Abstract: ‘Huaqin’is a mid-ripening and disease-resistant apple cultivar developed through crossbreeding‘Jinguan’（female parent）with a multi-resistant germplasm resource（male parent）selected by our research group. The fruit of this cultivar is long and conical,with an average weight of 103.28 g per fruit. The fruit ground color is light yellow,and the peel is red with partial coloring,large lenticels,and moderate density. The flesh is light yellow in color,with a crisp texture and a sweet flavor. The flesh is light yellow in color,with a crisp texture and a sweet flavor,indicating good fruit quality. Fruit peels exhibit a hardness of 7.2 kg · cm²,contain 14.10% soluble solids,and have a titratable acidity of 0.72%. Long-term field experiments demonstrated that‘Huaqin’was highly resistant to Glomerella leaf spot and apple Marssonina leaf blotch,with fruit ripening in early September and a 135-day fruit development period. It is suitable for cultivation in the Huludao area of Liaoning and the Baoding area of Hebei.
