★ Main characters of the variety
Indica three line hybrid rice varieties.
The whole growth period of double cropping late rice in the middle and lower reaches of the Yangtze River is 113.1 days, 5.3 days earlier than that of the control Wuyou 308. The plant height is 99.6 cm, the spike length is 22.5 cm, the effective spikes per mu are 206000, the total grains per spike are 144.1, the seed setting rate is 84.1%, and the 1000 grain weight is 25.7 g. Main indicators of rice quality: head rice rate of 68.1%, chalky grain rate of 7.0%, chalkiness of 2.1%, amylose content of 13.8%, gel consistency of 70 mm, length width ratio of 3.3, reaching the second level of the standard of "Quality of Edible Rice Varieties" in the agricultural industry.

★ Adaptability
Yield performance: participated in the regional test of late indica early maturing group in 2015, with an average yield of 586.20 kg per mu, 3.45% more than the control Wuyou 308; In 2016, the average yield per mu was 611.76 kg, 4.59% higher than the control Wuyou 308; The average yield per mu in two years' regional trials was 598.98 kg, 4.02% higher than that of the control Wuyou 308; In the production test in 2017, the average yield per mu was 606.24kg, an increase of 4.76% over the control Wuyou 308.
Resistance: the comprehensive indexes of rice blast in two years were 6.1 and 4.3, respectively. The loss rate of ear neck blast was the highest level, which was 7 grades. It was susceptible to rice blast, bacterial leaf blight, and had medium cold tolerance.

★ Main cultivation measures
1. Sow timely and cultivate strong seedlings. Sowing from June 22 to 24, the seed consumption per mu of the field is 1.2-1.4kg. Sowing thinly and evenly, and strengthening the management of fertilizer and water to cultivate strong seedlings.
2. Timely transplant and reasonably close planting. 5.5 Transplanting in leaf stage, suitable seedling age is 20~27 days, and planting density is 20 × 23cm, two rice seedlings are planted in each hole, and 70000-80000 basic seedlings are planted per mu.
3. Strengthen the management of fertilizer and water. The level of fertilizer required in the field is medium. Generally, 30~35kg of common compound fertilizer with 45% of total nutrient content is applied per mu. After transplanting and returning to green, 6~8kg of urea and 8~10kg of potassium chloride are applied as a topdressing. Ear grain fertilizer is applied according to the seedling conditions in the middle and late booting stages, and nitrogen fertilizer is controlled appropriately to increase phosphorus and potassium fertilizer. Implement the oriented management of water slurry of "vigorous root, strong stem and healthy body", shallow water to promote tillering, enough seedlings to sun the field, shallow water at booting and heading stage, alternating dry and wet during filling and fruiting, and water supply is cut off 6 to 8 days before harvest.
4. Comprehensive pest control. Focus on the prevention and control of rice blast, and strengthen the chemical control of rice leaf roller, rice stem borer, rice planthopper, sheath blight and other diseases and pests according to the occurrence law.

★ Suitable planting area
It is suitable to plant late rice in the lightly affected areas of double cropping rice blast in Jiangxi Province, Hunan Province, Hubei Province, Anhui Province, and Zhejiang Province, but not in the heavily affected areas.

★ Planting season
It is suggested to plant late rice in the middle and lower reaches of the Yangtze River from June 15 to June 25
Please pay attention to sowing and scientific management according to the specific arrangements of local climate, previous crops, seedling raising mode and planting habits, and according to the accurate time guided by the local agricultural technology department.
