Variety source: Jinshui 1 was used as the female parent and "Korla fragrant pear superior plant (13- 1)" was used as the male parent for sexual hybridization, so as to select the pear variety bred by excellent single plant. 20 15 passed the joint examination (recognition) of Hubei crop variety examination Committee, and the variety examination number was eshenguo 20 1500 1.
Quality and yield: The content of soluble solids is 1 1.34%, the content of total acid (calculated by citric acid) is 0.78%, and the content of vitamin C is 13.26 mg/kg. The flesh is tender and crisp, with few stone cells and aroma. Experiments and trial planting were carried out in Wuhan, Laohekou and Yingcheng from 2003 to 2014. Generally, the fruit begins to bear fruit in the third year after planting. Five-year-old trees yield about 900 kilograms per mu, and seven-year-old trees yield about 2000 kilograms per mu.
Features: The tree has strong potential, upright posture, broad conical crown, grayish brown trunk and smooth bark. Strong germination rate, medium branching ability, yellow-brown annual branches, smooth epidermis, white lenticels, no fine hairs at the top and no acupuncture. The leaves are ovoid, the edges are sharply serrated, the leaves are sharp and pointed, and the leaf base is round. There are about 6 flowers per inflorescence, with white corolla and 5 ~ 8 petals. In the full fruit stage, short fruit branches are dominant, the fruit is nearly round, the skin is green, the fruit surface is smooth and flat, the sepals fall off, the calyx is deep and narrow, and the single fruit weighs about 260 grams. Wuhan generally germinates in the first half of March and matures in the first half of August.
Key points of cultivation: 1, garden construction. Pumping tanks to improve soil and apply enough organic fertilizer. For ridge cultivation, the plant spacing is generally 2 m× 4 m, and the plant spacing for shed cultivation is 4 m× 3 m. The pollinated varieties are Cuiguan and Jinshui 2, and the suitable distribution ratio is 4: 1 ~ 5: 1. 2, plastic trimming. According to the shape of heart-shaped or small crown sparse layer, scaffolding cultivation adopts "two-arm anterograde" tree; Young trees should be lightly pruned, and more branches should be thrown to cultivate a solid skeleton; Pruning in winter should be light, simple and long before shrinking, and short cutting should be used with caution. 3. Fertilizer and water management. Re-apply base fertilizer in autumn, mainly organic fertilizer, to enhance tree vigor; In mid-February, effective nitrogen fertilizer was applied as germination fertilizer; In mid-May, compound fertilizer was applied as strong fruit fertilizer. Irrigation in time during drought. 4. Flower and fruit management. Leave a single fruit on each fruit table, put a small white wax bag on 10 ~ 15 days after flowering, and put a big bag directly after 35 ~ 40 days. 5, pay attention to the prevention and control of pear rust, black spot and pear psylla, pear moth, pear net stinkbug and other pests and diseases.
Scope of application: Suitable for pear planting in Hubei Province.
