The whole growth period is 139.4 days, 3.0 days longer than Fengliangyou No. 4. From 2014 to 2015, he participated in the regional test of medium rice varieties 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 80.9%, the head rice rate was 64.9%, the chalky grain rate was 27%, the chalkiness was 5.9%, the amylose content was 14.2%, the gel consistency was 88 mm, and the length width ratio was 3.2.

★ Adaptability
Yield performance: From 2014 to 2015, the average yield per mu of medium rice participated in the regional test of Hubei Province was 685.53 kg, which was 4.65% higher than that of CK Fengliangyou No. 4. In 2014, the yield per mu was 672.20 kg, 5.90% higher than that of Fengliangyou No.4; In 2015, the yield per mu was 698.86 kg, 3.47% higher than that of Fengliangyou No. 4.
Resistance: the disease was identified as the comprehensive index of rice blast 5.9, the highest loss rate of rice blast was 9 grades, and the disease was highly susceptible to rice blast; The bacterial leaf blight is grade 5, moderately susceptible to bacterial leaf blight; Sheath blight is Grade 7 and susceptible to it.

★ Main cultivation measures
1. Sow early in time and cultivate strong seedlings. The seeds are sown in the first half of April in northern Hubei, and in the Jianghan Plain and southeast Hubei from late April to early May. The seeding amount per mu in the seedling field is 7 kg, and the seed amount per mu in the field is 0.75~1.0 kg. It is advisable to soak the seeds with prochloraz before sowing. At the stage of two leaves and one heart of seedlings and 5-7 days before transplanting, 5 kg urea was applied to each mu to cultivate strong and tillering seedlings.
2. Transplant timely and insert basic seedlings. The seedling age is about 30 days. Row spacing 23.3 cm × 26.7 cm or 20.0 cm × 30.0 cm, 2 grain seedlings per hole, 60000 to 80000 basic seedlings per mu.
3. Scientific management of fertilizer and water. Heavy application of base fertilizer, early application of tillering fertilizer, supplementary application of ear fertilizer, and attention to increase application of phosphorus and potassium fertilizer in the middle and late stages. Generally, 13 kg 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, turn green in inch water, and tiller in thin water. When the number of seedlings per mu reaches 200000, sun the field in time, and sprout in deep water. Dry and wet alternate until the grouting is mature. Do not cut off water prematurely.
4. Disease and pest control. Focus on the prevention and control of rice blast, and pay attention to the prevention and control of rice false smut, bacterial leaf blight, sheath blight, 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
