Abstract:

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.
