Approval Number: Hubei Rice Review 20253015

Variety origin: E Xiang Si Miao / Nong Xiang 32
Quality and Yield: In the 2023-2024 growing season, this variety participated in the regional trial for early-maturing medium-rice varieties under the Hubei Seed Industry Innovation Testing Consortium. The rice quality was tested by the Food Quality Inspection and Testing Center of the Ministry of Agriculture and Rural Affairs (Wuhan), yielding the following results: brown rice yield rate of 76.4%, milled rice yield rate of 64.1%, chalky grain rate of 4%, chalkiness degree of 0.8%, amylose content of 16.9%, gel consistency of 72 mm, alkali digestion value of Grade 6.5, transparency of Grade 1, and length-to-width ratio of 4.8—all meeting the Grade I standard specified in the agricultural industry standard "Quality of Edible Rice Varieties." Over the two-year regional trial, the average yield per mu was 553.5 kg, representing a 0.2% increase over the control variety Huanghuazhan. Specifically: in 2023, the yield per mu was 553.2 kg, a 4.5% decrease compared to Huanghuazhan; in 2024, the yield per mu was 553.7 kg, a 5.3% increase over Huanghuazhan. In the 2024 production trial, the average yield per mu was 575.7 kg, representing a 5.0% increase over the control variety Huanghuazhan.
Characteristic traits: This is a medium-season, conventional indica rice variety of early maturity. The plant type is moderate. The leaf blades are long and upright. The grains are elongated with colorless lemma tips. The maturity appearance in the later stage is excellent. In regional trials, the plant height was 129.6 cm, with 216,000 effective panicles per mu, a panicle length of 25.2 cm, a total grain number per panicle of 142.7, an average number of filled grains per panicle of 115.6, a filling rate of 81.0%, and a 1,000-grain weight of 25.05 grams. The entire growth period lasted 112.5 days, 1.0 day longer than the control variety Huanghuazhan. Disease resistance assessment showed a blast disease composite index of 4.3, with the highest blast damage rating at Grade 9, indicating high susceptibility to blast; a bacterial blight rating of Grade 7, indicating susceptibility to bacterial blight; and a sheath blight rating of Grade 5, indicating moderate susceptibility to sheath blight. Heat tolerance is rated at Grade 5, and cold tolerance at Grade 3.
Key cultivation points: 1. Sow at the right time. Generally, sowing is carried out from late May to early June. For open-field cultivation, the seeding rate is typically 2.5–3.0 kilograms per mu. Before sowing, it is advisable to soak the seeds in imidacloprid solution. During the 3- to 4-leaf stage of seedlings, promptly check and replenish any missing seedlings. 2. Implement scientific weed control. Weed promptly five days before sowing, three days after sowing, during the 3-leaf-1-heart stage of seedlings, and during the tillering stage. 3. Manage fertilizers and irrigation scientifically. Apply sufficient base fertilizer, apply topdressing early, increase the application of phosphorus, potassium, zinc, and silicon fertilizers, and appropriately limit nitrogen fertilizer application. Generally, apply 10–12 kilograms of pure nitrogen per mu, with a nitrogen-phosphorus-potassium ratio of 1:0.5:1. During the 1- to 3-leaf stage of seedlings, keep the field surface moist; after the 3-leaf stage, maintain shallow water and irrigate frequently. During the peak tillering stage, promptly drain the field to control tillering. From the booting stage through heading and flowering, maintain deep-water irrigation. In the later stages, alternate between wet and dry conditions until the rice turns yellow and matures. 4. Control pests and diseases. Focus on controlling blast and bacterial blight, and pay attention to preventing sheath blight, brown spot, rice thrips, stem borers, and planthoppers.
Suitable range: Suitable for medium-season rice cultivation in regions of Hubei Province other than southwestern Hubei. Not recommended for areas prone to or severely affected by rice blast.
