★ Main characters of the variety
It belongs to medium maturity late indica rice variety.
The plant type and height are moderate, and the tillering ability is strong. The sword leaf is medium long, slanting and curling. The panicle layer is regular, the panicle is medium, and the grains are uniform; The grain is long, the lemma tip is colorless, and some grains have a short awn. In the regional test, the effective spike per mu is 189000, the plant height is 117.8 cm, the spike length is 26.5 cm, the total number of grains per spike is 176.0, the number of grains per spike is 149.4, the seed setting rate is 84.9%, and the 1000 grain weight is 26.58 g. The whole growth period is 135.1 days, 4.9 days shorter than Yangliangyou 6. From 2012 to 2013, he participated in the regional test of medium rice in Hubei Province. The rice quality was determined by the Food Quality Supervision, Inspection and Testing Center (Wuhan) of the Ministry of Agriculture. The rice yield was 80.2%, the head rice rate was 51.4%, the chalky grain rate was 85%, the chalkiness was 11.1%, the amylose content was 20.4%, the gel consistency was 47 mm, and the length width ratio was 3.1.

★ Adaptability
Yield performance: The average yield of medium rice in Hubei regional trials in 2012~2013 was 648.87 kg/mu, 5.66% higher than that of Yangliangyou 6. In 2012, the yield per mu was 660.25kg, 5.13% higher than that of Yangliangyou 6; In 2013, the yield per mu was 637.48kg, 6.22% higher than that of Yangliangyou 6.
Resistance: the disease was identified as the comprehensive index of rice blast 5.9, the highest loss rate of ear blast was 9, and the disease was highly susceptible to rice blast; Grade 5, moderately susceptible to bacterial blight.

★ Main cultivation measures
1. Sow early in time and cultivate strong seedlings. The seeds will be sown on April 20 in the north of Hubei, and on May 10 in Jianghan Plain and southeast of Hubei. The seeding amount per mu of seedling field is 6~7 kg, and the seed amount per mu of field field is 0.75~1.0 kg. Soak the seeds with prochloraz before sowing to cultivate strong and tillering seedlings.
2. Planting early in time to promote tillering. The seedling age of water raised seedlings is about 30 days, and that of dry raised seedlings is 15-18 days. Row spacing 23.3 cm × 26.7 cm or 20 cm × 30 cm, 2-3 grain seedlings per hole, 70000-80000 basic seedlings per mu.
3. Scientific management of fertilizer and water. The base fertilizer is mainly used, supplemented by topdressing. Generally, 13.5kg of pure nitrogen is applied per mu, and the ratio of nitrogen, phosphorus and potassium is 1:0.5:0.8. Transplant seedlings in shallow water, live trees in inch water, and tiller in thin water. Sun the field 20 to 25 days after transplanting to prevent lodging according to the seedling conditions. Keep the shallow water layer from booting to heading, dry and wet in the later stage, and cut off water one week before maturity.
4. Disease and pest control. Focus on the prevention and control of rice blast, and pay attention to the prevention and control of sheath blight, bacterial leaf blight, rice false smut, borers, rice planthoppers and other diseases and pests.

★ Suitable planting area
It is suitable for planting medium rice in areas outside the southwest of Hubei Province, but not in areas with frequent and severe occurrence of rice blast.

★ Planting season
It is recommended to sow from March 20 to June 5.
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.
