★ Main characters of the variety
Indica three line hybrid rice varieties.
In the upper reaches of the Yangtze River, the whole growth period of a season of medium rice was 152.0 days, 1.4 days longer than that of the control F You 498. The plant height is 122.3 cm, the spike length is 25.5 cm, the effective spikes per mu are 127000, the total grains per spike are 256.0, the seed setting rate is 81.6%, and the 1000 grain weight is 26.1 g. Main indicators of rice quality: head rice rate 67.7%, chalky grain rate 9%, chalkiness 2.7%, amylose content 16%, gel consistency 60 mm, length width ratio 3.0, reaching the second level of the standard of "Quality of Edible Rice Varieties" in the agricultural industry.


★ Adaptability
Yield performance: In 2016, participated in the regional test of the mid indica late maturing group in the upper reaches of the Yangtze River, with an average yield of 647.25 kg per mu, 3.12% more than the control F You 498; In 2017, the average yield per mu was 609.42 kg, an increase of 3.61% over the control F You 498; The average yield per mu in the two years' regional trials was 628.34 kg, 3.37% higher than that of the control F You 498; In the production test in 2018, the average yield per mu was 613.00kg, 4.96% more than the control F You 498.
Resistance: the comprehensive indexes of rice blast in two years were 4.1 and 6.0 respectively, the highest loss rate of ear blast was 7 grades, brown planthopper was 9 grades, heat tolerance at heading stage was 5 grades, and cold tolerance was 5 grades; Susceptible to rice blast, highly susceptible to brown planthopper, moderate heat resistance and cold resistance at heading stage.


★ Main cultivation measures
1. Cultivate strong tillers. In the upper reaches of the Yangtze River, plant a season of medium rice. According to the local ecological conditions, sow early at the right time. The seed consumption per mu in the field is 1.0-1.2kg, and the seed consumption per mu in the seedling field is 7-8kg. Persist in soaking the seeds with strong chlorine concentrate, sowing thinly and evenly, strengthen the management of fertilizer and water during the seedling period, and prevent and control rice planthoppers.
2. Planting early in time to promote tillering. Transplantation of water raised seedlings at 6-leaf stage, with seedling age of 30-35 days; Dry raised seedlings were transplanted at 3.5~4 leaf stage, and the seedling age was 18~22 days. It is required to plant reasonably and densely, with a spacing of 20 cm × 30 cm, 3 grain seedlings per hole, 70000-90000 basic seedlings per mu.
3. Medium fertilizer and water management, controlling nitrogen and increasing phosphorus and potassium. Heavy application of base fertilizer: 25~30kg of high concentration compound fertilizer or 35~40kg of common compound fertilizer per mu; Early application of tillering fertilizer: 5-7 kg urea per mu 5-7 days after planting, 8-10 kg potassium chloride per mu 20-22 days after planting. Increasing potassium fertilizer application per ear and grain: 12~15kg potassium chloride per mu shall be applied in the middle booting stage to promote large ears, multiple grains and strong seeds, and the application of nitrogen fertilizer shall be strictly controlled in the middle and late stages.
4. Scientific water management and pest control. Turn green with inch water, tiller in shallow water and wet water, enough for seedlings to dry in the field, keep shallow water at booting and heading stage, fill in dry and wet alternately, and drain water 6 to 8 days before harvest.
5. Timely prevent and control pests and diseases. According to the disease and insect forecast, timely apply medicine to prevent and control such diseases and insect pests as borers, rice planthoppers, sheath blight, rice false smut and rice blast.


★ Suitable planting area
It is suitable to grow one season of medium rice in Pingba hilly rice region of Sichuan Province, Guizhou Province (excluding Wuling Mountain Area), low and middle altitude indica rice region of Yunnan Province, Chongqing (excluding Wuling Mountain Area), and the rice blast lightly affected region in southern Shaanxi Province. It is not suitable to plant in areas with severe rice blast.


★ Planting season
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.
