varieties 3,4 and 5 were better than Delinyou 4,which could be used as the next target for the breeding selection of Camellia oleifera excellent varieties.
