The breeding process, planting characteristics, cultivation and seed production techniques of the two-line hybrid rice variety Qiuliangyouxinzhan were summarized and analyzed. This variety was developed by cross breeding using the two-line sterile line Q201S as the female parent and the strong restorer line Xinlongzhan as the male parent. It is planted in the rice growing area of the middle and lower reaches of the Yangtze River and has shown high yield, good field growth, good lodging resistance, and excellent quality. This variety is suitable for planting in the rice growing areas of the middle and lower reaches of the Yangtze River. Its high yield cultivation techniques include timely sowing (mid to late May), seedling age within 30 days, and transplanting when the leaf age is 5.5-6.0 leaves; the appropriate planting density is 750 000 to 900 000 plants/hm2; applying sufficient basal fertilizer, early tillering fertilizer, and potassium fertilizer during the booting stage, with water management mainly based on alternating dry and wet cycles; after the previous crop is harvested, the soil is deeply plowed, and suitable pesticides are used for seed mixing and disinfection before sowing to effectively prevent and control pests and diseases. High yield seed production techniques include selecting hilly or plain areas with an altitude of 300-800 meters as seed production bases; reasonable arrangement of sowing time, with a difference of 10 days between parents’ sowing time, attention to the differentiation period of young panicles, and timely adjustment of flowering period; arrange a parent to parent ratio of 2: 12, with seeding rates of 6 and 30 kg/hm2, respectively; reasonable fertilization, timely application of ear fertilizer and foliar fertilizer; spraying gibberellin “920” when the maternal plant is heading at 25%, and using artificial pollination methods such as bamboo poles; according to the forecast of pests and diseases, applying 75% oxime bacteria · tebuconazole, triflumezine and other pesticides to control rice false smut, sheath blight, rice planthopper, rice leaf roller and other pests and diseases; strictly isolate and remove impurities; timely installment harvest of father and mother’s foundation. This paper provides a reference for further promotion of the variety.
