★ 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 114.4 days, which is 4 days earlier than the control Wuyou 308. The plant height is 99.2 cm, the spike length is 22.3 cm, the effective spikes per mu are 197000, the total grains per spike are 149.6, the seed setting rate is 83.6%, and the 1000 grain weight is 26.7 g. Main indicators of rice quality: head rice rate 63.0%, chalky grain rate 19%, chalkiness 4.6%, amylose content 15.3%, gel consistency 65 mm, length width ratio 2.8, reaching the national standard of "high-quality rice" level 3.


★ Adaptability
Yield performance: participated in the regional test of late indica early maturing group in 2015, with an average yield of 587.27kg per mu, 3.64% more than the control Wuyou 308; In 2016, the average yield per mu was 610.17 kg, 4.40% higher than the control Wuyou 308; The average yield per mu in two years' regional trials was 598.72 kg, 4.02% higher than that of the control Wuyou 308; In the production test in 2017, the average yield per mu was 594.10kg, 2.67% higher than the control Wuyou 308.
Resistance: the comprehensive indexes of rice blast in two years were 5.9 and 5.8 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, highly susceptible to brown planthopper, and had medium cold tolerance.


★ Main cultivation measures
1. Sow timely and cultivate strong seedlings. In the middle and lower reaches of the Yangtze River, double cropping late rice was sown from June 22 to 24. The seed consumption per mu of the field was 1.2 to 1.4 kg. It was sown thinly and evenly, and the management of fertilizer and water was strengthened 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 demand in the field is medium. Generally, 30~35kg of common compound fertilizer with 30% 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.
