Main indexes of rice quality: head rice rate 62.1%, length width ratio 3.0, chalky grain rate 18%, chalkiness 5.6%, gel consistency 90 mm, amylose content 12.9%.

★ Adaptability
Yield performance: In 2014, participated in the regional green channel test of medium indica late maturing group in the middle and lower reaches of the Yangtze River, with an average yield of 630.30 kg per mu, an increase of 4.39% over the control Fengliangyou No. 4; In 2015, the average yield per mu was 704.95 kg, 5.24% higher than that of Fengliangyou No.4; The average yield per mu in two years' regional trials was 667.63 kg, 4.8% higher than that of Fengliangyou No. 4. In the production test in 2016, the average yield per mu was 653.39 kg, 12.7% higher than that of Fengliangyou No. 4.
Resistance: the comprehensive indexes of rice blast in two years were 5.0 and 4.4, respectively, and the loss rate of ear blast was the highest in seven grades; Grade 5 of bacterial leaf blight; Brown planthopper 8; Susceptible to rice blast and moderately susceptible to bacterial blight.

★ Main cultivation measures
1. In the middle and lower reaches of the Yangtze River, middle season rice will be sown in the middle and late April, with a seed consumption of 1.0kg per mu of field and 6-7kg per mu of seedling field, so as to strengthen the management of fertilizer and water in seedling fields and cultivate strong seedlings.
2. Transplanting seedling age is 25-30 days, and the row spacing of planting plants is 20 cm × 30cm, double planting, planting about 70000-80000 basic seedlings per mu.
3. The level of fertilizer required in the field is relatively high, so more organic fertilizer should be applied, phosphorus and potassium fertilizer should be properly applied, 45-50kg of high concentration compound fertilizer should be applied per mu as the base fertilizer, 8-10kg of urea should be applied per mu as the tillering fertilizer 5-7 days after transplanting, 15kg of potassium chloride should be applied per mu from jointing to the early booting stage, and 12-15kg of high concentration compound fertilizer should be applied as the ear fertilizer depending on the seedling situation.
4. Transplant seedlings in shallow water, root and tiller in thin water. When the total number of seedlings per mu reaches 2.2-23 million, drain and dry the field. There is water layer in the field from the middle booting stage to full heading stage. Wet management is carried out during milk ripening and grouting period, and water is released 6-7 days before maturity. 5. Focus on the prevention and control of rice blast, borer, rice planthopper, sheath blight and other diseases and pests.

★ Suitable planting area
It is suitable to grow one crop of medium rice in Hubei Province (except Wuling Mountain Area), Hunan Province (except Wuling Mountain Area), Jiangxi Province, Anhui Province, Jiangsu Province, Zhejiang Province, northern Fujian Province, and southern Henan Province. It is not suitable to plant in areas with severe rice blast.

★ Planting season
In the middle and lower reaches of the Yangtze River, it is suggested to sow rice from April 1 to May 31.
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.
