　　摘要 以目前生产中主栽品种“芭尔德温”“园蓝”“粉蓝”“杰兔”和“灿烂”5个兔眼蓝莓为对照，以9项果实外观性状和8项果实营养品质为评价指标，对“科威尔”“莱格西”“珠宝”“绿宝石”和“明星”5个新引入品种进行适应性评价，以期为其推广应用提供科学依据。结果表明，所有品种间除Vc含量无显著差异外，果实单果重、果形指数、果洼、萼片、可溶性固形物、总糖、花色苷等指标均存在显著差异。引入的“绿宝石”和“珠宝”2个品种的单果重显著高于对照品种，两者的可溶性固形物虽显著低于“园蓝”和“灿烂”，但均显著高于对照品种“芭尔德温”和“粉蓝”。主成分分析提取了前4个主成分，累计方差贡献率达 85.227%。“绿宝石”“莱格西”“明星”和“珠宝”的主成分分析综合评价指数高于对照品种“粉蓝”“园蓝”“芭尔德温”和“杰兔”。表明“绿宝石”“莱格西”“明星”和“珠宝”4个品种果实品质优于对照品种，在黔东南地区可以推广种植。

　　Abstract In this study， it was evaluated that the nine fruit appearance traits and eight fruit nutritional quality of fruits from five good varieties introducted of “Cowell”“Legacy”“Jewel”“Emerald” and “Star”， in comparison with the current 6 years old “Baldwin”“Gardenblue”“Powderblue”“Premier” and “Brightwell” rabbiteye blueberry cultivars， in order to evaluate the adaptability of 5 newly introduced cultivars， and in order to provide scientific basis for their cultivation and application. The results showed that except the content of Vc， quality indicators were greatly different among different blueberry varieties.The single fruit weight of the introduced varieties of “Emerald” and “Jewel” was significantly higher than that of the control varieties， and their soluble solids were significantly lower than that of “Gardenblue” and “Powderblue”， however， it was significantly higher than the control varieties “Baldwin” and “Powderblue”. 4 main composition were extracted by pcomponent analysis，accumulative variance contribution was 85.227%.Comprehensive evaluation of blueberry quality showed that “Emerald”“Legacy”“Star” and “Jewelry” were all higher than the control varieties “Powderblue”“Gardenblue”“Baldwin” and “Premier”. The aforementioned results showed that the fruit quality of the four varieties of “Emerald”“Legacy”“Star” and “Jewel” was better than that of the control varieties， and could be widely cultivated in the southeast of Guizhou Province.
