苹果品种繁多，不同品种果实品质特征相差悬殊，对不同品种的苹果品质指标数据进行测定、收集，为苹果新品种选育和加工利用提供理论依据。该数据集通过从不同生产地（山东、辽宁、河北、山西）采集‘乔纳金’、‘金冠’、‘华红’、‘寒富’、‘国光’、‘斗南’、‘华月’、‘瑞香红’、‘瑞阳’、‘瑞雪’、‘华庆’、‘维纳斯黄金’等12个苹果品种，收集整理了2019—2021年12个苹果品种果实的品质指标，包括硬度、可溶性固形物、可滴定酸、维生素C、呼吸强度、乙烯释放量、破裂力、破裂位移、破裂功、屈服力、屈服位移、屈服功、果肉硬度、果肉做功、L^*值、a^*值、b^*值、c^*值、h^*值，共19个品质指标。此次收集的数据集涵盖了果实的生理品质、果肉质地、色泽等方面，更加全面地体现出该品种的特性，对品种的评价可以做到更具有真实性和准确性。对不同苹果品种的品质指标建立与共享数据集，可让大众更加清晰地认识到苹果品种之间的性状差异，有针对性地开展育种与加工工作，同时还可以筛选出性状表现突出的品种，去选择其更加适宜销售的地域。

China is a large country of apple production, with many varieties, and the fruit quality characteristics of different apple varieties are very different. The data of apple quality indicators of different varieties are measured and collected to provide a theoretical basis for apple variety breeding, processing and utilization. The data set collected 12 apple varieties from different production areas (Shandong, Liaoning, Hebei, Shanxi), including ‘Jonagin’, ‘Jinguan’, ‘Huahong’, ‘Hanfu’, ‘Guoguang’, ‘Dounan’, ‘Huayue’, ‘Ruixianghong’, ‘Ruiyang’, ‘Ruixue’, ‘Huaqing’, ‘Venus gold’, and sorted out the fruit quality indicators of 12 apple varieties from 2019 to 2021, including hardness, soluble solids, titratable acid, vitamin C, respiratory intensity, ethylene release, bursting power Rupture displacement, rupture work, yield stress, yield work, yield displacement, pulp hardness, pulp work, L^* value, a^* value, b^* value, c^* value, h^* value, 19 quality indexes in total. The data set collected this time covers the physiological quality, pulp texture, color and other aspects of the fruit, more comprehensively reflects the characteristics of the variety, and the evaluation of the variety can be more authentic and accurate. The establishment and sharing of data sets for quality indicators of different apple varieties can enable the public to more clearly understand the differences in traits among apple varieties, carry out targeted breeding and processing, and screen out varieties with outstanding traits to select regions more suitable for sales.
