Variety details

Source of varietiesA regular mid-season rice variety was bred by means of molecular marker-assisted selection using "YR0822" as the female parent and "Efeng Silk Seedling" as the male parent.
Yield performanceFrom 2018 to 2019, he participated in the regional test of the early-maturing rice group of the Hubei Seed Industry Innovation Test Consortium. The average yield per mu of the two-year regional test was 639.54kg, which was 6.83 higher than that of the control Huang Hua. Among them: 622.10kg per mu in 2018, accounting for 4.38 per cent more than Huang Hua; 656.98kg per mu in 2019, accounting for 9.26 per cent more than Huang Hua.
Main Indicators of Rice Quality: The rice quality was determined by the Food Quality Supervision, Inspection and Testing Center (Wuhan) of the Ministry of Agriculture and Rural Affairs. The roughness rate was 79.1, the whole rice rate was 64.2, the chalky grain rate was 5%, the chalkiness degree was 0.9, the amylose content was 15.0, the gel consistency was 62mm, the alkali dissipation value was 6.0, the transparency was 1, and the aspect ratio was 3.3, reaching the agricultural industry's "Edible Rice Variety Quality" Standard Grade II.
FeaturesThe plant type is moderate, the plant is shorter, and the tillering is strong. The leaf color is green, the sword leaves are quite. The panicle layer is neat, the middle panicle type, the grain is long, the lemma tip is colorless and has no awns. In the regional test, the plant height was 100.7cm, the effective panicle per mu was 253000, the panicle length was 22.5cm, the total number of grains per panicle was 149.7, the number of grains per panicle was 130.4, the seed setting rate was 87.1, the 1000-grain weight was 22.32g, and the whole growth period was 113.3 days, 2.1 days longer than Huang Hua.
resistanceThe disease was identified as rice blast comprehensive index 2.0, rice blast loss rate was the highest level 1, and it was resistant to rice blast. White leaf blight grade 5, moderate white leaf blight; Sheath blight grade 3, moderate resistance to sheath blight; Rice Qu -78-disease grade 5, medium-sensitive rice false smut. Heat resistance level 3, cold resistance level 5.
cultivation points:
1. Timely sowing. Sowing in mid-to-late May, the field generally uses 3.0kg of seed per mu, and it is advisable to soak the seed with prochloraz before sowing. Seedling 3~4 leaf stage in a timely manner to check seedlings.
2. Scientific weeding. 5 days before sowing, 3 days after sowing, seedling 3 leaves 1 heart stage and tiller stage timely weeding.
3. Scientific management of fertilizer and water. Plantar fertilizer, early application of top dressing, increase the application of phosphate fertilizer, potassium fertilizer, zinc fertilizer, silicon fertilizer, appropriate control of nitrogen fertilizer. Generally, 11~12kg of pure nitrogen is applied per mu, and the ratio of nitrogen, phosphorus and potassium is 1:0.5:0.8. The field surface shall be kept moist during the 1-3 leaf stage of the seedlings. After the 3 leaf stage of the seedlings, the seedlings shall be irrigated in shallow water frequently to promote the root and strong tillers. The tillers shall be controlled in the field in time during the tillering stage. The deep water layer shall be kept from the booting to the heading and flowering stage. The later stage shall be dry and wet until yellow.
4. Pest and disease control. At the seedling stage, attention should be paid to the prevention and control of rice thrips and southern rice black-streaked dwarf disease. In the field, attention should be paid to the prevention and control of rice false smut, sheath blight, rice blast, white leaf blight, stem borer, rice planthopper and other diseases and insect pests.
suitable rangeIt is suitable for planting early-maturing medium rice in areas other than southwest Hubei Province.
