　　Variety name: Anjiang Bingtang Pomelo

　　Breeding institution: Hongjiang City Agriculture Bureau, Hongjiang City Science and Technology Bureau, Hongjiang City Association of Senior Science and Technology Workers

　　Variety source: Seedling variation of Anjiang Xiangyou

　　Previous registration status: None

　　Characteristics: The Anjiang Bingtang Pomelo tree has medium vigor, a semi-spreading growth habit, strong sprouting and branching ability, and forms a canopy relatively quickly. The branches are relatively dense, thick and short, with an average leaf length of 8.7 cm and width of 5.6 cm. The leaves are acuminate or acute, and the leaf color is relatively green. In the Huaihua region of Hunan, spring shoots of this variety generally begin to sprout in early to mid-March, buds appear in late March, and the flowering period is about one week earlier than that of Guanxi Honey Pomelo in the same year. The full bloom period is in late April, the flowering decline period is in mid-to-late May, the first physiological fruit drop occurs after mid-May, and the second physiological fruit drop occurs in mid-June. Summer shoots begin to sprout in early June, and autumn shoots begin to sprout in mid-to-late July. Young trees mainly bear fruit on autumn shoots, typically on fruiting mother branches inside the canopy or at the lower part, while mature trees bear fruit in all directions with no obvious alternate bearing, showing good yield stability and high productivity. The fruits begin to color in mid-to-early October and mature in mid-to-early November. The average single fruit weight is 690 grams, with a regular shape and a pear-like form. The fruit surface has slightly raised oil glands and a strong aroma. The peel is relatively thin, with an average thickness of 1.21 cm, an edible rate of 53.2%, soluble solids content of 11.8%–13.1%, total sugar of about 12.1%, and vitamin C of 53.28 mg per 100 grams. The flesh is crisp, tender, and juicy, with honey-yellow juice sacs, pure flavor, and superior quality. The fruit has good storage capability and can be stored at room temperature for about 120 days. The Anjiang Bingtang Pomelo has strong adaptability and can be planted in both mountainous and flat areas, but grows best in sandy loam soil that is loose and well-drained.

　　Yield performance: Based on cultivation performance in the origin area of Hongjiang City as well as in Zhijiang County and Huitong County, this strain demonstrates good yield potential and early fruiting ability. Five-year-old trees yield 2,415 kg per mu.

　　Cultivation key points: Select suitable orchard sites and establish high-standard plantations. Use virus-free container seedlings, with planting densities of 3 m × 5 m or 3 m × 4.5 m. Planting should take place before the sprouting of spring shoots (late February to early March). For young trees, focus on promoting shoot growth and expanding the canopy; for bearing trees, use pruning methods such as thinning, heading back, and cutting back. Fertilization for young trees should mainly consist of organic nitrogen fertilizer, while for bearing trees, emphasize fertilizers that promote spring shoot growth and flower development, fruit retention, fruit growth and autumn shoot development, and post-harvest nutrition, with proper balance of nitrogen, phosphorus, and potassium. For pest and disease control, adopt a strategy of prevention first and integrated management, with special attention to controlling resin disease.

　　Registration opinion: This variety meets the registration standards and is approved for registration. It is suitable for cultivation in our province.
