Variety source: Zhendao 683/Xiangnuo 8333, test name "Taijingnuo 109"

Characteristic: Late-maturing medium japonica glutinous rice early-maturing variety. The plant height is relatively short, the plant type is relatively compact, the leaf posture is firm, the population is neat, the tillering power is higher, the ear formation rate is higher, the ear shape is medium, the seed setting rate is better, the color change during maturity is good, and the lodging resistance is good. The average results of the provincial and regional tests: the whole growth period is 146.2 days, which is 1.5 days shorter than the control Wuyunjing 27. The plant height is 91.1 cm, the effective ear per mu is 242,000, the total number of grains per ear is 119.7, the seed setting rate is 93.7%, and the thousand-grain weight is 28.2 grams. Appraised by the Plant Protection Institute of Jiangsu Academy of Agricultural Sciences: the loss rate of panicle neck blast is grade 5, the comprehensive resistance index of rice blast is 5.0, moderately susceptible to rice blast, bacterial leaf blight, susceptible to sheath blight, and resistant to stripe leaf blight. The physical and chemical indicators of rice quality were tested in 2019 by the Food Quality Supervision, Inspection and Testing Center of the Ministry of Agriculture and Rural Affairs (Wuhan): the whole rice rate is 69.1%, the gel consistency is 100 mm, the amylose content is 1.3%, and the aspect ratio is 1.7, reaching the level of the agricultural industry "Edible Rice Variety quality" standard three.

Yield performance: Participated in the early-maturing regional test of late-maturing medium japonica rice in Jiangsu Province from 2018 to 2019. The average yield per mu in two years was 706.2 kg, which was 7.9% higher than the control Wuyunjing 27. Participated in the production test in 2020, the average yield per mu is 686.7 kg, which is 6.0% higher than the control Wuyunjing 27.

The key points of cultivation techniques: 1. Sowing seeds at an appropriate time and cultivating strong seedlings. Planting is generally done in mid-to-late May. Plastic trays are used to raise seedlings with 110-120 grams per tray, and the amount of seed used in the field is 3 to 4 kg per mu. 2. Transplant at the right time and plant closely. Seedlings are 18-20 days old, transplanted in time, planted more than 15,000 holes per mu, and basic seedlings are 60,000 to 80,000. 3. Scientific fertilization and water management. A large area of ​​about 20 kilograms of pure nitrogen per mu is applied. The fertilizer management adopts the fertilization principle of "pre-weight, mid-control, and post-replenishment", and attaches importance to the combined application of phosphorus and potassium fertilizers and organic fertilizers. In terms of water slurry management, planting in shallow water, live trees with a inch of water, and tillering with thin water. When the stem and tiller seedlings per acre reach 80% of the ear seedlings, they should be placed in the field in time. The roots preserve the leaves and are ripe until they are old. The water is cut off a week before harvesting. 4. Comprehensive prevention and control of pests and weeds. Soak seeds with chemicals before planting to prevent seed-borne diseases such as bakanae disease and dry tip nematode disease. Concentrate control of rice thrips and Laodelphax striatellus during the seedling stage, and comprehensive control of sheath blight, stem borers, rice planthoppers, rice vertical rolls in the middle and late stages Leaf borer, rice blast, sheath blight, base rot, etc.

Approval opinion: Approved, suitable for planting in the Yang hilly area of ​​Suzhong and Ningzhen, Jiangsu Province.
