Cultivation of highbush blueberry (Vaccinium corymbosum L.) has been increasing in Europe in recent years, in particular due to the availability of new genotypes suitable for cultivation in many different environmental conditions. The aim of this study was to evaluate the resilience and nutritional quality of 11 highbush blueberry cultivars and two new selections (from the New Zealand Institute for Plant and Food Research Ltd breeding program) in Mediterranean hot summer climate conditions by measuring plant yield, seasonality, fruit sensorial traits, and phytochemical content in the fruits.
The new blueberry genotype PFR005 showed a high level of adaptability to these environmental conditions, with the highest total plant yield, whereas PFR075 was the best genotype for nutritional characteristics. Among the cultivars, 'Cosmopolitan' showed the maximum average fruit weight, 'Blueray' and 'Hortblue Poppins' demonstrated a good sensorial profile, while the best cultivars from the nutritional point of view were 'Hortblue Poppins', 'Hortblue Petite', and 'Early Blue'.
New cultivars and new genotypes able to satisfy the needs of different users, have been identified. The integration of germplasm evaluation with a tailored breeding program will help to create new cultivars that will be useful for the expansion of blueberry cultivation in hot Mediterranean summer climate conditions, which up to now have limited this crop. © 2020 Society of Chemical Industry.
近年来，高丛蓝莓（Vaccinium corymbosum L.）在欧洲的种植量不断增加，这主要是因为有了新的适合在许多不同环境条件下种植的基因型。本研究的目的是在地中海炎热夏季气候条件下，通过测量植物产量、季节性、果实感官特性和果实中的植物化学物质含量，评估 11 个高丛蓝莓品种和两个来自新西兰植物与食品研究所（New Zealand Institute for Plant and Food Research Ltd）的新品种的弹性和营养价值。
新的蓝莓基因型 PFR005 对这些环境条件具有较高的适应性，总植物产量最高，而 PFR075 是营养特性最好的基因型。在品种中，'Cosmopolitan'表现出最大的平均果实重量，'Blueray'和'Hortblue Poppins'表现出良好的感官特性，而从营养角度来看，最好的品种是'Hortblue Poppins'、'Hortblue Petite'和'Early Blue'。
已经确定了能够满足不同用户需求的新品种和新基因型。通过将种质资源评价与定制的育种计划相结合，将有助于培育出新的品种，为蓝莓在炎热的地中海夏季气候条件下的种植扩张提供帮助，迄今为止，这种气候条件限制了该作物的种植。 © 2020 英国化学学会。
